Institute of Physics, London

The IOP was looking to relocate from Portland Place and open a new public institute to house the organisation’s membership activities, support its ambition to engage different communities, and make physics more accessible to a wider audience.

Based in ‘The Knowledge Quarter’, part of a 19th century Keystone conservation area in Kings Cross, the new headquarters provides education and exhibition facilities alongside a combination of office and public space with a basement auditorium and exhibition gallery, which are both open to the public.

Located at the junction of Caledonian Road and Balfe Street, the new IOP building replaces vacant shops that were in desperate need of regeneration. Architects TateHindle recognised this as the ideal space for the new headquarters and created a design that is both state-of-the-art, but respectful to the historical character of the neighbourhood.

As conservation was key in this project two main external brick facades on the original structure were retained, with an entrance bay inserted to create a visual slot through to the completely refurbished interior. In addition, the 5-storey development features floor-to-ceiling windows along Caledonian Road which also acts as a ‘shopfront’ and provides views of the exposed concrete walls within.

TateHindle added a one-and-a-half-storey extension to the original structure, which houses corporate meeting space for hire. Clad in solid Proteus HR 1.0mm VM Zinc panels with a Pigmento Blue finish, the façade remains in keeping with the uniformity of shopfronts on Caledonian Road; whilst perfectly complementing the brick and glass exterior on the lower levels and concrete interior.

Installed by Longworth Building Solutions, Proteus HR was specified because it is a lightweight, strong and versatile system that creates an optically flat aesthetic. The integrated modular rainscreen panels feature an aluminium honeycomb core, structurally bonded between two thin gauges of lightweight metal skin to create an optically flat panel.

Each panel is supported by the Proteus aluminium carrier system and ancillary components anchored to a cantilever steel frame from the underlying masonry structure. These allowed the panels to be hooked-on from behind, accentuating the sheer, smooth façade interrupted only by strips of lighter cladding built into the design to compartmentalise the flat elevations.

A distinctive and punctuating feature of this upper storey façade is a series of state-of-the-art ventilation stacks, also clad in a combination of solid and perforated single skin Pigmento Blue Proteus HR Zinc panels, with built in aluminium stiffening frames.

The stacks, which replace the original chimneys, are designed to draw in cold air at roof level and deliver it through floor-level grilles, using physics to reduce the carbon footprint of the building. A vertical column marking the main entrance to the building and a third floor façade facing onto Caledonian Road also features Proteus HR VM Zinc.

Taking the architect’s design from the outside in, Proteus SC perforated panels in 2mm aluminium with a RAL 7031 finish feature internally, with 20mm diameter holes carefully placed in an offset triangular pattern, to match those featured on the ventilation stacks.

Proteus SC is an engineered panel system that is offered in either solid, perforated or mesh panel formats. By utilising an extensive range of metals, colours, textures and forms it can add another dimension to any façade cladding project. The system can be manufactured in a variety of metals and from 1mm to 6mm in thickness. For internal applications, like the IOP, Proteus Facades provides contrasting fabric inserts and an acoustic insulation layer can be encapsulated within the perforated panels.

With a striking design that flows throughout the building, TateHindle, alongside main contractor Murphy Group and Proteus Facades have together created an outward-looking and contemporary building; perfectly answering the client’s brief for a space that makes physics accessible and embodies how it is woven into our everyday lives.

The Institute of Physics is the professional body and learned society for physics in the UK and Ireland. It inspires people to develop their knowledge, understanding and enjoyment of physics.

The organisation works with a range of partners to support and develop the teaching of physics in schools. IOP aims to encourage innovation, growth and productivity in the business including addressing significant skills shortages and providing evidence-based advice and support to governments across the UK and in Ireland.

Vue Cinema, Eltham

Based in Eltham, the new Vue Cinema development is designed by architect Chapman Taylor in collaboration with contractor Wilmott Dixon. The building forms a major part of Greenwich Council’s ambitious plans to transform the high street into an entertainment destination for the community, with the aim of increasing footfall and business opportunities in the area.

