Perquè BCN

Una explicació del significat didàctic del treball dels estudiants de la Universitat Zürcher Hochschule für Angewandte Wissenschaften (ZHAW) de Zürich, realitzat a l’àmbit del Carrer Pere IV de Barcelona. Des de fa alguns anys existeix un conveni d‘intercanvi mitjançant el Programa Erasmus entre la UPC-ETSAB i la Universitat Zürcher Hochschule für Angewandte Wissenschaften (ZHAW). Alguns estudiants dels darrers cursos de la carrera tenen la oportunitat de participar en aquest conveni. El projecte realitzat al llarg del de semestre de primavera de 2009 de la ZHAW a Barcelona, dóna la possibilitat de presentar en aquest lloc, l’escola d’ Arquitectura de Barcelona - l’ETSAB -, la petita Escola d’arquitectura de Suïssa i el seu mètode de treball. Amb la introducció dels nous programes de ‘Bachelor i Màster`, dins l’acord marc de l’any 2005` , es van ajustar i es van adequar els programes existents d’estudi a mida dels nous objectius, que es van acordar amb els docents. “Habitar” és el tema central de la formació del segon any d‘estudis del Programa ‘Bachelor` d‘Arquitectura a la Universitat Zürcher Hochschule für Angewandte Wissenschaften (ZHAW). En el tercer semestre, el mòdul “Projectar i Construir” tracta el tema de l‘habitatge particular i es treballen els diversos aspectes de l’habitatge a les ciutats petites i als pobles. En el quart semestre, el projecte es centra en un context més urbà. No obstant això, l’exploració dels estudiants no treballa la idea clàssica de l’habitatge en massa,

sinó que explora el tema “Habitar” en projectes de menor abast, més específics. Després de similars feines de recerca a Berlín i a Londres en anys anteriors, aquesta vegada el nostre camí va arribar a Barcelona. Aquest exercici volia centrar-se en les particularitats del lloc, les formes d’habitar i les tipologies d’habitatge, pròpies de la ciutat, les quals no semblaven fins ara exportables ni factibles a un context urbà i cultural com el de Suïssa. L’objectiu és ampliar la nostra mirada amb projectes en el context europeu, a fi de preparar-nos millor per assumir i adaptar-les a les singularitats de l’àmbit suís. Perquè amb freqüència l’accés ordinari a la informació dels projectes queda ocult i no permet trobar solucions innovadores per contexts urbans mes complexes. Per abordar les qüestions de desenvolupament urbà, espai públic i habitatge, els docents van escollir Barcelona, per ser aquesta una ciutat amb una planificació urbana important; pel seu destacat procés d’ampliació d’escala i per la seva significativa remodelació. L‘àmbit d‘estudi es troba al voltant del Carrer Pere IV, un lloc central del Pla Cerdà. Aquesta àrea presenta una gran proporció

de béns industrials en transformació (deterioats?) per això s’inclou en els programes actuals de desenvolupament de la ciutat, com el 22@BCN. En contrast amb les remodelacions de gran escala que es proposen des del 22@BCN, els docents i estudiants de la ZHAW, com altres col·lectius i professionals de Barcelona han suggerit des de l’inici de la transformació, persegueixen una continuïtat amb els teixits existents a traves del treball a petita escala. En cap cas els treballs dels estudiants poden ser propostes per al desenvolupament d’algunes parts de la ciutat de Barcelona. Senzillament el nostre treball no pretén ser d’urbanisme. No obstant això, els projectes ofereixen una mirada fresca i despreocupada i podrien ser motiu per a obrir un debat. Si els projectes dels estudiants demostren que el desenvolupament “pas a pas” en aquest important àmbit podria arribar a ser útil, això seria un bon efecte secundari d’aquesta exposició.

Why BCN

The didactic significance of projects carried out along the Carrer de Pere IV in Barcelona by students of Zurich University of Applied Sciences

For the past few years Zurich University of Applied Sciences (ZHAW) has had an exchange agreement with UPC-ETSAB under the Erasmus Programme. A handful of students regularly take advantage of this agreement, shortly before they leave the institutions. A semester project carried out by the ZHAW in Barcelona during the spring semester of 2009 has provided us with an opportunity to present our small Swiss architecture school and its approach and methods. The Bachelor’s and Master’s degree programmes that were introduced in 2005 have allowed us to refine the existing courses of studies and, with input from the teaching staff, focus them more precisely. The focal point of the second year of the Bachelor’s degree course in architecture at Zurich University of Applied Sciences is “Living”. During the third semester, students taking the “Design and Construction” module consider various aspects of living in single-family homes in the context of small towns or villages in Switzerland. In the fourth semester, the focus moves to an urban context. The students’ project work continues to revolve around the theme of “Living”, and does not shift to the study of classic, large-scale residential architecture.

