La Regeneracin

www.copperconce

Este nmero est dedicado al ingenio de los arquitectos para regenerar

los espacios en los que vivimos y trabajamos, para preservar y adaptar

los paisajes urbanos y los edicios existentes dndoles nuevos usos de

orma sostenible y ahorrando recursos. Aunque esto tambin lleva con-

sigo un desao para los diseadores, teniendo que desarrollar su par-

ticular interpretacin de la historia dentro del contexto del siglo XXI.

Los proyectos que presentamos en este nmero muestran dieren-

tes ormas de arontar este desao que van desde las intervenciones en

estructuras existentes, hasta nuevos edicios que interactan con los

antiguos para remodelar el paisaje urbano. Sin embargo, todas ellas

tienen un nexo en comn: las dierentes y numerosas posibilidades ar-

quitectnicas que orecen el cobre y sus aleaciones.

Nuestro tema de portada es una clara muestra de ello. En este

caso, las ormas revestidas de latn se integran dentro del tejido urbano,

aportando un entorno renovado a la Catedral de Lund. Con un estado

inicial luminoso y moderno, las supercies de bronce pronto se irn

oscureciendo y evolucionarn, adquiriendo una calidad atemporal. La

misma calidad se muestra en las intervenciones con cobre preoxidadode una histrica villa italiana (p 18-21), crendose ejes de circulacin

adaptados a la nueva uncin hotelera del edicio.

La naturaleza eterna y permanente del cobre se ve reorzada por

los elementos de latn incorporados a un castillo espaol (p 34-35). En

este caso, no se busca una reerencia literal sino una esttica abstracta

totalmente acorde con las ruinas del castillo. Este enoque guarda para-

lelismos con el uso del cobre para expresar las nuevas adiciones de una

tpica casa rural de Luxemburgo (p 26-29). En una escala ms grande,

la nueva ampliacin de un almacn restaurado en Londres (p 12-15),

utiliza un revestimiento de bronce para refejar la cubierta a dos aguas

del edicio original, creando una composicin unicada. Un enoque

similar se utiliza para la ampliacin de una iglesia de Londres (p 32-33).

La relacin entre edicios modernos y antiguos tambin se explora

con la nueva casa de campo Orangerie en Holanda (p 8-11), incorporan-

do un pabelln acristalado con una cubierta verde de cobre prepatinado

que establece un vnculo con la casa original. Un enoque ms literal se

adopta en una nueva planta de tratamiento de aguas en Varsovia (p 22-

25), con una clara reerencia a las ventanas y los tejados a dos aguas de

sus vecinos del siglo XIX. Aqu, el cobre juega un papel ms tradicional

como material de cubierta. ambin consideramos el papel desempe-

ado por el cobre de dierentes ormas, para regenerar algunos edicios

poco sugerentes del siglo XX (p 16-17 y p 30-31). erminamos como

empezamos, con otro ejemplo de una intervencin de cobre que remo-

dela el entorno urbano de su husped ms antiguo en esta ocasin,

los antiguos baos pblicos en Tiene, Italia (p 36-38). Se trata de unedicio redundante al que se le da una nueva vida como centro juvenil

denido por la adicin de un caparazn de cobre.

Esperamos que disruten de este viaje por todos estos proyectos

inspiradores, donde el cobre acta como un catalizador para la regenera-

cin urbana y la invencin arquitectnica.

El diseo de la arquitecta Carmen

Izquierdo, desarrollado a partir de

la propuesta ganadora de un con-

curso, se centra en una intervencin

totalmente contempornea de latn

y vidrio que serpentea entre varios

edicios antiguos, envolvindolos

en el esquema global. La achada

de la calle Kyrkogatan incorporauna marquesina de latn como una

continuacin del plano de la cu-

bierta del edicio adyacente, con un

patio de entrada debajo. El edicio

contina en Kungsgatan y luego se

extiende hacia la catedral, con el

auditorio terminando en una ventana

con orma de embudo que simbli-

camente se levanta hacia las torres

histricas.

Aadiendo a los Estratos Histricos

Carmen Izquierdo comenta que la

idea era crear un edifcio contempo-

rneo que aadiese una nueva capaa los estratos histricos que conor-

man el centro de Lund. El nuevo edi-

fcio se esuerza por armonizar con

el paisaje urbano de una manera

natural mediante la captura

de la escala y las lneas de los edi-

fcios existentes. El lema de la obra

ganadora ue Portal & Atrium y las

ambiciones de la propuesta original

se pusieron en prctica con un pro-

grama completamente nuevo en el

diseo fnal.