Proteus Facades fabricated flat and pre-curved Proteus SC perforated panels, with a bespoke pattern designed by Chapman Taylor in a light grey (RAL 9006) finish, for the upper levels. The single skin panels were manufactured from a sheet of 4mm aluminium with a polyester powder coat (PPC) finish, which offers the ideal combination of high strength and a good resistance to chemicals, chipping, scratching and other service wear as well as corrosion and UV weathering.

The bright façade complements illuminated and glazed elements of the building whilst masking the box like structure of the upper storey. The smooth corners on the first floor, achieved through innovative use of the curved cladding, offers a subtle nod to the Art-Deco cinemas of the 1930s; paying tribute to a time-honoured design with modern materials and methods of construction.

Each panel, installed by Express Group Ltd., is supported by the Proteus aluminium carrier system and ancillary components anchored to a cantilever steel frame from the underlying masonry structure. These allowed the panels to be hooked-on from behind, accentuating the sheer, smooth façade interrupted only by the perforated design.

The six screen cinema, which accommodates 731 standard seats and 126 VIP seats, is complemented by two restaurants and a ‘Sky Bar’ which wraps around the building on the first floor and cantilevers the lower levels. The underneath of the terrace is clad in bespoke, twisted soffit panels manufactured by Proteus Facades, with a dark grey (RAL 7023) PPC finish.

Eltham Town Centre is part of the council’s focus on four sites within the borough which also includes Charlton Riverside, Greenwich Peninsula and Woolwich town centre; all identified as key places that can best promote their overall vision for growth and prosperity across the district.

During development, the cinema provided more than 100 apprenticeship weeks across the construction, supply chain and design, and 60 per cent of the total spend has been spent within 10 miles of the project.

Proteus SC is an engineered panel system that is offered in either solid, perforated or mesh panel formats. By utilising an extensive range of metals, colours, textures and forms it can add another dimension to any façade cladding project. The system can be manufactured in a variety of metals and from 1mm to 6mm in thickness. For internal applications Proteus Facades can provide contrasting fabric inserts and an acoustic insulation layer can be encapsulated within the perforated panels.

York House, Kings Cross, London

Once described as unwelcoming and foreboding, York House in Kings Cross, which dates back to 1981, featured a complex brick façade, with a set back entrance and very small windows giving the building a stand-offish appearance as well as a poorly lit interior.

Following a £13 million refurbishment, the building, purchased by The Office Group, which provides flexible workspaces in London, Leeds and Bristol, has been transformed into a bright, co-working space, suitable for London’s thriving and growing businesses.

Designed by Architects dMFK, the 70,000sq. ft, eight storey redevelopment features both modern and traditional elements. An original Torigenus cast aluminium sculpture sits on the east side of the building, created by sculptor Geoffrey Clarke, whilst bold new additions include a double height entrance with offices above, as well as a set back roof extension and terrace on the 7th floor.

Proteus SC Perforated Aluminium cladding panels wrap around a parapet along the new terrace in a bespoke repeated zig zag profile, which blends softly with the sky and complements a brick lattice façade, set on a 45-degree angle. The perforated panels also span various windows on the upper elements of the building.

The Proteus SC cladding system at York House, manufactured from 2mm aluminium sheets, was specified with an Interpon D2525 Anodic Bronze Polyester Powder Coat (PPC) finish to all sides and 40mm perforations in a regular triangular grid.

Each panel, installed by Richardson Roofing, is supported by a recessed aluminium PPC framing system devised by Proteus Facades and coloured to match. The unique fixings discreetly hold the cladding system in place whilst allowing for a thinner perforated skin to be used without resulting in deflection or distortion, helping the façade remain both aesthetically pleasing and within budget requirements.

