WINNING WAYS WITH COPPER It is a pleasure to open this issue with the results of the 2017 European Copper in Architecture Awards.

But there is far more to read as well, with a wide selection of other projects from around Europe and well beyond, and our second ‘Copper Inside’ interior design supplement.

This year’s 18 th Awards programme (pages 4-9) again revealed some of the best contemporary European architecture. Congratulations to those who received awards or were shortlisted and thanks to everyone who participated.

We are also grateful to all those of you who voted via copperconcept.org for a ‘Public Choice’ winner.

In Sydney, a prominent apartment building – and 2016 World Architecture Festival Finalist – is characterised by perforated copper ‘wings’ protecting south facing balconies (pages 24-25). Also showcasing copper in conjunction with brick is a high-rise tower with surrounding buildings in Birmingham (pages 26-29).

Moving on from the Awards, we visit a metro station ticket hall in Helsinki where floating copper elements, envisaged as ‘leaves’, play a purely aesthetic role (pages 10-13). In contrast, alternating houses in an Amsterdam regeneration development are enwrapped in a protective, golden copper alloy skin forming walls and roofs (pages 14-17).

Next, copper plays the leading role in a technology building in Cottbus, Germany, to deliver its slick horizontality (pages 30-32). In Vantaa, Finland, a complete external skin of prepatinated copper now protects a weather-worn brick church (pages 33-35).

Our central feature explores the extensive and innovative application of copper alloy – again, for both walls and roof – on a new museum at the heart of Chengdu, China, demonstrating the material’s particular suitability for massive new buildings (pages 18-23).

Our final pairing considers museums in the desert. At a UNESCO World Heritage site in Saudi Arabia, bronze complements the stone walls of new structures as well as historic mud remains (pages 36-37). Similarly, copper features as part of a limited palette of enduring materials for a visitor centre celebrating a Bronze Age archaeological site in Sharjah, UAE. We hope you enjoy reading this issue.

AWARDS 2017

Copper in Architecture Awards

copperconcept.org/awards

The results of the 2017 European Copper in Architecture Awards have been announced, as judging panel moderator and Editor Chris Hodson reports.

The European Copper in Architecture Awards programme celebrates the beauty and versatility of copper and its alloys through some of the best contemporary architecture. It also seeks to expose to a wider international audience inspirational projects, some of which might otherwise go unrecognised. The judging panel for this eighteenth iteration of the biennial awards consisted of four architects, all recipients of previous awards: Ebbe Waehrens (BBP ARKITEKTER, Copenhagen), Maxime Enrico, (LAN, Paris), Ville Hara (Avanto Architects, Helsinki) and Craig Casci (GRID Architects, London).

WINNER

MAERSK TOWER Copenhagen, Denmark C.F. MØLLER ARCHITECTS This major research building was designed as a sustainable landmark, in dialogue with the city and university, acting as a catalyst for positive urban development. The 15-storey tower rests on a series of low buildings containing common functions including auditoriums, classrooms and canteen.

The facade is a grid comprising vertical copper fins that give varying shadow effects and changing apertures for the researchers’ workplaces throughout the day. The façadehigh windows with their copper fins, a third of which have sun-activated movable sections, help to reduce significantly the cooling energy requirement.

The fins are truncated triangular copper-clad units split into two parts. Alongside the static part a sensor-controlled movable ‘wing’, covered with expanded copper, shields the glazing, moving in step with the sun’s path across the sky.

The expanded copper maintains transparency for a pleasant, diffuse daylight and outlook over the surroundings. It also gives an open feel to the building suggesting that the city can look in on the Tower’s research.

Entries were assessed from photographs, drawings and descriptions submitted by their architects. Overall architectural design, response to programme and context, importance of copper to the scheme and its detailing were all considerations. Choosing from the 35 entries, with major public buildings alongside modest domestic schemes, presented a real challenge and generated lively debate. But the judges eventually agreed on a shortlist of 8 projects that stood out from the rest with a diversity of typologies and design approaches – and some exceptional architecture.

They then went on to select an overall Winner and two Commendations. Our website users also had their say with a Public Choice poll Winner.

“

A major landmark building prominent on Copenhagen’s skyline, the Maersk Tower nonetheless delivers on other levels as well. The conceptual development of its complex programme offers a fresh, more openly interactive research building typology. The response to its urban context is impressive with a curved form making it slim and elegant. And the project’s design qualities extend to exceptional detailing throughout and the innovative use of copper for the gently animated copper facades that define the building. A unanimous judges’ choice, the Maersk Tower is a clear Winner.

