Copper Architecture Forum 2012

Copper Architecture Forum 33, november 2012

Copper Architecture Forum er en del av den kontinuerlige kampanjenEuropeisk kobber i arkitektur. Magasinet har et opplag p 25.200 ogutgis to ganger i ret.Magasinet leveres til arkitekter og byggesakkyndige i hele Europa p eng-elsk, tsjekkisk, dansk, fnsk, ransk, tysk, ungarsk, italiensk, norsk, polsk,russisk, spansk og svensk.

KobberdifferensieringI denne utgaven har vi samlet en eklektisk blanding av nye bygningerhvor kobber og kobberlegering spiller en sentral rolle i det arkitekto-niske uttrykk. Den kan betraktes som en typologisk rundreise som av-dekker en kt di erensiering ved bruk av materialet og nye teknikkerblant designere av alle typer bygninger.

Opp atningen av kobber har endret seg i takt med dens rolle i modernearkitektur, noe den ortsetter gjre. Kobber brukes selv lgelig ort-satt p de typer bygninger som materialet har en historisk tilknytning til. Men kobber brukes o te i en moderne sammenheng, som kapelletp slutten av denne utgaven (s. 36-38) er et eksempel p en konisk trommel som strekker seg gjennom midten av dens tilhrende skole,med inspirasjon bde ra kirkekupler og -spir. Kobbertak er ogs isentrum or vrt rste prosjekt, et atrium i et stort kon eransehotell(s. 4-76) som er ormet som en dekonstruert gylden stjerne, som visermaterialets muligheter or innovative og nyskapende ormer, bde inn-vendig og utvendig.

Kobberets unike ormingsmuligheter er tatt til nye hyder med de dra-matiske kurvene i et klubbhus ved havet (s. 8-9), som ble muliggjort vedbruk av databaserte modelleringsteknikker, som gir mulighet or strredesign rihet. I motsetning lger ormen unksjonen p en rednings-skytestasjon (s. 12-15) som ble designet med henblikk p artyet denhuser, og som beskyttes av kobber mot de hardeste miljer et de-

sign som har vist seg kompetent til bli gjentatt andre steder. Miljvernde nerer ogs bronse- og glassinnhegninger or to eldgamle runestein(s. 28-29), som har en enkel, skulpturell kvalitet.

ydelig de nerte ormer karakteriserer ogs Marlow Teater (s. 16-19)en typologi som tradisjonelt er orbundet med kobber. Det samme kansies om o entlige biblioteker, men i Seinjoki (s. 32-35) respekterer en navdeling i Alvar Aalto-senteret dets ikoniske kontekst, samtidig som dedistanserer seg med en kobberbelagt overfate. Et annet bibliotek Dept-

ord Lounge (s. 24-27) utvikler seg til en ny, pen kommunal bygningsom uttrykkes av gjennomsiktigheten av de gullegerte asadene.

Den typologiske variasjonen i kobber utvides ytterligere med en abstrakbehandling ved bruk av fere materialtyper, or live opp asaden p et elers typisk parkeringshus (s. 20-23). Og en midlertidig bygning (s. 10-11- en annen type bygning som ikke o te orbindes med kobber - r spesbetydning med et ullstendig belegg av gullegering. il sist minner mellomstort tilbygg (s. 30-31) oss om at kobber ogs kan til re bestemkvaliteter sammen med andre materialer.

Kobberarkitektur er ortsatt under utvikling, drevet av arkitekter og dereentusiasme or materialet og dets muligheter. Og med din hjelp skavi ortsette vise de beste eksemplene her og p nettsiden www.coppeconcept.org.

Clarion Hotel i Trondheim er ett av Skandinavias strste kon eranse-hoteller, og det s trste i Norge. Space Group, arkitektene bak desig-

net, brukte en strategi hvor distinkte plateliknende vrelsesfyerble tilpasset or gi gjestene en per ekt utsikt over havet, landskapetog byen. Denne vridningsteknikken pner det sentrale atriet og ska-per et tredimensjonalt omrde med en kompleks, asettert tak ormen dekonstruert gullstjerne - som strmmer nedover. Bygningen eret dramatisk syn ra alle vinkler, men spesielt oven ra, hvor de festegjestene ser den rste gang nr de ankommer med fy.