Furthermore, careful placement of the perforations allows for natural light to pass through new enlarged windows, comfortably illuminating the interior of the once darkened building, with no need for blinds and reducing the level of artificial lighting required. This, alongside the installation of solar panels, premium insulation and double glazing (taking the efficiency rating from G to A), have resulted in the redevelopment achieving a BREEAM ‘Excellent’ certification.

Proteus SC is an engineered panel system that is offered in either solid, perforated or mesh panel formats. By utilising an extensive range of metals, colours, textures and forms it can add another dimension to any façade cladding project. The system can be manufactured between 1mm and 5mm in thickness and an acoustic insulation layer encapsulated within the panel. For internal applications Proteus Facades can provide contrasting fabric inserts when the panels are perforated.

As The Office Group’s 38th workspace to open in the UK, and fourth in Kings Cross, York House has been completely regenerated into a luxurious sought-after building featuring state-of-the-art amenities including a café, gym, library and roof gardens with panoramic views of the city.

Alongside dMFK and Proteus Facades, other businesses involved in the redevelopment scheme, which officially opened at the end of 2019, include QS Quantem, structural engineer Webb Yates and contractor Collins Construction.

28 – 30 Hoxton Street, London (Project Drum)

Aviva, a British multinational insurance company and pensions provider, identified Hoxton Square as the ideal location to create a campus of offices and relocate its Digital Garage; a dedicated space where technical specialists, creative designers and business leaders collaborate to develop new ideas and services. As part of the development, known as Project Drum, Aviva purchased 28-30 Hoxton Square along with other buildings in the area.

28-30 Hoxton Square required a substantial level of refurbishment, which created the opportunity to extend the property to increase capacity and improve accessibility and the layout between two front facing blocks. Architects TTSP redesigned the three-storey structure, with an entirely new floor added to the front and rear elevations as well as the demolition of a single storey centre, which was rebuilt to four storeys.

A major part of the brief given to TTSP was to ensure that historic structural elements of the building were retained and left exposed whilst all new visible external elements were over-clad to harmonise with the original features. Working closely with TTSP, Proteus Facades provided support with the design of the rainscreen cladding system to ensure this challenge was met.

Proteus HR TECU Patina Madrid panels, installed by Openwood Facades Ltd, were chosen for the double height storey which sits atop of the central part of the building, with architectural fins to the south elevations and window frames designed to match. The patterned copper finish of the Proteus material perfectly complements the colours and textures of the surrounding buildings, whilst staying in keeping with the heritage of the original site that dates to the 1700s.

Proteus HR VM Zinc Quartz rainscreen cladding was also specified for the roof level of 28- 30 Hoxton Square, which provides a long, maintenance-free life and offers adaptability to various design styles ranging from traditional to modern.

Proteus HR was specified for both the TECU Patina Madrid and VM Zinc Quartz materials at Hoxton because it is a lightweight, strong and versatile cladding panel that creates an optically flat aesthetic that is highly suited for building facades. The integrated modular rainscreen system features an aluminium honeycomb core, structurally bonded between two thin gauges of lightweight metal skin to create an optically flat panel that is available in aluminium, steel, zinc, stainless steel, copper alloys and other materials.

To mirror the design of the external façade, Proteus HR TECU Patina Madrid panels were also specified for use on a double-width lift lobby, which acts as a bright and bold mid-section connecting various internal departments, including a state-of-the-art AV centre.

In addition, Proteus Facades supplied mesh screens fixed to windows along the rear elevation in a Polyester Powder Coated (PPC) finish, which remains a popular choice with architects because of its long-term performance and cost benefits.

All factors which resulted in the development being named as a finalist for the Mixology19 Awards in the Medium Commercial Interiors of the Year category.

Proteus Facades offers one of the widest ranges of TECU copper and copper alloys in the UK. This includes TECU Brass, TECU Copper, TECU Bronze, TECU Patina Madrid, TECU Gold, TECU Zinn, a tin-plated copper that weathers from silver to subtle grey tones, along with many others.