El latn... un material naturalque aporta una superfcie rica y

vibrante, que evoluciona conel paso del tiempo inte-grndose en el paisajeurbano.

En el interior, el espacio dominante es el vestbulo de entradaconectado con la plaza de la catedral y Kungsgatan. Con suatrio de doble altura, es un agradable lugar de encuentro utili-zado para recepciones, exposiciones y ccteles, dominado porlas ocinas de la planta superior. Aqu, la solidez de las pare-des de hormign con la textura de la madera natural contras-ta con la transparencia creada por las mamparas totalmenteacristaladas. El expresivo auditorio se ha diseado como unespacio nico, con vistas a los chapiteles de la catedral desdesu distintiva ventana trapezoidal con orma de embudo.

Una Puerta de Entrada para los Visitantes

Carmen Izquierdo aade que el edifcio crea interesantes es-

pacios secuenciales exteriores e interiores y ser una puerta

de entrada para los visitantes de la catedral y un oro para el

debate y el estudio en proundidad. El nuevo edifcio tiene un

diseo simple pero expresivo que interacta con el paisaje ur-

bano circundante a travs de sus ngulos y declives. El latn

se eligi para la piel externa del nuevo edifcio por tratarse de

un material natural que aporta una superfcie rica y vibrante.

A medida que el material evoluciona con el paso del tiempo, el

edifcio se integrar poco a poco con el paisaje urbano.

En su estado nuevo y br illante, el edicio transmite su ener-ga y exige una respuesta de los visitantes. Sin embargo, a

medida que el latn se oscurece de orma natural con el pasodel tiempo durante los primeros aos, adquirir una calidadms sutil e intemporal. Las ormas y el movimiento del edi-cio consiguen preservar las importantes vistas histricasy, al mismo tiempo, crear nuevas perspectivas. Tambin segeneraron espacios pblicos ms ntimos y var iados, tanto al-rededor como dentro del nuevo edicio. En su inauguracin elao pasado, el obispo Antje Jackeln describi acertadamenteel nuevo edicio como el abrazo prolongado de la catedral.

Por encargo de SAS Institute Inc., desarrollamos un plan para

su sede en los Pases Bajos. SAS (antes conocida como Sta-

tistical Analysis System) tiene su base en una gran casa de

campo histrica en Huizen. Cuando la empresa contact connosotros, la casa contaba con una deteriorada ala de pro-

longacin de principios de la dcada de 1960. La esencia denuestro concepto de diseo radica en la sustitucin de esta

prolongacin con una interpretacin contempornea de la

Orangerie, una tradicional edicacin anexa asociada con las

grandes casas de campo. Se pens que uera una adicin co-herente con el contexto histrico de la casa original, que al

mismo tiempo destacase como un edicio muy moderno.

Se estableci un dilogo entre lo antiguo y lo moderno. La

casa original se dene principalmente por el yeso blancocon el vidrio como material adicional, mientras que la nueva

Orangerie est prcticamente construida de vidrio con ele-

mentos internos secundarios ejecutados como cajas blancas

de yeso. Toda la cubierta de la Orangerie est revestida decobre, al igual que los salientes curvados originales de la

casa. Para las puertas principales de la elevacin este, se

utilizaron pantallas peroradas de cobre prepatinado, dndo-

le a la Orangerie un aire de transparencia.

Cobre Transparente

Con la transparencia de las achadas de cobreperorado y de vidrio y con su separacin sica,la Orangerie se distingue de la casa principal y elpaisaje circundante fuye a travs de su espa-cio. Para diuminar an ms la transicin desdeel interior al exterior, el suelo interior de piedra seextiende hacia uera siguiendo el contorno de laproyeccin de la cubierta. Una supercie de ma-dera se extiende en torno a este suelo de piedra,contando con una mayor anchura en el lado surpara ormar una bonita terraza.