Over the years, projects have taken us to Berlin and London; this time, we came to Barcelona. We want our students to develop an eye for local idiosyncrasies and characteristics, as well as for typical housing forms and typologies that had not hitherto appeared possible or desirable in a Swiss cultural context. By taking our students on an indirect route and involving them in projects in the context of a European city we aim to prepare them better for the particular idiosyncrasies and characteristics of a Swiss residential area. The apparently normal can, all too often, cloud the approach to innovative solutions. In order to be able to concentrate in depth on issues of urban development, public spaces and city living, the teaching staff chose Barcelona as a place marked by notable urban planning measures, large-scale enlargement of the city and striking urban transformation projects. The students were told to consider the central area around the Carrer de Pere IV within the Cerda Plan. Its large number of old industrial buildings have given the area a certain air of decay, making it the focus of urban development programmes such as the 22@BCN. In contrast to the radical, largescale reshaping being planned for the district, the lecturers and students of the ZHAW chose to

take a small-scale approach, in keeping with the existing structure of the district. Local architects and urbanists have done this before. The students’ projects should not be considered under any circum-stances to be serious urban planning proposals for the development of parts of Barcelona. Urban planning is not that easy or that simple. These fresh and carefree projects could, however, prompt discussion. Should these student projects show that development in small increments can point in the right direction, then that would be a successful side effect of this exhibition.

Introduction The topic for the semester assignment was “Living in the Context of the City”. As we wanted the students to immerse themselves in issues of urban development, public spaces and urban living, we chose Barcelona as a city characterised by important urban planning developments, metropolitan expansion on a large scale and audacious transformations. Our work focused on the centrally-located industrial district on the Carre de Pere IV, in the eastern part of Cerda’s extension of Barcelona. This area is undergoing a process of change. Under the terms of our concept, the district was to keep its own specific character although its buildings were being gradually renewed as it was refashioned into a mixed-use city district.

The 22@BCN urban development programme is proposing a radical rework of the area; in contrast, we chose the path of converting and continuing its existing detailed structure. We felt that the area along Carre de Pere IV was perfect for working on individual buildings in an urban context. For one thing, the Cerda Plan divides the district up into distinct, manageable units and, furthermore, the concentration and heterogeneity that are typical of the district provided motivation for the students’ projects. We started by carrying out a brief urban planning analysis of the area. Then each block was examined by a group of four students, who formulated concepts and strategies for renovating the blocks and increasing their density. The students went on to draw up master plans on the basis of their concepts and strategies. Each student used the

perimeter

master plan as a basis for his or her own individual project proposals. The emphasis was on living, as set out in our curriculum. In developing their strategies, we wanted the students to recognise the existing structure of the block, so that they would be able to use it intelligently for their own projects. The students did not limit their interventions to the edges of the blocks: instead, they aimed to open up the inner depths of the “manzana” with their residential buildings. Where existing buildings prevented any concentration, single structures – mostly empty factory buildings – were torn down or included in the new project as public, roofed, exterior spaces. What resulted were new structures consisting of existing and new, usually four- to six-storey, residential buildings that formulated a rich fabric of inner alleyways, open spaces and courtyards.

The coordination of the projects was mainly concentrated within the “manzana”, as many of the residential buildings occupied the interior of the block and the outer edges of each block were defined by the Cerda Plan. The various teams had to work together to define the street and square spaces outside the blocks. The students also worked together to agree where the high rises should be placed: almost all of them were located on the Carre de Pere IV in order to trace the axis of this road, with its Roman origins, as it runs diagonally across the right-angled grid. As we worked on the renewal and rebuilding of the area along the Carre de Pere IV were able to benefit from a rich stock of existing structures, forms and materials, which provided a great deal of inspiration for the projects on display here. However, as we wanted to ward off any danger

of limiting ourselves to what we encountered, and because we wanted to open up the design process, we looked for an additional source of stimulation. We found one that ultimately proved to be the driving force behind the development of the projects. Knowing that Spain’s tradition of building contains Moorish elements gave us the impetus to pay closer attention to the tradition of the Arabic courtyard house. We discovered a great wealth of spatial differentiation between the public and the private – the principle of gradual equilibrium between opposite poles.