Et hotellkompleks i Norge orsker orvandle kon eranse-opplevelsen med en dramatisk ny vri p et moderne atrium,

En splintret gullstjerne strekker seg ut mellomhver blokk og binder dem sammen

Hardfre materialerDesignet viser en hard r bruk av ma-terialer mellom de orskjellige elemen-tene. Den enorme teksturerte og mrkekassen i hovedkon eransesalen str isterk kontrast til de glassdekte sove-romsblokkene med hvit silketrykk, somer opplst or skape vinduer med enmyk, skyliknende e ekt. Den splintredegullstjernen, som er ormet av en kob-

berlegering med aluminium og sink,strekker seg ut mellom hver blokk ogbinder dem sammen.

Prosjektets arkitekt, Jens Niehues,kommenterte: I kobberlegeringen ant vi et materiale som ga oss mulighet til lage et design med en levende overfate som gjenspeiler Stjernens naturlige

unksjon og gir den en detaljert, gyldennyanse. I tillegg til realisere vre kon-septmessige mlsettinger, skulle ma-terialet naturligvis ogs overholde vre tekniske ut ordringer i det krevende kli-maet p vestkysten av Norge.

Kobberlegeringen vil ikke utvikle en bleller grnn patina over tid, selv i dette harde klimaet, men den vil i stedet or-

bli gyllen. Materialets karakteristikker danner loddrette, vannrette eller skrskjter som remhever Stjernens tre-kant orm. I tillegg kunne materialet bearbeides or gi det en skarp kant,med rene linjer p takrennene. Valget av gylden kobberlegering var helt riktig or den erdigstilte bygningen.

The Hamilton Island Yacht Club and Villas p WhitsundayIslands, som er en del av Australias Great Barrier Ree ,ble designet or skape en visuell e ekt - ikke barenr den ses ra land eller vann, men ogs ra lu ten, hvor ra

mange av gjestene ankommer. Arkitektene orestilte seg enbygning som kunne orbinde moloen samt gjenspeile de mari-time elementene og seilsportkulturen. Designprosessen rtetil en skulpturell sammensetning av kobberbelagte ormersom minner om vindblste seil, spinnakere, kjler og om vin-dens, tidevannets og havstrmmenes vir vlende kre ter.

Seilklubbens sentrale kjerne er et overbygd vind ang, eller pi-azza, som rer inn til de orskjellige private og o entlige rom.Med en gradvis endring av taknivene og en prosesjonsrampe,

res bygningen ut i en l tet platt orm som henger ritt overvannet. Klubbhuset rommer asiliteter som bl. a restauranter,barer, et auditorium, kon eranserom, treningssenter, tre-

ningsbasseng, leserom og utstillingslokaler. Den integrertebebyggelsen byr ogs p 35 eneboliger.

Komplekse kobberbelagte formerDe komplekse blad ormede takene p klubbhuset stttesav tre-syler av stl, hvor grenene mter det buede taket ifere vinkler. Det ble utviklet et slyngverk av stl som kunnestrekke seg opp til 16 meter og henge ritt i 11 meters hyde,og dermed over re sidebelastningen til midtveggene. Detteminimerer den strukturelle dybden mellom takbelegget ogtakene, som kreves av arkitekturen. Det orenkler dessutenoppbygningen og takkonstruksjonen. Kobber ble valgt pga. sin

holdbarhet, sine visuelle karakteristikker, og selv lgelig ogspga. sin unike evne til belegge komplekse tredimensjonale

ormer.

BIM(Building Information Modelling)BIM viste seg vre avgjrende or det detaljerte designet

og selve konstruksjonen av Hamilton Club - spesielt kobber-takene. P grunn av de komplekse ormene var det behov oruttallige seksjons- og detaljtegninger or vise hvordan kom-ponentene passet sammen. Data ble eksportert til andre somvar involvert - bl. a. til stlprodusenten, som arbeidet ut ra dendigitale modellen.

Tilstedevrelsen av den komplette digitale modellen avbygningen p stedet betydde at byggearbeiderne kunne se tre-dimensjonale tegninger etter hvert som bygningen tok orm.Tverrsnittbilder av de orskjellige komponentene var ogstilgjengelige, som hjalp alle med orst nyaktig hvordan byg-ningen var konstruert. Men BIM bestr av langt mer enn CAD

og tredimensjonale tegninger, da det inneholder komponenterog materialer med modellattributter, slik som omkostninger,miljbevarende egenskaper og vedlikeholdsintervaller.