La uncin principal de la Orangerie en su plan-ta baja es la de recepcin y bienvenida (Meet &Greet), en gran parte dentro de la zona de come-dor. En esta planta tambin se encuentran una salade conerencias y un auditorio separado en unazona interior y otra exterior. La primera planta dis-pone de dos ocinas abiertas, as como pequeosdespachos, mientras que los espacios secundariosestn contenidos dentro de las cajas blancas. Porencima de estas cajas, en el lado norte, la cubiertade cobre se levanta como un sombrero para alber-gar la salida de aire.

UNA FUSINDE LO MODERNO

Y LO ANTIGUOEste proyecto muestra la creacin de una nueva vida paraedifcios antiguos, con instalaciones que satisacen lasnecesidades del siglo XXI y sin dejar de respetar y cele-brar su integridad. Una nueva ampliacin con un reves-timiento de bronce supone una declaracin dramtica yuna intervencin delicada - el conjunto es una armoniosausin de lo moderno y lo antiguo.

Situado en el rea de Conservacin Riverside Abbey Road de Ro-

ding Valley en el este de Londres, el edicio del granero, protegidopor su inters local, haba estado desocupado y abandonado du-

rante bastante tiempo y necesitaba urgentemente una restaura-

cin completa para volver a usarse de nuevo. En 2009 se le conce-

di la licencia de obras a un diseo realizado por Schmidt Hammer

Lassen (SHL) para un nuevo barrio de industrias creativas cen-

trado en los antiguos edicios del granero y la brica de cerveza.

Un Toque Ligero

Se eligi al estudio de arquitectura Pollard Thomas Edwards ar-

chitects (PTEa), para desarrollar el diseo de SHL - en esencia se

buscaba optimizar el uso del espacio tanto en los edicios nuevos

como en los antiguos y, al mismo tiempo, preservar el carcteroriginal y las reerencias histricas. Aunque para reparar y res-

taurar la estructura original se necesit una obra importante, en

la medida de lo posible el espritu de la conversin ue la restaura-

cin sensible - un toque ligero. El granero restaurado con su nueva

ampliacin revestida en bronce, ser la nueva sede de la empresa

Roo y contar tambin con otros usuarios creativos y comercia-

les. Roo ha introducido mtodos de construccin sostenible para

proporcionar un entorno de trabajo de alta calidad a un coste via-

ble.

La nueva ampliacin es respetuosa con el edicio original y se ins-

pira en la orma de su cubierta a dos aguas. Los nuevos materiales,

sobre todo los paneles de bronce, complementan an ms el origi-nal. La entrada se abre directamente a un ncleo central de circu-

lacin vertical entre las dos alas, que ha sido cuidadosamente in-

tegrado en la estructura del antiguo edicio - con unos materiales

modernos, un color y una iluminacin que complementan el origen

histrico del mismo. Este ncleo le da un corazn nuevo y dinmico

a la edicacin, totalmente accesible al pblico. El nuevo edicio se

une al ya existente a travs del ncleo de circulacin vertical y de

un puente que sirve de enlace en un nivel superior.

ENTREVISTA

Chris Hodson dialoga sobre el diseo del reves-

timiento de bronce en este proyecto con Andrew

Stokes, arquitecto del proyecto del estudio Po-

llard Tomas Edwards architects.

CH: Cmo se desarroll el diseo de la am-pliacin?AS: En un principio, trabajando con SHL,utilizamos tcnicas tales como el estudio delas relaciones volumtricas, para explorar laorma, el diseo de aperturas o la insolacin.

CH: Qu os llev a la eleccin del revesti-miento de bronce para la nueva ampliacin?AS:La propuesta inicial de SHL utilizaba ace-ro Corten, pero se sustituy por cobre debido alas preocupaciones del cliente sobre la erosiny la impermeabilizacin. Posteriormente, seconsideraron el cobre, el bronce y el latn jun-to con otros materiales metlicos, pero al nalelegimos el bronce. La intencin era darle a laampliacin una esttica moderna que contras-tara de orma dinmica con el contexto hist-rico, mientras que al mismo tiempo reconoceesta historia mediante el uso de un materialde construccin tradicional como el bronce oel cobre.

CH: ambin considerasteis los cambios en elmaterial con el paso del tiempo?AS: La resistencia a las condiciones climticastambin ue undamental, dado que la cubier-ta es muy visible y evolucionar con el tiempode manera dierente a las supercies vertica-les. Nos inormaron que, en el corto y medioplazo, el bronce seguramente evolucionara un

poco ms uniormemente.