Stefan Hartmann The new building is part of a series of high-rises lining the Carrer de Pere IV and expresses the vertical concentration that we are aiming for in the district. Both the building’s alignment and the firewalls that are typical found in Barcelona provided the inspiration for varying styles of façade. The four types of apartment in the residential high-rise are grouped together on three storeys. The apartments are interlinked with one another in such a way that each is oriented on three sides. The central stairwell receives natural light from the side through adjacent loggias. These also provide access to the various apartments.

Lukas Somm The building follows the line drawn through the urban grid by the Carrer de Pere IV, accentuating the nature of the district’s urban design and adding a touch of new life to the Poble Nou area. The design addresses the issue of blurring boundaries between indoors and outdoors, between public, semiprivate and private spaces. The resulting zones offer residents countless ways to adapt the available space to their personal requirements.

Michael von Allmen The new building combines the corner of a block with side structures. A meandering shape was chosen in order to develop a unified architectural language. The long building, with its quatroplex apartments, aims to be both a single-party and a multi-party residence – a kind of hermaphrodite. The corner structure fans out, its stacked duplex and single-storey apartments presenting an urban face. The mono-concrete construction is consistent with the building’s stylistic vocabulary, which is dynamic in both layout and floor plan.

Roman Pfister The new building complex formulates the open corner of the city block, forming a courtyard that is, in turn, part of a central linking element. Access to the two wings of the building is gained through central courtyards. A stairway with overhead lighting from the very top leads to the apartments. These are laid out around a central, two-storey space that borders a roofed outer area.

Dominik Arni Our design team was faced with the question of how to deal with the differences in scale within the “Manzana� in an urban planning context. What emerged after some intense discussion was a high-rise that is taller than the surrounding buildings, but that nonetheless fits in with the other small plots of land in the area, thanks to its own small footprint. Six different types of apartment were designed; their oneand-a-half storey living or dining rooms mean they are interlinked. Care was taken in the layout to ensure that one could walk through the larger flats in a circuit. Brise soleil-like elements give the building a distinctive appearance and form extended living areas, either as loggias, when used as outdoor space, or as niches indoors.

Baseli Candrian The building stretches back from the street to a small roadway within the city block, undergoing several changes as it does so. Its depth, its height and its relationship to neighbouring buildings all change; the most important common element is the open space in front. The idea was to create flats adapted to the situation, with generous outdoor spaces. These spaces are arranged at the periphery and can be treated at will as extensions of the indoor area. The ground floor can be entered from grassedover open space, while access to the apartments is from the street behind. A central apartment straddles both parts of the building. The outer spaces are generally bordered by the living room, dining area and kitchen.

Mathias Gassmann The project deals with the existing structures on the site, as well as with the concept of living in an open-plan space between two external areas. The district’s special character is further emphasised by this unusual concept for living. The project replaces an existing warehouse and uses its surface area. The dining and living area of each apartment is a generously proportioned, two-storey space that runs through the elongated building, linking the two adjacent outside spaces with one another. An area of smaller spaces lies next to the main room, terminating in an inner façade. These two spatial structures are not intended to compete with one another in any way: they form a whole, and this is validated by the choice of materials.

This residential high-rise building faces a street and stands at the end of an industrial building, in the middle of a city block. The geometry of both the industrial structure and the high-rise refers to the diagonal course of Carrer Pere IV as it cuts through the street grid. Our master plan calls for either changing the use of the existing industrial buildings or replacing them with residential structures. The industrial building associated with the highrise is to be used as a theatre; the necessary theatrical infrastructure, with its large quantities of equipment, will be housed in the lower storeys of the high-rise. The apartments above alternate between one and two-storeys and offer views over the surrounding buildings on three sides. The rhythmic structure of the building is defined in the faรงade.