COPPER FOREST

10 COPPER ARCHITECTURE FORUM 43/2017

by Matti Kallio A symbolic, diagonally inclined box emerging from below ground and forming part of a new Metro station is defined by its ‘foliage’ of independent copper leaves.

An extension of the Helsinki Metro system, ‘Western Metro’ has been the largest infrastructure project in Finland since 2009 with 13 stations – each unique in character. One of three stations designed by HKP Architects, Tapiola Sports Park is dramatically announced by its Ticket Hall building. But this also connects to the local area with part of its inclined roof designed as a small amphitheatre serving events in the town square.

The design sought to create a fluent and secure interior for passengers with a clear progression from Ticket Hall via long escalators linking the platforms below. Project architect Jukka Ollikainen explained: “One of our main tasks has been to eliminate the feeling of being below ground, with sunlight and spacious views through the Ticket Hall playing a crucial role.

COPPERCONCEPT.ORG 11

RAISED COPPER FOLIAGE “Here, copper leaves, behind the diagonal glass wall, add interest and create a lively interplay of light and shadow changing with different lighting conditions – a kinetic beauty reminiscent of a forest.”

In the Ticket Hall, sunlight through the copper foliage creates changing patterns on the granite floor. A similar effect occurs on the ridged white facades behind the copper foliage grid system.

12 COPPER ARCHITECTURE FORUM 43/2017

The diagonal box Ticket Hall has a double façade. Its separate outer layer of copper ‘foliage’ comprises 445mm x615mm x 4mm leaf units of pre-patinated copper in 3 shades of blue/green. Each leaf is fastened to an acid-resistant stainless steel cable system, with 4 connectors at the cable intersections.

The cables form a parallelogram-like, level grid connected to a stainless steel frame with secondary support beams attached to the background wall. Cable ends have compressed turnbuckle mechanisms for tensioning the grid.

GOLD AND SILVER

by Chris Hodson Linking street and canal, this stylish Amsterdam housing development, replacing old industrial buildings, uses golden copper alloy and ‘silvergrey’ metal to acknowledge the area’s long history of shipyards.

14 COPPER ARCHITECTURE FORUM 43/2017

BOATHOUSES Strategically, Arons en Gelauff architecten’s design is organised into two bands of housing – each very different in character. Defining the street frontage are two brick blocks, either side of a narrow passage entrance, with the metal-clad canal-side housing beyond.

Together, they enclose a communal, green courtyard, which serves the waterside housing entrances, and includes semiprivate areas. The development is car free thanks to garage parking below the courtyard. The entrance route opens out into the courtyard and continues through to the canal. Here, it widens and steps down to touch the water and separates two staggered terraces of metal-clad houses.

COPPERCONCEPT.ORG 15

GOLDEN COPPER ALLOY These houses have deep floor plans and are set perpendicular to the water, inspired by traditional Amsterdam canal-side housing. Individual houses are highlighted by a narrowing top storey – a modern take on traditional steep gables – tapering from front to back and generating a private roof terrace alongside. A metal skin wraps up and over each house, encasing generous glazing to both elevations. This alternates between ‘silver-grey’ metal and a golden copper alloy, from one house to the next.

ARTEFACT

COPPERCONCEPT.ORG 19

In 2007 Sutherland Hussey Harris, in collaboration with Beijing based Pansolution, won the international competition for a new City Museum for Chengdu in Sichuan, China. Here, they explain the project, Inspired by the ancient bronze, gold and jade artefacts that form part of the museum’s permanent exhibition.

The building sits on the West side of Tian-Fu Square – a new central focus of Chengdu. It presents an East façade of commensurate scale and proportion to embrace and address the huge scale of this new square and establishes a strong formal relationship to it with a simple enclosing rectilinear profile. The building celebrates this relationship to the monumental public space by extending an internal promenade of public foyers and circulation behind the entirety of the veiled façade.

The new Museum extends to over 65,000m2 and includes exhibition space for Natural History, History and Folk, and an 800 seat Chinese Shadow Play Theatre, as well as a 1000m2 Temporary Exhibition space. A huge challenge was to provide 30m clear span exhibition halls with a structure capable of withstanding an earthquake measuring up to 8 on the Richter scale. Sections of the building also cantilever over the subway network tunnels. The solution was a rigid diagrid steel lattice that forms the structural shell.

It also envelops a new undercover outdoor public space - a monumental gateway through the building. Here, people can gather, cultural events can take place and even the local street market extends through to the square. This also creates an important connection between the C16th Huang Cheng Mosque, the most significant in South West China, and the main square.