CH: Y la sostenibilidad y los aspectosmedioambientales? Fueron importantes?AS: S, denitivamente. Al igual que el cobre,el bronce tiene unas credenciales sosteniblesslidas y probadas en materia de durabilidad yvida til, no necesita prcticamente manteni-miento y puede ser totalmente reciclado.

CH: Cmo se consigui el excelente diseode las achadas?AS: Utilizamos maquetas de trabajo para ex-

plorar dierentes ormas de expresin del re-vestimiento metlico, por ejemplo, la orma yel tamao de los paneles y la direccin de lasjuntas: verticales, horizontales o inclinadas. Laorma del edicio requera de un enoque mstridimensional, ya que la cubierta es esencial-mente una pared inclinada, y estas maquetasnos han permitido comprender la interaccinde elementos clave como ventanas y clarabo-

La regeneracin de la zona que se encuentra por encima del centro comercial situado en el cora-

zn de la ciudad de Helsinki, proporciona una solucin sostenible para un muy necesario espacio

de ofcinas. El uso extensivo de un revestimiento de cobre prepatinado en esta nueva interven-cin complementa el tradicional ondo de cobre verde que caracteriza al perfl de la ciudad.

La torre de ocinas del Evli Bank es un

edicio de nueva construccin en un lugar

inusual est construido en la parte su-

perior de un enorme centro comercial en

el corazn de la ciudad de Helsinki, que

alberga ocinas y comercios. Evli Bank

ya operaba desde varios sitios del centro

comercial, pero quera tener a todo su

personal bajo el mismo techo. Es casi im-

posible encontrar terrenos vacos para la

construccin en el centro de Helsinki y la

ubicacin de una nueva ocina en la parte

superior del centro comercial supona una

buena solucin.

El nuevo edicio de cinco plantas utili-

za el espacio desaprovechado en la parte

superior, incluyendo las antiguas zonas

de aparcamiento. El edicio de estilo co-

mercial se encuentra dentro de una zona

pavimentada, parcialmente rodeada por

las partes ms altas del centro comercial.

Su revestimiento de cobre y su orma de L

denen una nueva caja totalmente acrista-

lada que inunda de luz el interior. Este es-

pacio se adentra a continuacin en el edi-

cio original, introduciendo la luz del da

y proporcionando una circulacin vertical.

Un material determinado por el contexto

Segn Olli Rouhiainen del estudio de ar-

quitectura CJN, las dos consideraciones

ms importantes en la eleccin del cobre

para las achadas ueron el importante

contexto histrico y cultural del centro de

la ciudad, y la presencia de muchos edi-

cios cercanos revestidos de cobre. Su ubi-

cacin elevada demandaba un material de

prestigio y los edicios originales del cen-

tro comercial ya tenan achadas de cobre.

Las achadas del Evli Bank utilizan co-

bre prepatinado con un diseo que reve-

la un poco de las tonalidades tpicas del

cobre oxidado, oreciendo una supercie

variada y vibrante. Este material se utiliza

de dos ormas: en perles curvados como

una supercie continua y modulada, y en

un sistema horizontal de listones crean-

do transparencia. Las secciones de listo-

nes de 90mm estn jadas a los perles

de montaje, que tienen una supercie de

color cobre oxidado, utilizando remaches

a prueba de cido. La combinacin de

estas dos achadas, mejoradas con las

supercies de cobre prepatinado, aporta

una nueva capa verde al per l histrico de

Helsinki.

A timeless skin o pre-oxidised copper is used to express thenew additions, starting as a rusticated base to the originalclassical villa. Te horizontally stratied dark copper thendevelops into a new spa building which denes and dividesseparate external areas either side. Te overall compositionaims to create a place with clearly recognizable connotations respecting the existing architectonic and landscape values.

As architect Steania Masera explained: Te demands o abuilding complex accommodating various dierent unctions

but still presenting itsel as unitary whole suggested the creation

o new circulation routes on two levels leading into a new ad-

dition. Tis addition then defnes a new, open, main entrance

courtyard to the complex. It also establishes, in conjunction

with existing buildings now converted to bedrooms and suites,

a more intimate courtyard characterised by a central, light

timber pergola structure. Te copper additions draw together

the diversity o buildings and their spatial organisation, creat-

ing a place with clearly recognizable connotations.