The project was greatly influenced by one of the most important design parameters: its position inside the Cerda block. Together with its neighbouring buildings, this project creates public and semi-public courtyards that invite one to linger. The master plan’s system of courtyards and pathways continues in the building’s interior, becoming more refined. Each flat is oriented towards its own private inner courtyards that form a kind of second, open air, living room and create a strong connection between interior and exterior space.

Superimposing the urban structure of the Plan Cerda over the rural structure of the post-industrial Poble Nou creates a complex texture of outdoor spaces. Against this background, the project has developed a differentiated sequence of spaces, offering residents intricate habitats in which to live and work. Squares, courtyards, rooftop walkways, private outdoor spaces and rooms form a continuous texture within an urban area that already exists in part. With its covered market acting as an interface between the district and the rest of the city, our Catifa de Poblenou is set to become one of Barcelona’s local centres.

The distinctive structure acts as a liaison between the corner structure of the block and the heterogeneity of the existing row of residential buildings.

Silvio Albin Our master plan proposes to strengthen the southern front of the block in order to create a spatial conclusion for the planned park on that side. The park is connected to the inner courtyard of the building and Carrer Pepe IV to the north by a new public footpath. The apartments in the building have been designed to relate to both the new park and the courtyard in the middle of the block. Loggias that penetrate deep into the building create attractive exterior spaces. These provide vertical expression, giving the project a marked urban presence and independence.

Jonas von Wartburg From the forecourt through the inner courtyard and on to the back yard: several of the building’s characteristics take account of the advantages of this progression. The layout and floor plans of the apartments indicate their alignment. The shady veranda along the length of the living room is barely more than a plant-filled place in which to read, projecting out into the spacious living room as it winds its way along. Ventilation flaps in the wall overlooking the inner courtyard regulate the room’s indoor climate: both room and air flow.

Matthias Ruf In accordance with the master plan, the project grows out of the middle of the city block, stretching out to the periphery along various courtyards. Most apartments are reached from staircases. Adjacent loggias provide access to the central dining rooms, which are formed by girder systems. Sliding wooden panels separate the rooms grouped around this central space. Duplex and triplex apartments, a shop and a day care centre are located at the front end of the building and have their own, separate, entrances.

Adrian Zwahlen The project is located at the northern edge of Caree 16. It draws its architectural expression from the old industrial buildings next door. A one-and-a-half storey building is included in the project, converted into a parking garage to alleviate the problematic parking situation in the neighbourhood. In keeping with the convention in Barcelona, the ground floor is to be used for businesses and include a cafĂŠ looking onto the courtyard. With a few exceptions, the residential units are designed as flats. Two duplex apartments are planned for the northern side; they will receive sufficient light from a generous, two-storey external space. They will also have direct sunlight from apertures in the roof.

Simon Wiederkehr The residential building stands at a crossroads by the Llacuna metro station; its shape is oriented towards neighbouring three- to four-storey buildings and the seven-storey industrial structure across the road. A tower has thus evolved, rounding off the park opposite. Ten differing kinds of living space resulted from the interaction with the form that was derived, ranging from a studio to a family house that finishes off the tower. A twostorey botanical library and a flower shop are located on the ground floor.

Analysis

Gaps The buildings aligned to the street create an open courtyard in the interior of the block. Some individual gaps in the buildings lining the streets indicate that the district is changing.

Comprehensive building The block has a number of buildings facing on to the street. There are numerous single- and two-storey buildings in the interior that do not allow for courtyards to be used.

Antonio Obrist The building combines the high rise with the town house, shapes the corner of the city block and forms a connection with the existing structures on the three-cornered block that Carre de Pere IV cuts off. The high rise’s slit-like loggias are a reaction to the noise from the surrounding streets, and to Barcelona’s climate. The façade reflects the alternating interior floor plans, which also offer residents an interesting variety of apartments. The roof terrace is open to all residents; it has a pool, fitness room and open fireplace.

Philipp Stäheli The building forms a fitting link between the older buildings to the west and the green glass structure at the corner of the city block to the east. Its ground floor serves to integrate the high rise into existing row of buildings; its height acts as a counterpoint to the bulk of the glass structure. An opening in the façade at ground level enables loggias to turn their backs on the street, as well as providing an attractive entry to the park in the interior of the block. The apartments in the tower are on the small side, but have unbroken views and a transparent metal façade.