Formlet med BIM er skape en komplett digital modell ordesign, produksjon, konstruksjon og bygnings orml med hjelp

ra alle deltakere. Det hjelper arkitekter skape et mer bre-dyktig, nyaktig design med rre eil og mindre slsing. Hvisman kan se en simulert utgave av resultatet, r man ogs enbedre orstelse av kostnadene, planleggingen og miljpvirk-ningen.

Det orventes at bruken av BIM vil ke betraktelig ved design av

alle typer bygninger. Det gir arkitekter en mulighet til prvenye uttrykks ormer - og kobber er ideelt or realisere inno-vativ design.

STJERNESKUDDEn hypermoderne intervensjon bekledd med gyldenkobberlegering markerte meget passende utstil-lingen Golden Splendour: Mediaeval Treasure Art inWestphalia, som ble holdt i den tyske byen Mnsterdenne sommeren.

P lassert p den sentrale Domplatz, var denne midlerti-dige paviljongen en moderne kontrast til den historiskebykjernen, hvor den orente utstillingsomrder i mu-seet med Cathedral Art Chamber. Paviljongen var et resultatav samarbeidet mellom Mnster School o Architecture ogarkitekt rmaet modulorbeat. Under ledelse av arkitekteneMarc Gnnewig og Jan Kampsho , utviklet et team opprinne-lig bestende av 33 studenter orskjellige designutkast.

Den gylne lsningTil slutt valgte en komit den gylne lsningen, en stjerne or-met bygning med et stil ullt kryssdesign, karakterisert av degylne kobberlegerte asadene. En midlertidig paviljong i or-bindelse med en kunstutstilling er ikke noe ny tt i Mnster. For

em r siden skapte modulorbeat en liknende bygning, hvor det

ogs ble brukt kobberlegering.Med unksjon som etlevende verksted, ble paviljongen bruktil kunstundervisning i orbindelse med utstillingen. Sett gjen-nom endeveggene av glass, var dette minimalistiske og enkledesignet gjenspeilet i interiret. Den brende strukturen, be-stende av massivt eller krysslaminert treverk, var helt na-kent, som ga overfatene p gulv, tak og vegger et ensartet,lyst treskjr - sammen med de tte arbeidsbordene som varsamlet av prosjektdeltakerne selv.

The new structure sits on the ootprinto the original building: well-positioned

or li eboat launching in bad weatherbut also reducing the environmentalimpact o the scheme. At rst sight,the wave pro le o The Lizard li eboatstation appears symbolic o its coastalposition - but orm really does ollow

unction and refects the arrangemento internal accommodation, ocused on

the li eboat itsel . Essentially, the ves-sel is mounted on a tipping cradle, whichtilts to align with the slipway, enabling itto be launched and recovered allowingvolunteer crews to reach those in trou-ble as quickly as possible. The outwardraking wall to the side o the buildingrefects the demand or accommodationat the main foor level with ast accessstraight onto the li eboat.

by Chris Hodson

The new RNLI li eboat station at The Lizard is protected by a curved copper skinto withstand the extremely aggressive coastal environment o its unique locationon Englands most southerly point. The RNLI charity saves lives at sea. Its volun-teers provide a 24-hour search and rescue service around the United Kingdom andRepublic o Ireland coasts. The buildings design was developed rom a previousproject, also by PBWC Architects, in Padstow, Cornwall. It is a direct response tothe speci c technical demands o the new RNLI ast slipway type li eboat housedthere and is an exemplar or uture buildings o the type in other locations.

Weather-tight DesignAll accommodation is located on oneside o the building, which allows theheated and serviced zones to be e -ciently grouped together and all ventila-tion and lighting needs to be met with astrip o ribbon glazing or punched win-dows within the raked wall. The curveo the roo then encloses the minimumvolume required or the li eboat and cre-ates a simple orm that lends itsel toa single fexible roo nish. The designaims to maximise roo area while mini-mising penetrations to ensure a robust,weather-tight nish.

Copper ChoiceThe selection o metal roo ng was a logicalprogression rom the development o the dis-tinctive, wave-like, curved orm. PBWC projectarchitect Cian Spowart commented: A ter the Padstow project, we reviewed the roo ng ma-

terial and system or The Lizard li eboat sta-tion. Here, copper was selected or its durabili-ty and capability o withstanding the aggressive c oastal environment, including the possibility o debris being thrown up rom the sea. In ad-dition, the aesthetic choice o copper over other metal roo ng was driven by its characteristic weathering over time to give a rich green patinacomplementing the aqua blue hues o the localcoastline.