TimelessCOPPERIn its inspirational rural setting at the oot o Italys Mon-

errato Hills, Rocca Civalieri was the summer sanctuary

o Piedmontese nobles rom the late Middle Ages. The

villa and its associated buildings have now been restored,

adapted and drawn together by a thoroughly contempo-

rary, copper-clad intervention which ully respects theoriginal building abric, to create a convention centre, ho-

tel and spa.

Site Plan, showing the 30ha complex, with the new building highlightedred and original 19th century buildings black.

Commissioned in 1876, the Filtry Waterworks was designed by

British engineer William Lindley, who had previously gained rec-

ognition working with railways and, particularly, municipal in-rastructure projects in numerous European cities. He designed

the rst underground sewers in continental Europe and, together

with his sons, he designed systems or cities in Germany and else-

where including St. Petersburg, Budapest, Prague and Moscow

also turning his attention to urban planning.

At Warsaw, he created a water purication system that contin-ued to operate until the latest regeneration work. Here, he also

collaborated with the architect Julian Herde with a complex o

buildings generally aced with red ceramic tiles and decorative

sandstone elements. Roos were metal sheet on structural steel

and windows steel-ramed. A key aspect o Filtrys success in its

urban context is the green landscape covering about 70% o the

site area. This unique and historic inrastructure complex is pro-

tected locally and listed as a UNESCO World Heritage Site.

Upgrading PerformanceThe well-loved landmark endured various changes ater the

19th-century including additions in the 1970s which took no ac-count o the local environment and attached no importance to

the original buildings scale and orm. In the mid-1980s, restora-

tion o the original buildings began under the current architect,

Richard Sobolewski o Dorjon International, including replace-

ment o the zinc-coated iron plate roos with copper. Technical

and perormance requirements have driven the latest, recently

completed new treatment building. Water quality has now been

improved within modern parameters and in line with European

Union standards, and the use o chlorine dioxide or water disin-

ection and treatment has also been substantially reduced.

The regeneration of a remarkale 19th-century water treatment

complex serving Warsaw takes a traditional approach with

steeply-pitched copper roofs aove rick walls, referencing

without copying the style of the original architecture.

Original 19th century buildings (shown black on the Site Plan) have already been restored with copper r oos.

8/2/2019 caf32_spa

The architects aced major challenges in accommodating the

complex technical demands o the plant upgrade. From an ar-

chitectural perspective, they have taken the original buildings as

their reerence point. They have rejected the notion o introducing

modern orms and interventions as a contrast to the remaining

abric. Instead, they have embraced the architectural language o

massive 19th century inrastructure buildings. Richard Sobolews-

ki commented: We have not replicated the original architecture

but have developed a similar character or the new block using

modern materials. Extensive copper roofng plays a central role

here and gives the permanence that buildings o this type merit.

Key to the architects approach is the dierentiation o architec-

tural orms or individual building elements. For example, steeply

pitched roos with strongly expressed gables covering particular

areas contrast with landscaped green roos over the main lter

hall. Dramatic interiors result rom the large spaces generated by

this type o inrastructure building, and brick and ceramic clad-

ding dominate internally. Natural daylighting plays an important

role where appropriate, via generous provision o roofights and

substantial vertical glazing.

Bringing Life to SurfacesThe problem o large windowless aades, dictated by buildings

o this type, has been successully resolved by planted embank-

ments, creating a park-like landscape, as well as contrasting

material textures and colours. The interplay o suraces is also

emphasised by the way the roos are aceted and shaped. Dier-

ent orms o pre-oxidised copper sheet have been used, includingstanding-seams alternating with the wider batten-role joints to

generate a rhythm across the long-strip installation.

It is particularly appropriate that such a large amount o copper

roo surace is used on a complex dedicated to the delivery o

Architects team31 explain the rationale behind contemporaryinterventions to a traditional Luxembourg village house.

Copper Cottage

8/2/2019 caf32_spa

27/40


The owners o this 19th century cottage in a small village north o Luxem-bourg decided that they would retire there. The house, as it was, had thecharm o an old cottage but did not oer the required comort or a mainresidence. The attached barn was being used as a garage and shed and the idea

was to transorm this huge empty volume into a new living room with a kitchen -

and to alter the existing cottage as little as possible.