A PRECIOUS SKIN OF GOLDEN COPPER ALLOY The long narrow site is exploited to give all the public areas a dramatic relationship with the new square via the East elevation. The remaining three façades then enclose the largely hermetic exhibition halls, represented as a giant crafted artefact in the city cloaked in a precious skin of golden copper alloy rigorously profiled to play with light, shade and texture whilst accommodating all the technical requirements for ventilation grilles. Aside from the East face this skin is ‘lifted’ to reveal glazing at street level, allowing a more intimate human scale and relationship with the interior.

22 COPPER ARCHITECTURE FORUM 43/2017

The skin forming facades and roof is expressed as one homogeneous material – a golden copper alloy which holds its colour well with age – but designed in such a way that it modulates and folds to present a variety of qualities. This is done through the tessellation of the skin profile and the arrangement of solid and perforated mesh panels, arranged to suite functional requirements inside.

The solid panels catch the sunlight dependent on their orientation and the mesh panels positioned where openings are required or where mechanical equipment needs to be ventilated. Meanwhile, the Eastern face is protected by a skin of perforated golden copper alloy mesh on a tension cable facade, coordinated with the folding geometry to maximise views out across the square. This also provides shading for the interior from the harsh glare of the Eastern sun and mediates the foyer spaces between outside glare and the dimmer environment of the exhibition halls.

COPPERCONCEPT.ORG 23

COMPLEMENTARY A World Architecture Festival Finalist in 2016, this apartment building in a prominent Sydney location is defined by its complementary, high quality materials including copper, as its designers SJB explain.

Commanding expansive views over Sydney Harbour, 10 Wylde Street is a 7-storey building of 22 apartments set in an urban fabric originating from early colonial grand residences and the first apartment buildings in Australia. This rich heritage demanded an architectural response that was sympathetic while contemporary and innovative.

24  COPPER ARCHITECTURE FORUM 43/2017

The design needed to be sufficiently rigorous to form a permanent, positive addition to the dense and complex urban fabric. High quality materials were essential in achieving this and we selected copper as a natural, sustainable material that will age gracefully.

The building envelope was defined by the previous building on the site and the resulting sight lines from adjacent properties.

The northern façade elevated above neighbouring buildings is characterised by its transparency and fineness of detailing, with thin metal window framing, slender columns and folded copper edge details. This open elevation is contained by the elongated roman profile brick masonry forms of the other three facades.

AWARD WINNING PROJECT

COPPER PERFORATED COPPER WINGS Distinctive copper ‘wings’ to the rear, south façade enable small triangular balconies to project from the monolithic masonry, screening them from direct sun and directing views towards the city and harbour. A subtle pattern of perforations in the screens provides solar shading and privacy from adjacent buildings.

26 COPPER ARCHITECTURE FORUM 43/2017

COPPERCONCEPT.ORG 27

Distinctive pre-oxidised copper cladding plays a unifying role in Glancy Nicholls Architects’ competition-winning design of the Chamberlain Hall complex for the University of Birmingham.

Set in a protected historic park, the new complex replaces 20th century buildings that proved unsuitable for modern, sustainable student accommodation and unfeasible to improve. Conceived as a landmark tower with three adjacent, linear ‘finger’ wings, the complex provides 726 student rooms, with communal facilities in the ground floor of the tower. The footprint of the new complex sits within the perimeter of the previous buildings, minimising impact on the surrounding parkland.

The architects’ ambition was to create a cohesive concept using materials and building forms to tie together the development as a whole. On the three ‘finger’ wings, brickwork matching local buildings acts as a ‘grounding’ material with pre-oxidised copper cladding as a striking, robust and high-quality finish above. The ends of the wings overlooking the park are highlighted by copper frames, projecting out to add solar shading.

UNIVERSITY LANDMARK Intended as ‘a landmark for the University within the wider city skyline’, the tower is based on a cranked X-shape plan with two elements, one 21-storeys, the other 17-storeys, linked by glazing overlooking two local landmarks. The taller element is brick, contrasting with its copper-clad neighbour.

The copper cladding on all the buildings incorporates perforated copper panels for natural ventilation to bedroom units and living spaces, opened internally.

A sleek dark box epitomising copper as a thoroughly modern material for today’s technology buildings.

The new Institute of Information Technology, Computer Centre and Archive building is a four-storey, square form set within a row of existing institutes along the green central axis – Konrad-Wachsmann-Allee. The plan is symmetrical with entrances on both south (the main entrance) and north sides, and open stairs to upper floors on east and west sides.