The Marlowe is, in ormal terms, a complexpavilion. It sets up a dynamic relationship

with its viewers, giving di erent architec-tural and urban emphasis depending romwhere in the city it is viewed. At streetlevel, its architecture is ordered by an8m high colonnaded loggia in white castDolomite stone, which orms a portal tothe multi-level glazed oyer and sets up acivic elevation to the Friars, an importanthistoric street within the city. The oyerconnects all the major internal spaces tothe riverside terraces and pathways and isseen as a crystal ribbon by day trans orm-

ing into a blade o light by night. New viewso the roo tops o the historic city and itscathedral open up rom the main stairsand upper levels.

The colonnaded loggia mediates be-tween the street scale o the Friars (thestreet which the Marlowe aces) and thenecessarily larger orms o the two thea-tres and the fy tower. The colonnaded

overhang also provides shelter to thesouth- acing oyer rom high angle solar

gain and provides an architectural unity tothe composition. A new public square hasbeen created by setting the Marlowe back

rom the existing street edge.The fy tower o the old theatre, widely

regarded as an eyesore, was the secondtallest structure in the city a ter BellHarry, the medieval Cathedrals principaltower. The new Marlowes fy tower is 9mtaller than its predecessor, allowing it tobe sculpted to create a pinnacle orm ac-ing toward the Cathedral, adding accent

and silhouette to the citys skyline. Itsorm can be seen as a prominent symbol

o secular architecture within the historiccity whilst ensuring that Bell Harry re-tains its predominance. From the east, thefy tower dominates the street scene an-nouncing this major new cultural projectwithin the city.

Materiality and ContextualityThe composition and massing o the new

Marlowe is rooted in its context. The build-ing is seen to step up in scale gradually

rom a lower-rise street scale along theFriars, up to the larger volumes o themain auditorium and fy tower beyond.Materiality is also determined to a largedegree contextually, in that it borrowsthe hues and tones o the Canterburytownscape. The reconstituted stone col-onnade takes its cue rom the whites andcreams o buildings in the city, whilst thepre-oxidised brown copper cladding ech-

oes the colour and hues o the nearby tiledroo tops. Materials are used to createsomething highly contemporary, whilst atthe same time complimentary to the con-text in terms o texture and colour.

Copper plays a distinct role in the compo-sition o the theatre overall, surrounding

the volume o the studio space, which me-diates between the entrance scale and thelarger volumes beyond. The studio theatreis raised 4 metres above the ground; a vol-ume wrapped entirely in copper. As such itis almost at roo level o the surroundingbuildings hence the relationship betweenthe reddish brown copper cladding withthe colouration o Canterburys roo scape.The underside o this volume orms theinternal so t to the restaurant space cre-ated beneath. The raising o the volume

allows the restaurant to be slid beneathat oyer level, giving views to an adjacentexternal terrace and the banks o the RiverStour.

Copper StudioHorizontal standing seam bands o varyingwidths (using trays o 230 mm, 430 mm

and 600 mm) wrap continuously around thestudio volume, with olded birds mouthcorner details enabling the horizontalityto fow continuously around all sides. Atthe junction with the main glazed curtainwalling, the copper runs cleanly through

rom outside to inside, with internalopenings ormed to create a connectionbetween the studio theatre bar areas andthe main entrance oyer.

Though the rationale in each case isdi erent, the use o copper at the Marloweechoes our previous work at the UnicornTheatre in London, completed in 2005 (UKAward Winner o the Copper in ArchitectureAwards 13 in 2007).

ANIMATINGTHE UTILITARIAN

Forming part o the Hub development at Nottingham RailwayStation, this 6-storey structure accommodates 950 car spaces.The 112 m long building is sandwiched between the railway tothe north and the busy Queens Road to the south with olderbuildings beyond. Architects Leeds Studio developed an originaldesign by another practice, BDP, ( ollowing a success ul bid byVINCI Construction UK) adding an array o horizontally bandedvertical copper panels to trans orm this typical parking building.The panels create an architectural language and are continuousover curtain walling as well as conventional open car parkingdecks, only being broken by the concrete li t core on the WestElevation.