All the materials are available pre-patinated, which bypasses the gradual weathering process, so that the cladding panels take on the beautiful earth tones from the day the façade is installed. Proteus Facades also offers a range of other surface treatments that avoid, delay or accelerate the weathering process.

Originally built in the 1700’s as an upmarket residential development, by the late 20th century Hoxton Square became the place to be for artists, musicians, photographers and other creatives in London, which attracted crowds from across the city. As digital technologies have prevailed however the area is now home to a number of leading digital and tech led businesses like Aviva.

Northampton International Academy

What was once the Royal Mail Sorting Office on Barrack Road, has now been redeveloped into an iconic school featuring a reflective Proteus SC Perforated Stainless Steel façade.

After closing due to a fire in 2003, the building remained uninhabited for over a decade and fell into disrepair. Once described as an eyesore of the city, the structure has now been given a new lease of life as Northampton International Academy.

Helping to respond to a significant requirement for school places in the city, Architecture Initiative identified the old sorting office as the ideal space for the new state-of-the-art school.

Working closely with the local authority, the London-based architects redesigned the colossal, brutalist building, which was originally opened by Princess Diana on her first solo engagement in 1981, into an education hub filled with natural light.

The Proteus SC Perforated panels installed at Northampton International Academy cleverly mask the monolithic appearance of the original structure, whilst not completely hiding this brutalist piece of architecture. The mirror polished surface on the face of the panels reflects the skyline giving the impression that the building is less imposing.

Reducing the perforation sizes from the middle of the façade to the top and bottom edges, maximises translucency, whilst acting as brise soleil, providing shade from solar glare and preventing over-heating to the teaching spaces.

The single skin perforated panels were manufactured from a sheet of 2mm Stainless Steel, which offers the ideal combination of high strength and a modern, progressive aesthetic. The material also holds excellent corrosion resistant properties.

Each panel, installed by Deane Roofing & Cladding, is supported by the Proteus aluminium carrier system and ancillary components anchored to a cantilever steel frame from the underlying masonry structure. These allowed the panels to be hooked-on from behind, accentuating the sheer, smooth façade interrupted only by the perforated design.

Northamptonshire is known for its history of crafting leather goods, particularly the art of traditional shoemaking. So taking the design process one step further, Proteus Facades worked closely with Architecture Initiative to create perforations that acknowledge this heritage; with the holes on each panel positioned to imitate those found on a Northampton-made brogue-style shoe.

In addition, careful placement of the small and large perforations allows natural light to pass through and flood the interior of the school, whilst the metal façade is rendered virtually invisible from the inside. This innovative approach is just one of the reasons Northampton International Academy was named one of the “boldest” buildings of 2019 by the Royal Institute of British Architects.

With a floor area of 22,250m2 and generous high ceilings, the academy, run by the EMLC Academy Trust, accommodates over 2,220 pupils, including 420 primary, 1,500 secondary and 300 sixth formers.

The front of the school houses two illuminated signage boxes that indicate separate entrances for primary and secondary pupils, which perfectly complement the mirror polish of the Proteus SC panels.

Proteus SC is an engineered panel system that is available in either solid, perforated or expanded mesh formats, and in an extensive range of metals, colours, textures and forms. The system is available between 1mm and 5mm in thickness and can be specified with an acoustic insulation layer encapsulated within the panel. For internal applications Proteus Facades can also provide contrasting fabric inserts when the panels are perforated.

Delivered by Northamptonshire County Council with funding from the Education and Skills Funding Agency and developed by Contractor, Vinci Construction, Northampton International Academy is one of the largest education conversion projects in the country.

Mulberry Park School and Community Hub

The £10 million Community Hub, commissioned by housing association Curo and designed by architects BDP, sits at the heart of Mulberry Park, the renovation of the former Ministry of Defence site on Fox Hill in the village of Combe Down on the southern fringes of Bath.