Various considerations infuenced our design. The existing cottage has ver y small

windows which give uninteresting views o neighbouring buildings, roos and

streets. The owners wanted views o their own property, gardens and the land-

scape. The existing stairs in the cottage were narrow, too steep and considered

to be dangerous. It was decided that they should be replaced with wider and less

steep staircases or saety and comort.

As the cottage will now be used by older people wishing to spend

the rest o their lives there, it seemed obvious to design the layout in

preparation or potential uture mobility issues. As a result, it was

necessary to locate a kitchen, living room, oce, sanitary acilities

and sleeping rooms all on the ground foor o the building, whilst

retaining the possibility o a second, independent living space in

the cottage. From an architectural point o view, we considered it

necessary to clearly dene the new parts o the building and the

existing 19th century building. The owners wished to retain the au-thenticity o the existing cottage, which was probably built between

1805 and 1820.

Designers Response

Working with the interior designer, our analysis o the owners pro-

posal rapidly revealed that the barn was not big enough to accom-

modate the new living room and kitchen. Moreover, there were not

enough windows on the acade to allow sucient light into the living

room and they did not oer the desired views o the landscape and

the property. It was thereore obvious that an extension was neces-

sary. In accordance with the wishes o the owners, the orms o the

new volumes signal a contrast between our way o living now andthe way we lived some 200 years ago.

As a result, the old and the new are interrelated - yet provide a

contrasting eect. The transition rom old to new does not operate

on one precise borderline but rather by the eects o transparency

and sightlines rom old to new and vice versa. The new, very large

plate glass windows open the perspectives up to the more set back

location o the cottage. The old cottage has been kept in its original

state (almost), with its conguration o small rooms, low ceilings

and exposed beams and old stone and parquet foors.

The acades and roos o the new volumes are characterisedby a covering o copper used here as a modern material. It is both

rustic and modern, and with a visual appearance that develops in

sympathy with the rural setting in the north o the country.

An undistinguished 1970s ofce building in the Netherlandshas been transormed with a rootop extension encased by

a transparent copper skin enveloping the original building.

The building owners, Trinit Automation Uithoorn (NL), sought to

express the companys innovative nature in the expansion o their

oce building. As well as upgrading with higher energy peror-

mance and other improvements, the project also needed to create

more space. This was achieved with a rootop extension providing

a canteen and meeting rooms, as well as a large multi-purpose

seminar room. Here, high, sloping ceilings give a distinctive char-

acter to the internal space.Integrating Intervention

Externally, the intervention is conceived as a three dimensional

box-like orm, rmly integrated into the existing building abric

and reacting with existing acades not just a new storey sat on

top. The new box is completely covered in a transparent copper

mesh skin, simply passing over windows, rames and solid walls

behind, providing a seamless continuum expressing the geomet-

ric shape o the addition.

The designers, Architektenburo Ten Hove, commented:

We deliberately chose copper for the mesh skin, where the colour

of the material naturally changes over time and therefore indicates

the age of the building.Using a grid o equilateral triangles gives

reedom rom the constraints o linear structures and, with the

copper mesh, diuses the box suraces externally. But internally,

the mesh screen still allows clear views to the outside while pro-

viding solar shading, and inward opening windows allow ventilation

and cleaning.

Copper or house on the rock

St Georges Church in the unell ParkConservation Area was built in 1867 as ahistorical, circular building based on a 5thCentury Greek Church and modelled onShakespeares Globe Teatre. Te build-ing has had a colourul past. Saved romdemolition in 1973, actor George Murcellturned the church into the St GeorgesTeatre. More recently it ell into thehands o squatters and it was only whenthey were nally evicted in 2006 that theproject was able to commence.

As well as its primary unction as a church,the building is also used as a community

centre, adult learning centre, crche anda venue or other social events. o meetthese demands, a new, copper-clad exten-sion creates a contemporary architecturalsolution contrasting with the churchaesthetic, yet remaining subservient to theoriginal building and making no attemptto emulate its style. Tis modern 2-sto-rey extension links the existing churchand the bell tower and provides exiblemulti-purpose spaces to meet the needso both church and community. Te newintervention is separated rom the originalabric o the church by a continuous bando glazing.