The palette o copper sur aces at Nottingham includes solidgreen pre-patinated copper and a variant with less intensepatination, revealing some background material. Standard mill

nish and light brown pre-oxidised copper were also used, to-gether with an alloy o copper and aluminium with a long-lastinggolden colour which provides distinctive highlights around thebuilding.

Although creating a random, abstract eel, arrangement o thepanels is based on a limited modular language with three panelwidths: 210 mm, 420 mm and 840 mm, and spacing between o :105 mm, 210 mm and 420 mm. Panels are generally 2870 mm

high with some reduced to 1470 mm crowning the top o thebuilding and where the base o the cladding is raised up.

A Mosaic of ColourThe composition gives a mosaic o colour that sits in clearly de-

ned horizontal bands along the length o the building, breakingup the subservient concrete rame - typical o multi-storey carpark buildings - and curtain walling. The e ect is particularlyanimated on the two long elevations, especially when viewed

rom moving trains or cars. In addition to the layering o ma-

terials, the colour choices are carried through in the design torepresent di ering aspects o the location.Project architect Antony Hall explained: The copper panels

to the North are predominantly in green shades and re er to the modern aspect o the adjacent railway. The panels on the Southare predominantly in traditional brown copper shades to re er-ence the brick heritage warehouses and other structures liningthe conservation area opposite across the busy road. Key view-points ormed in locations around the building are highlighted with the golden coloured copper alloy. Vertical circulation ele-ments are also highlighted in the same manner. There is a de-signed progression o copper colours running around the whole

building, beginning and ending at the West Elevation li t sha t.We have also anticipated the natural changes to copper in the environment.

Multi-storey car park architecture is generally constrained byvehicle circulation and other technical demands, reducing it toa utilitarian level. But the numerous permutations of surfacesand forms available with architectural copper today offer de-signers exciting possibilities to treat bare facades as a blankcanvas. The Nottingham project is an inspiring example of thisapproach.

The brie rom the London Borough o Lewisham was to create the centrepieceo their regeneration o Dept ord Town Centre a new civic ocus or Dept orThis was to include a state-o -the-art public library, including a resource centreand council services centre called the Dept ord Lounge with a new building

or Tidemill Primary School, relocated rom its existing site.

Our scheme, completed in December 2011, created rom the bare bones o thisbrie , a highly innovative mix o co-located uses on a single site: the completedcomplex houses acilities shared between the new primary school and the wholecommunity via the Dept ord Lounge. To this mix we also added apartments overartists studios and exhibition space Resolution Studios.

The design was also driven by the aspiration to restore to Dept ord somethingo the grandeur o its past, r st as a hub o shipbuilding and later as the locationo the rst railway station south o the River Thames. Now the golden Loungebuilding sails galleon-like above Gi n Square, a new public space or Dept ord.Tidemill Academy lies within an urban oasis, sheltered on one side by the Dept-

ord Lounge and on the other by Resolution studios, with classrooms groupedaround a green and lea y central play space. And new homes look out over thehistoric St Pauls Church and the railway line leading over the r iver.

School and Community UseShared acilities o Dept ord Lounge include a roo top sportspitch, a fexible suite o assembly spaces and a dining hall andkitchen, which are available or hire. All these acilities are lo-cated on the upper foors o the Lounge building and all elementshave separate access points both rom within the school and

rom the public realm. This enables the school to have sole useo the shared acilities during the school day. Then, out o schoolhours, the shared acilities orm an integral part o the Dept ordLounge and are open to the whole community.

INTERVIEW

CH: How did your selection o the golden cop-

per alloy come about and did you look at other materials?

HK-B: We wanted a material that relatedstrongly to the conceptual meaning o theDept ord Lounge on a series o levels. It wasto be seen as a landmark a civic ocus orall ages and cultures. Initially timber cladding was considered, relating to Dept ords nauticalpast but timber requires maintenance. Wealso sought an inspiring material, with re ec-tive properties that would give the building a jewel-like quality set against its main streetcontext. Tis meant considering various met-als including copper. It also led to the idea o expanded metal meshes or per orated sheets. We elt that the per orated golden copper al-loy cladding o ered multiple meanings on a conceptual level. Te gold sur ace symboliseswealth across all cultures, welcoming andbringing together a diverse community intoa building that o ers a wealth o knowledgeand services.

CH: What about sustainability and environ-mental considerations when choosing the aade material?