The eye-catching building features Proteus SC perforated TECU Gold panels with a PPC coated aluminium support frame on the school hall and the third floor cantilevered above the main entrance and Public Square. This section, installed by Cladanco, acts as an enterprise space and was inspired by the temporary floating Mulberry Harbours once used for the Allied invasion of Normandy during the Second World War.

Proteus SC is an engineered panel system that is offered in either solid, perforated or mesh panel formats. By utilising an extensive range of metals, colours, textures and forms it can add another dimension to any façade cladding project.

The perforated pattern of the Proteus SC panels at Mulberry Park is derived from historic aerial photographs of the harbours and was developed in conjunction with the supporting frame, which was required due to limitations in material thickness. Using Proteus SC and the company’s unique framing system meant that a thinner perforated skin could be used on the face of the panel without resulting in deflection or distortion, helping the striking façade remain within budget requirements.

Complementary Proteus HR solid TECU Gold rainscreen cladding panels feature at ground floor level, adding structure and providing an aesthetically pleasing, hardwearing layer that protects the building from the elements.

The Proteus HR honeycomb core of the rainscreen cladding system involves structurally bonded two thin gauges of lightweight metal skin such as copper alloy to the honeycomb core. Each panel is supported by the unique Proteus system of aluminium carriers and ancillary components, which can be installed on to any type of wall construction.

Proteus TECU Gold is a mix of copper and aluminium and offers outstanding mechanical abrasion and is highly corrosion resistant and durable. The initial bright gold appearance of the façade will gradually oxidise following installation, forming an enchanting warm golden surface.

Buildings featuring cladding systems made from copper alloy materials, like the Mulberry Park Community Hub, provide a vast scope of opportunities for architectural creativity. The striking natural, ever-changing surface creates unique, one-off designs that simply aren’t possible with some other cladding materials

This is one of the reasons the Mulberry Park Community Hub was recently crowned the winner of the South West Community Benefit category at the Royal Institute of Chartered Surveyors (RICS) Awards 2019. The award recognises outstanding achievement in providing a facility that directly benefits the local community and can demonstrate its success through local community feedback.

RICS judges commended the project team — BDP Architects, housing association and housebuilder Curo, Rydon Construction and surveyors Ridge & Partners — “for creating an exemplary community hub that is a trailblazer for future community buildings.”

With a distinctive design, it is no doubt that the Mulberry Park Community Hub will be valued by the people of Fox Hill, Combe Down and Mulberry Park and shine bright as a beacon of the local community for future generations – thanks in part to its aesthetically pleasing, gold facade.

Mulberry Park supports a contemporary development of 700 high quality homes and open spaces. Within easy reach for local residents, the community building, fronting on to a new public square, accommodates a 210-place primary school, a 70-place nursery and public use facilities including a café, clinic, a fitness suite and business enterprise and flexible spaces for hire.

Proteus Facades Ltd offers a wide ranges of TECU copper and copper alloys in the UK. This includes TECU Copper, TECU Bronze, TECU Brass, TECU Gold, and TECU Zinn. Some of these materials are also available pre-patinated, which bypasses the gradual weathering process, so that the cladding panels take on the beautiful earth tones from the day the façade is installed.

Spanish City, Whitley Bay

Although Spanish City closed in 2002, it has remained a local beacon and so became the focal point of North Tyneside Council’s £36m seafront masterplan, undergoing a £10m restoration and regeneration to bring it back to its former glory.

As a listed building protected by English Heritage, it was essential that the redesign by ADP architects retained as many of the building’s original features as possible, including the copper Terpsichorean female figures or ‘dancing ladies’, which were restored and positioned on top of two redeveloped Cupolas.

Alongside this was the addition of a bold extension featuring Proteus SC perforated TECU Patina, which was applauded by the judges when ADP’s vision for Spanish city secured a RIBA North East Award 2019.