Matching the contemporary materialityo the new building with the stone andslate o the existing church provided awelcome opportunity to explore solutionsor an ever-occurring challenge. Copper,with timber cladding and glass, providedthe answer with a naturally changing sur-ace and an air o permanence. Te de-signers endeavoured to minimise energydemand by considering the embodied en-ergy o materials and using recycled mate-rials wherever possible.

Regeneration o this 19th century London church involved an extensive reurbishment programme to return the building

to its ormer use. But it also involved a modern extension to provide a permanent home or the growing, 3,000 or so,

congregation o the Nigerian-based House on the Rock church, as architects Paul Davis + Partners describe.

Since 1999 we have been working on a

lengthy process o study, research, con-

solidation and retrieval o the remains

o Ribadavia Castle. The remains are ex-

tremely ragile due to their abandonment

and the neglect o local government in thepast. Ribadavia Castle is located within the

historic area o the village and was built in-corporating the old wall and supported by

a series o circular and square towers on

a large rock outcrop. There is no record o

the earliest human settlement, apart rom

the act that a necropolis and a temple ex-

isted in the upper part o the town, where

the castle now stands.

Castle entrance approached via the straight staircase bridge with cur ved brass handrail.

establshng a Mthodology

We believe that maintaining, transorming

or reusing this historic building requires at

least that we understand its physical and

emotional realities, in its present state

and throughout its history. Through very

careul observation and systematic docu-

mentation, intensive research o histori-cal sources, technical analysis, study o

pathologies, identication o traces and

memories, and nally a refective intuition,

we have established a methodology ex-

pressed in a Master Plan or this castle

that will substantiate the basis or uture

interventions in the monument, thus creat-

ing the potential or its transormation and

reuse.

Strngth and Mallablty

A part o the intervention was to design

the entrances to the ruins o the Castle.

It was decided to make various individual

elements in brass, and also bronze, to give

a jewel-like quality amongst the ancient

building abric. These included access

bridges with stairs, gateway doors andexhibition display elements. The choice

o brass was based on its qualities as a

material that ages with time, developing a

patina just as the stone walls have done.

Its strength and malleability was essen-

tial in the creation o these disparate ele-

ments.

A gradual regeneration is taking place to the ancient Ribadavia Castle in the Ou-rense area o north-west Spain, heralded by new brass elements transorming the

entrances to the castle. Architect Miguel Angel Calvo Salve describes his approach

to these interventions, which add an ageless simplicity and sense o permanence.

The original, early 20th century building

had been unused or over 40 years and

its previously hidden, undistinguishedrear aade was exposed by the creation

o a new public square in the 1980s. The

restoration and expansion o the building

provided an opportunity to redene a new

urban role. The European unded project is

or a new Centre or Cultural Activ ities or

Youth and is unique in Italy. It provides a

link between the University and the World

o Employment, creating an international

ocus to serve the local community.

A Bold Approach

The regeneration carried out in conjunc-tion with engineers Arup (structure and

energy strategies) and Manens (installa-

tion) refects a bold architectural and

urban planning approach. It involves res-

toration o the original building and addi-

tion o a new volume, in the orm o shell

made o steel, copper and glass.

The prole o the shell develops a close

relationship with its urban context. It is

closed next to the old buildings, orm-

ing an intimate interior space, then open-ing up with a large glazed ront drawing in

the new square. The main aade onto the

square is completely glazed, with microp-

erorated brise soleil that protect the in-

terior rom direct sunlight, and character-

ised by dierent heights. A second opening

smaller and varying in shape, is on the

north side, opposite the old buildings.

Architect Luisa Fontana explains how a shell-like copper and

glass intervention regenerates a disused public bath house

and reorientates the building to defne a new urban square.

Energy IndependentThe building is also an example o smart de-

sign and energy sel-suciency, to minimise

energy consumption and carbon emissions.

Dynamic thermal modelling sotware, de-

veloped or the Arup building energy simu-

lation, enabled solutions to be optimized

and energy saving benets quantied. The

project has achieved an A certication inthe Eco Domus energy class with a system

developed by VI. Energy.

The result is an integrated organism, en-

ergy independent rom the network, where

climate and environment interact. Various

renewable techniques are incorporated in-

cluding geothermal energy, the pre-heating

o primary air through an underground maze

and sel-generation o electricity using bio-

diesel. The design optimizes natural lighting

and ventilation, while the building materials

provide a high perormance, thermal inertiaenvelope.