HK-B: Copper and its alloys have sound sus-tainable credentials with exceptional durabili-ty and li espan. Te weathering characteristicso this copper alloy are important: the mate-rial is virtually maintenance ree and providesa sur ace that will change very little over time, which means it wi ll retain its crisp jewel likequality.

CH: What were the design intentions behind this

dramatic statement o a transparent golden skin? HK-B: Te wrapping o the gold cladding aims to uni y the buildings complex range o

unctions, binding them together.Contextually, it relates to various points o Dept ords rich history, including its growth

rom a small shing village into the Royal Na-val Dockyard with links to HMS Discovery,Sir Francis Drake and Captain James Cook.So, the wrapping has multiple unctions andre erences. From a distance the golden ormappears solid but close-up reveals itsel astransparent and light-weight, oating aboveits glazed base. On a unctional level, the wrapping provides solar shading to the largeareas o glazing, while also allowing suitablelevels o light in. CH: How were these intentions realised on the building with the pierced copper alloy panels and how did the detailed design develop?

HK-B: Te panels are rigid olded cassettesthat provide sharp and clean joints betweenpanels, rather than something that wouldbuckle and distort. Te nautical re erences

continue with the setting-out o the panelsin a stretcher bond pattern like historic tim-ber hull construction in ship-building. Teper orations are kept back rom the edges tohelp express each panel individually whileretaining rigidity. We explored various per o-ration shapes, rom square to raised diamondpatterned with a cheese grater appearance,

and settled on simple circular holes, again ar

ranged in a stretcher bond pattern. Di erentlevels o per oration were also considered,the transparency o the wrapping adds another dimension with the play o light. Te build-ing responds to its uses and environment,continually changing with light conditionsthroughout the day and into the evening, be-coming more or less revealing suggestindiscovery. Te level o transparency increase with distance away rom the solid ships bowcorner, with its large symbolic window, gradually blurring solid and void.

CH: How was the light, foating eel o the piecopper alloy skin achieved in structural terms

HK-B: Initially, the cladding was to be suspended on rods rom a ring beam. But due tothe buildings subtle shi ts o orm both the vertical and horizontal planes additionalsupport was required, depending on locationaround the building. Te solution was to xsteel brackets back to the main building struc-ture at the top and bottom o the wall. Tesethen support a rame and suspension rods, to which the copper al loy panels were xed. Additional structure and stays were incorporated where the golden wrapping pulled urtheaway rom the building, reducing movemen

rom wind loading. Te transparency o thepanels also o ered urther opportunities texpress the structure behind with honesty.

Te Jelling runic stones mark Denmarks transition to Christi-anity in the year 965 and the monument is also known as Den-marks birth certi cate. Inaugurated in December 2011, theproject is based on the winning competition design by NOBELarkitekter. Our principal aims were to protect the runic stones

or the uture and, at the same time, provide an architecturalcomposition allowing spectators to get very close to them.

Sheltering Bronze Hands

Deceptively simple bronze and glass structures provide a safeenvironment for preserving two unique 10th century runicstones designated a UNESCO World Heritage site - at Jell-ing Church, Denmark. But these interventions go well beyond conservation, seeking to transform the visitor experience, as

architect Erik Nobel explains.

Te design orms a stylised dialogue between the two stones which represent the rst two kings o Denmark Gorm andHarald Bluetooth. Te bronze angles orm one gable and theroo or each structure, while the other aces are ully glazed. objective was to accentuate the runic stones curved orms bcontrasting them with the straight lines o the coverings whichin a metaphorical sense, hold protective hands over them. Tecast bronze contrasts with the texture o the ancient stones anhighlights their grey and reddish granite sur aces.

Te requirement or creating a controlled climate around thestones was a central consideration in the development o the pro

ject. Our consulting engineers rom Rambll designed a speciheating and ventilation system which ensures a rost- ree climaround the runic stones. Arti cial lighting has been discreetladded using specially designed bre-optic light sources, whicare integrated in the roo structure.

Te lighting emphasises the stones runic scriptures and visualmoti s, and accentuates their shapes. Juxtaposed with the angular bronze orms, the arti cial lighting creates a completely ne

We were appointed to care ully restore elements o the existing architecture creating a contemporary yet sensitive addition tothe rear. o the ront o the property the new addition appears asa simple copper box peeping above the layers o existing greenglazed tiles o the existing home.