ADP Architects specified TECU Patina for Spanish City, a copper material that features the natural green patina from the outset, as it created a beautifully aged aesthetic that complements the ‘old’ copper finish of the dancing ladies.

The homogenous pattern featured on the Proteus SC perforated cladding covers the entirety of the new extension at Spanish City, making it difficult to discern the position of the different floors and giving the structure a monolithic presence that is able hold its own against the imposing dome on the original building.

Choosing round perforations or ‘holes’ was no accident, it creates a contrast with the right angles of the surrounding cityscape, but mirrors the internal layout. A defining feature of the building is its extremely complex geometry, in fact only four rooms have walls in a square format, every other space is curved or a polygon, including the impressive rotunda which the panels were designed to meet.

The Proteus SC TECU Patina perforated copper cladding panels were fixed over extensive glazed areas at Spanish City, so both sides were visible by people inside the building and from those outside. This presented an engineering challenge because the architects envisaged large perforated panels due to the sheer size of the façade (larger cladding panels on large facades can look more visually striking), which can require thicker gauge metal.

Working with ADP architects Proteus devised a rear supporting aluminium PPC framing system that was discrete and avoided having to increase the thickness – and cost – of the copper material. The outcome was that it enabled the panels to be designed to meet the maximum optimisation of material, whilst meeting the challenging geometry of the project.

As Spanish City occupies a spectacular seafront setting overlooking the North Sea coast, it is susceptible to harsh coastal climatic conditions, which include high winds and salty sea and air. The Proteus SC perforated cladding panels will go some way to protecting the building from the elements, which was a major factor in causing the wear and corrosion that saw the demise of the original structure.

After more than two years of redevelopment work, by Robertson Group, the magnificent building is back to its former glory, transformed into an impressive mixed-use leisure venue that once again acts as a hub for tourists and members of the community.

The new extension block, clad by Chemplas Ltd, in Proteus SC perforated TECU Patina, to the rear of the building houses the new level-access entrance, toilets, plant and staircase that ensure compliance with modern standards.

Spanish City remains an iconic part of Whitley Bay’s heritage and a striking example of how old and new architectural styles and materials can work together. The building is now home to a Fish & Chip restaurant and takeaway, waffle and pancake house, Champagne bar, fine-dining restaurant, traditional tearooms and an event space.

Proteus Facades Ltd is able to offer a wide ranges of TECU copper and copper alloys in the UK. This includes TECU Copper, TECU Bronze, TECU Brass, TECU Gold, and TECU Zinn. Some of these materials are also available pre-patinated, which bypasses the gradual weathering process, so that the cladding panels take on the beautiful earth tones from the day the façade is installed.

Spanish City in Whitley Bay, is a collection of Edwardian seaside pleasure buildings and grounds. Built in 1910, the iconic structure, which once included a concert hall, restaurant, tea room, ballroom and funfair, attracted thousands of people from across the UK until it fell into disrepair in the 1970’s.

University of Bristol, Life Sciences Building

The £56.5m Life Sciences Building features a radical, undulating façade executed in Proteus HR solid and SC perforated free-form concave and convex panels with half-circle radii geometry.

The visual impact of Sheppard Robson’s design has been a beacon for the department, and the university reported a 40% rise in admissions in the two years following its completion.

The entire western block of Bristol Life Sciences is sheathed behind a striking combination of Proteus HR and Proteus SC solid and perforated, curved and flat aluminium panels that wrap, ripple and sheer across the facade.

Distinctly different in form, it is this west-facing wing with its gently snaking façade that defines this building. The striking geometry of the Proteus HR and SC façade establishes a new landmark on the Bristol skyline.

Proteus HR and SC are versatile and flexible solutions that provide aesthetic screening to building facades. Proteus SC is a single-skin metal panel system that can be specified as solid, perforated or mesh formats. Proteus HR panels have a honeycomb core to achieve a lightweight, perfectly flat surface, creating a powerful contrast to the curved panels below.