Domenic Bßchel The appearance of this city block is marked by large firewalls running at right angles to the street. Reinterpreted, these will also mark the planned new residential block. Rows of narrow, vertical and deep windows will provide shade to the interior and lend the façade weight and volume. The apartments are divided into two areas: one for services and one for living. The living area has a summer and a winter section. The winter section is aligned to the southwest, while the summer area is a large, roofed loggia. This division of summer and winter areas makes the depth of the city block apparent.

Lidia Haag The design deals with the narrow, deep residential buildings that are typical of Barcelona. The design takes over the existing structure of the residential block, with its narrow geometry and faรงades facing the street and an inner courtyard. The apartments link the edge of the block with the courtyard. This link and the depth of the building can be experienced from within the apartments, which open to both sides.

Rückblick Nach den positiven Erfahrungen mit den Masterplänen von London, haben wir uns ein weiteres Mal an umfassende Eingriffe in das Stadtgebiet einer europäischen Grossstadt gewagt – dieses Mal Barçelona. Die Wahl einer mediterranen Stadt am Meer schien uns die passende Folge nach der Vertiefung in die Themen des privaten Aussenraums am Beispiel von Weesen, das obwohl nördlich der Alpen gelegen bereits einige Merkmale eines südlichen Lebensstiles aufwies. Wurden in London mehrere Masterpläne mit unterschiedlichen städtebaulichen Konzeptionen auf jeweils dem gleichen Gebiet entwickelt, strebten wir in Barçelona das ergänzende Zusammenwirken von Einzelbeiträgen an verschiedenen Orten im Gefüge eines Stadtteils an. Ausgewählt wurde das Quartier „Poble Nou“ an zentraler Lage innerhalb des Cerda-Plans. Dieses Gebiet weisst wegen seines hohen Anteils an alten Gewerbeliegenschaften gewisse Verfallserscheinungen auf und ist deshalb in den Fokus aktueller Stadtentwicklungs-programme wie des 22@BCN geraten. Im Gegensatz zu der dort vorgesehen radikalen Neuordnung im grossen Massstab verfolgten wir eher ein „Weiterstricken“ der vorhandenen kleinteiligen Struktur. Der in klaren, überschaubaren Einheiten (manzanas) gegliederte Cerda-Plan eignete sich besonders gut für Bearbeitung von Einzelprojekten im Kontext. Die vorhandene Bebauung war genügend dicht um durch Studentenprojekte ergänzt und wo begründet auch ersetzt zu werden. Je „Manzana“ arbeiteten Gruppen aus jeweils vier Studenten an einer abgestimmten Strategie zur Aufwertung des innerräumlichen Gefüges. Gemäss dem Semesterschwerpunkt stand dabei das Wohnen im Vordergrund und wurde erweitert durch jeweils passende öffentliche Nutzungen im Erdgeschoss.

Bei der Anordnung der Neubauten hat man vermieden sich nur auf den Rand der „manzana“ zu beziehen, also keinen Blockrand zu erstellen, sondern eher versucht die Tiefe zu erschliessen – so wie es das vorgefundene Bebauungsmuster nahelegt. Zur Auflockerung der für Wohnzwecke zu dichten Bebauung wurden einzelne Gebäude – meist alte Fabrikhallen – abgerissen oder als öffentliche, gedeckte Aussenräume in die neue Struktur einbezogen. So entstand ein abwechslungsreiches inneres Gefüge aus Gassen, Plätzen, Höfen und vereinzelt auch privaten Atrien. Insbesondere versuchte man Bebauungsarten zu finden, die ein Weiterbauen im Massstab der für das Quartier typischen niedrigen Fabrikhallen ermöglichen – also eine bewusste Alternative zu den massiven Hochbauvolumen des 22@BCNProgrammes darstellen sollten. Natürlich sahen auch wir Hochbauten vor, die um so mehr in spannungsvollem Kontrast zu den verdichten Flachbebauungen standen. Eigentliche HochhausScheiben setzten wir nur zur Betonung der markanten Axe der Carrer Pere IV ein, die auf Grund ihrer antiken Wurzeln schräg im rechtwinkligen Raster des Cerda-Planes verläuft. Im Allgemeinen fand die Abstimmung der Projekte innerhalb der jeweiligen „manzana“ statt, da viele Bebauungen in das Innere vorzudringen suchten. Anders verhielt es sich bei Eingriffen entlang des Blockrandes. Hier stellte sich die Frage des Verhältnisses zur Bebauung auf der anderen Strassen-oder Platzseite. Waren dort Projekte anderer Studentengruppen vorgesehen, musste eine Zusammenarbeit zwischen den Gruppen stattfinden. In Einzelfällen führte das zur Umkehrung des Entwurfsfokus – nicht mehr die „manzana“ selbst stand im Blickfeld, sondern