In the re urbishment, living and entertaining space is providedat ground oor through the introduction o a predominantly sin-gle storey glazed element. At rst oor, a layered copper and oak

orm appears to delicately hover. Set on a shi ted geometry toacknowledge the existing building orm, this creates a series o overhangs, cantilevers and canopies to shelter its occupants romthe persistent Welsh rain.

Copper over timeTis thoroughly modern addition to an existing home inCardif, South Wales discussed by Kristian Hyde o Hyde+ Hyde Architects combines copper with oak and glass inits care ully conceived design to anticipate change.

Te original house is quirky but beauti ul. Te unknown ar-chitect has put a great deal o e ort into the detailing, someo which is very play ul. Tere is a certain humour about someo the spaces that continue to make our clients smile. Te new addition responds with a singular oak clad curve at rst oor

which mimics the geometry o the existing curved glazing othe main house. Tis is introduced to turn the new additioninto the main private garden at the rear.

Copper was chosen as a suitable material or acades and otherdetails to converse with the existing green glazed roo tiles othe existing dwelling. A ter a decade it will begin to relate incolour and tone to the existing tiles nearby, its salmon pink andrusset brown tones will be gone orever. Tats the beauty o copper, its timeless and orces us to think about buildings intime. Coppers material character helps buildings eel as i theyhave always been there.

The Centre displays Aaltos master ul touch, rangingrom the areas town planning to the smallest door

detail and is an invaluable cultural asset which givesthe whole town its identity. Five Aalto buildings makeup the Centre: the City Hall, State O ce Building,Theatre, the Cross o the Plains Church and the OldLibrary.

DIALOGUE BETWEEN OLD AND NEWBuilt in 1965, the Library needed a modern extensionto meet todays demands and JKMMs design, calledClover, won the competition or the project. The aimwas to create dialogue between old and new. The newlibrary respects the protected cultural environmentbut, at the same time, takes pride in contemporaryarchitecture. One o the objectives o the design was

to nd an inter ace with the typical characteristics oAlvar Aaltos architecture without imitating it.

The Finnish town o Seinjoki hosts the mostextensive cluster o buildings designed by AlvarAalto in the world. Asmo Jaaksi o architectsJKMMexplains his practices approach to design-ing a new addition to this hallowed Aalto Centre.

VARIED INTERESTING SHAPESThe new library stands separate rom Altosoriginal, although connected by an under-ground link. Division o the building intothree sculptural units was an important de-

cision to be able to blend the large buildingvolume with the surrounding townscape.This generates varied, interesting shapeswhen viewed rom di erent directions. Theexposed boarded- ormwork concrete in-teriors are punctuated by care ully placedwindows and larger glazing o ering con-trolled views o the Centre. The view romthe glazed wall in the main library hall isdominated by the highlights o the area: thebell tower or the Cross o the Plains Churchand the an-shaped acade o the original

Aalto Library. The heart o the building isthe wide staircase, intended or di erentevents and as an in ormal meeting place,which leads to the collection departmentson the ground foor and through the con-necting underground corridor to the AaltoLibrary.

LIVELY AND VIVID SURFACEThe external skin o the new library isdominated by copper. The darkening pre-

oxidised copper sets the new library apartrom the whiteness o the surroundingbuildings. Copper is not a new material tothe area but in the Aalto Centre it is mainlythe roo s that eature the materials beauti-

ully patinated green sur aces. In the newlibrary, copper has been used comprehen-sively across acades, plinth and roo s creating a single-material skin.

A special shape o copper shingle was spe-ci cally designed or the acades to give thebuilding a highly individual, lively and vividsur ace. In some situations, the shinglesur ace is ormed into ventilation slots toaccommodate air handling. Copper is alsoused to orm vertical grilles and as a door

acing to maintain the material continuity.

CoPPER CloSE-UP

Covering the Cone with Copper A key element o the concept was or thechapel to appear monolithic both with-in the space and externally as it reachedthrough the atrium roo . Te originalproposal was or timber cladding, but thedesign team recognised the difculty o ensuring the internal and external elements

would weather consistently. Bright copper was selected with a special, anti-weathering coating to minimise any change as the sur-

ace aged.

Shingles were chosen to deal with the com-plex orm that curves in both plan andsection. Te cladding o the chapel wasundertaken with real cra tsmanship by NDM, the copper shingles gradually re-ducing in size to accommodate the conicalshape. Te orm was computer modelled,as the size o each row o shingles had tobe calculated to suit the diminishing diam-

eter.