In a radical move by the architects, the large 1.5 m diameter ducts that provide services to the environmentally-controlled laboratories are located outside the building insulation line. These are expressed as bulbous shafts ribbed across the façade and shrouded by Proteus HR solid, curved aluminium panels.

Interwoven between these are three bands of window openings. In order to manage natural light levels inside the laboratories, the windows are set back deep within recesses and semi-obscured by the Proteus SC perforated panels that appear as bulbous, puffed-out, skeletonised versions of the curved HR panels around the service ducts.

The solar shade provided by the perforated panels reduce cooling loads within the teaching half of the building by enabling the use of exposed slabs with active chilled beams. This minimised floor to ceiling heights and that in turn enabled an entire floor height to be saved, which helped in planning and conservation terms.

Repositioning the service ducts to the outside of the also building had practical benefits because it enabled reconfiguration of the internal modular laboratory spaces in order to adapt to future requirements.

The overall appearance of the west-wing is staggering, with a beguiling industrial and machine-like appearance that is a perfect representation of the complex scientific activities that take place within.

Sitting above this sinuous, façade is a counter-balanced pod that features Proteus HR solid cladding panels in a tall, elongated arrangement. The optically flat, sheer face of the Proteus HR panels transition from the wrapped and rippled facade below with the help of swept curves around the edges of the overhanging pod.

A spokesperson from Sheppard Robson architects said: “Our goal on this project was to create a building that respects the neighbouring listed buildings and surrounding conservation area whilst also adding a confident piece of contemporary design to Bristol. The cladding panels have created a sinuous organic aesthetic that reflects the nature of the activities inside.”

The Life Sciences Building now has one of the largest learning labs in the country, capable of teaching 200 students at once. There are multiple screens to ensure all students can see close-up what the lecturer is doing and moveable walls can change the size of the space.

Bristol Life Sciences Building was shortlisted in the RIBA Awards and Education Estates Awards. It was designed by the architects Sheppard Robson and built by VINCI Construction UK.

70 Wilson Street, London

70 Wilson Street has been refurbished and extended in collaboration with Low Carbon Workplace to create a highly efficient, futureproof office space with BREEAM Excellent rating based on low carbon standards.

This was a highly complex façade that pushed the limits of technical performance, design engineering and manufacturing capabilities.

Proteus worked with A Studio, the architects for 70 Wilson Street to overcome a number of project specific challenges.

Proteus Facades provided a series of panel systems all covered with a TECU Iron Two material in a number of formats, including solid honeycomb panels, perforated screens and insulated spandrel panels.

The main visual panels on Wilson Street include vertical and horizontal beam cladding of Proteus HR panels. These panels connect to structural aluminium PPC Proteus spandrel panels that have built in steel beams to assist in taking the loading of the external visual panels.

The perforated screens sitting in front of the Kawneer glazing system were designed to span floor to floor and incorporate steel framing within the panels, cleverly cloaked with the TECU material to blend into the overall façade. The connection of these Proteus SC brise soliel panels was integrated with the design of the structural spandrel panels so they visually look as though they are floating in the air.

At the higher levels of the building the panels are integrated with the Kawneer curtain walling system. The architectural team had designed a glazing pattern of 1500mm widths, creating the challenge of integrating the TECU Iron 2 material, which was available in a 1000mm maximum sheet width.

Proteus, working with the installer, JPJ Installations, designing a multi faced spandrel panel to overcome this issue. The glazing unit sizes we’re compartmentalised into panel cassette sizes that could be produced from the base material. These four panels were then joined together and formed into one spandrel panel with integrated insulation and structurally supported and tied together with horizontal steel cross members, before finally being anchored back to the curtain walling.

Once this engineering challenge had been overcome, a combination of Proteus cladding systems in TECU Iron Two – solid and perforated face formats – were specified by A Studio architects.