die Strassenkreuzung mit der für den Cerda-Plan typischen, platzartigen Ausweitung der Ecken. Neben der städtbaulichen Anordnung war eine der zentralen Fragen die Wahl einer Typologie für die Wohnungen. Nicht von ungefähr bevorzugte man eine Stadt am Mittelmeer in der Nachfolge von Weesen am Walensee. Die Elemente Wasser und mildes Klima in Hinblick auf eine besondere Ausprägung des Wohnens beschäftigte uns seit wir in Weesen entdeckt hatten, dass die Gleichstellung von Aussen-und Innenraum der eigentliche Motor für Neuentdeckungen beim Entwurf von Wohnungen war. Die verstärkte Bearbeitung des privaten Aussenraumes gab sogar die Kriterien für Grundrissform und Übergänge im Wohnbereich. Eigentlich war die Fokussierung auf den Aussenraum eine „fixe Idee“, eine Art atmosphärischer Traum, der die Vorstellungskraft bezüglich der Frage des Wohnens beflügelte und aus dem blossen Umsetzen bekannter Typologie-Vorbilder heraushob. Ein ähnliches Stimulans suchten wir übertragen auf das südliche Klima von Barçelona. Das Wissen um die maurischen Spuren in spanischen Städten wie Sevilla ermutigten uns die Traditionen des arabischen Hofhauses genauer zu betrachten. Wir entdeckten nicht nur das Potential umschlossener Innenhöfe für die Gestaltung privater Aussenräume, sondern den ganzen Reichtum in der Unterscheidung und Öffentlich zu Privat. Diese beiden Pole werden nie direkt einander gegenübergestellt, sondern in feinen Abstufungen wird nach einem Ausgleich des Spannungszustandes gesucht. Für die einzelnen Schritte gibt es einen reichen Fundus an räumlichen Gefässen, wie Schikanen, Vorhöfen, Empfangsräumen etc.


Barcelona

Das Prinzip des stufenweisen Ausgleichs zwischen gegensätzlichen Polen findet sich in der arabischen Stadt auf allen Ebenen. Derselbe Vorgang wiederholt sich in den verschiedenen Massstäben, sei es das Verhältnis von Stadt-Quartier-Platz-Haus, oder von Haus-Hof-Empfangssaal-Privatgemächer. Natürlich ist dieses Regelwerk nicht direkt auf unser Problem in Barçelona anwendbar, doch hilft es als Utopie oder Vision einen Aspekt zu verdichten, der dann sehr wohl hilfreich für die Ideenfindung sein kann. Dieser Vorgang stellt die Frage nach der Rolle der Utopie im Entwurfsprozess ganz allgemein. Angesichts der Fülle des vorhandenen Materials, die bei der Untersuchung einer Stadtstruktur anfällt, besteht die Gefahr sich nur innerhalb der gefundenen Regeln und Typen zu bewegen. Ein neuer Aspekt wird erst gar nicht verfolgt, da er für diesen Fall untypisch erscheint. Im Spannungsfeld zwischen einer Utopie, die zunächst aus völlig fremdem Zusammenhang importiert scheint und

den tatsächlichen Möglichkeiten in der Anwendung entsteht dann wirklich Neues. Tatsächlich haben sich einige Entwürfe in Barçelona einer solchen Utopie bedient und wurden durch die darin enthaltenen Prinzipien und Motive stark aufgeladen. Trotz deutlich weniger heissem Klima liessen sich gewisse orientalische Raumformen und-folgen gut in die europäisch geprägte Wohnkultur Barçelonas einbauen. Vorallem die verfeinerte Betrachtung der Übergänge zwischen Aussen und Innen, und das damit einhergehende vertiefte Verständnis für das Verhältnis zwischen Öffentlich und Privat gaben Kriterien und Leitlinien für die Ausformung der Wohnbauprojekte.