A ring structure places rooms on both sides of the corridors, organised around a rectangular courtyard. On the north and south sides, open lounges connect circulation spaces with the courtyard.

Vertically, functions are arranged according to the frequency of visitors with seminar spaces on the ground floor. These rooms are located directly from lobbies, which double as lounges and have direct access to the courtyard. Office spaces are located on the first and second floors. PC laboratories are directly assigned to these spaces and located across the hall, oriented to the courtyard. The third floor has limited access and houses high-security spaces for the University Computer Centre.

COPPER TO THE RESCUE

by Chris Hodson and Matti Kallio

COPPERCONCEPT.ORG 33

Designed by architect Olli Pekka Jokela and completed in 1992, Hämeenkylä Church in Vantaa, Finland was defined by its two main elevations, comprising a monolithic mass of pale yellow brickwork. But years of weather damage such as ‘frost wedging’ (the repeated freeze-thaw cycle of water within the masonry) or similar problems, perhaps made worse by the inclination of its tapered walls, left the brickwork beyond practicable repair.

The solution was a new external skin of pre-patinated copper, retaining the original architectural expression but with a fresh materiality and indefinite lifespan without maintenance.

34 COPPER ARCHITECTURE FORUM 43/2017

A NEW SKIN OF PRE-PATINATED COPPER A steel framework was constructed just in front of the failing brick walls, with pre- patinated copper cladding completely protecting the masonry from the weather while still allowing it to ‘breathe’. The new copper skin precisely follows the original inclined brickwork and fully accommodates the retained, original fenestration composition.

“

The pre-patinated copper provides a continuous surface to the monolithic form, relieved by close horizontal banding...

The impressive natural lighting into the building that characterises its original design and views out from the interior remain unaffected. The copper continues over a huge rectangular opening that announces the church entrance at the head of an approach ramp and the adjoining tower.

The pre-patinated copper provides a continuous surface to the monolithic form, relieved by close horizontal banding, referencing the brickwork beneath.

In the Kingdom of Saudi Arabia, a new bronzeclad visitor centre heralds the transformation of the Atturaif Living Museum into a world-class tourist venue and UNESCO World Heritage site, as Daniel Henderer of architects Ayers Saint Gross explains.

The Atturaif Visitor Reception Centre location is special as it is facing the ruins of the historic mud/adobe palace of the al Saud rulers of the First Saudi State. The rear of the building follows the Wadi Hanifa with solid stone walls, terraced and covered by an overhanging lightweight bronze roof.

CONTRASTING YET COMPLEMENTARY The Visitor Reception Centre will welcome guests to Atturaif and provide facilities, information, and guidance for visits to the 25-hectare site. Copper and copper alloy roofs and wall cladding are rare in Saudi Arabia but bronze was chosen here as a contrasting, yet complementary material to the historic mud structures and local stone walls, as well as for its natural patina.

The front of the building also has a bronze roof with deep soffit, which slopes upwards to promote views of the historic palace and site from the interior. The building’s solid stone walls, curving on plan, are connected by perpendicular bronze-clad walls and glazed openings.

COPPER FOR THE

by Chris Hodson

SINUOUS PLAN

Set in the deserts of Sharjah, United Arab Emirates, a multi-award winning visitor centre celebrates a Bronze Age archaeological site and features copper as part of a restrained palette of enduring materials.

The sinuous, curvilinear plan form terminates in a copperroofed reception and exhibition area, fragmenting into copper-clad folded elements spanning the café, with glazing opening out to the landscape. Copper proved to be the ideal material for the complex geometry, with careful detailing and fabrication by the cladding specialists, working closely with the architects.

The Mleiha Archaeological Centre is at the heart of an ecotourism project to protect the rich archaeology, environment and wildlife in the region, creating a coherent setting suitable for potential World Heritage Site status. Focused on and wrapping around the circular Bronze Age Umm an-Nar tomb – considered the most impressive grave building of the many ancient funeral sites in the area – the new building was designed by Dabbagh Architects and conceived as a double curve mirroring the spectacular Fossil Rock mountains nearby.

Given the historic importance and eco aspirations of the project, durability and sustainability were paramount in material selection. Principal architect Sumaya Dabbagh explained: “Alongside the regionally-sourced sandstone, we chose contrasting copper which is recyclable and will weather organically over time, thus enhancing its natural beauty. Apart from its obvious contextual relevance to the Bronze Age site, copper is exceptionally durable with low maintenance – essential in this harsh desert environment”.