“We knew that the façade for 70 Wilson Street was going to present a number of engineering and manufacturing challenges,” said Nick Gazanis, Associate Architect at A Studio. “That is why we identified a façade supplier that had the expertise to cope with the refit, new build and facade retention elements of this project.”

He added; “In terms of façade engineering, 70 Wilson Street is a masterpiece, yet the observer is unaware of the amount of design ingenuity that went into creating what is a stunning overall aesthetic, because it is completely hidden behind the panels.”

The Proteus façade elements were specified in KME’s new TECU Patina Iron Two material, which was chosen by A Studio and the developer, Stanhope, because it combines an attractive natural copper surface finish, with the weathered look of steel. It retains all the benefits of copper, such as excellent formability and unrivalled durability, with long term low maintenance.

The material creates an ever changing aesthetic, depending on whether it is in light or shade, dry or wet. Its natural weathered appearance matures over time to create subtle mellow tones.

Additional scheduling complexity during installation of the façade arose because 70 Wilson Street is located in a very busy part of the City of London. This required planning of deliveries in fine detail and ensuring the façade elements fitted right, first time, with no margin for error. Proteus assembles all façade elements in its manufacturing facility to ensure they fitted on site.

The developer and owner of 70 Wilson Street is Stanhope. Main contractor was Wilmott Dixon. Façade installer was Essex-based JPJ Installations Ltd.

Northampton University Energy Centre

Further visual interest was added to this project by the juxtaposition between the Proteus SC perforated panels specified for the flue stack and Proteus HR solid cladding panels used to create the unusual vertical saw-tooth façade design on the Energy Centre’s main building.

This was a challenging project for MCW architects because the designers had to work around the constraints imposed by the requirement for a large ‘box’ like structure to house a 1MW biomass boiler, four 4MW gas boilers and a 120m³ thermal store.

Proteus HR solid metal skin with honeycomb core was used around the thermal envelope of the building combined with polycarbonate cladding in a striking internally lit vertical “saw-tooth” arrangement. The lightweight, exceptional flatness, strength and rigidity of Proteus HR panels allowed the architects to develop a large modular cassette system (2500x1000mm), which was replicated around the building providing uniformity across different façade elements.

An equally engaging aesthetic was achieved on the 26m high stack by wrapping it in the Proteus SC perforated ‘skin’, creating a sense of weightlessness in what would, at the height of three London buses, have been quite an imposing structure. The back-lit random perforations now appear as though they are pixels being projected outwards from the 12m LCD screen, whilst the elongated landscape perforated panels play with the eye to visually truncate the stack’s overall height.

The screen itself provides the university with a useful information bulletin that showcases courses and events as well as being an advertising medium, both of which have the potential to generate a useful secondary income stream.

In order to achieve the ‘random’ pattern for the perforations, each of the Proteus SC panels on the flue stack had to be manufactured to a specific drawing reference and to millimetre tolerances. This involved changing the location, number and layout of the perforations on each panel. The pitch of each hole had to be calculated so that they passed seamlessly over panel joints.

Proteus also addressed the aim of establishing a seamless link between its perforated panels on the stack and the 12m high LED screen. This was done by working with the architects, screen suppliers and façade installers, Deane Roofing and Cladding, to create a bespoke tray system allowing the screen to be recessed and the perforated panels butted up flush with the edges.

While the building function is essentially utilitarian and technical, the external envelope has been developed to create a visually strong elevation to the campus celebrating the University’s commitment to sustainability.” said MCW architects. .”

Both the Proteus SC perforated and Proteus HR solid cladding panels are executed in polyester powder coated aluminium in RAL 7044 Silky grey, creating visual integration between the stack and main building below.

The new Energy Centre forms part of the £330m Waterside Campus Development at the University of Northampton. It will provide sustainable heating and hot water for all the buildings and student residencies on the 58 acre site, whilst saving over 1,000 tons of CO2 in the short term, rising to 2,200 tons a year following the introduction of a Combined Heat & Power Engine.
