MANIFESTO Through this project, Modernism is refurbished not only in the literal and architectural terms of the building, but also as an outdated way of living which doesn’t correspond to our contemporary lifestyle anymore. From a ruin, a new working machine is created, which produces and doesn’t only consumes, deeply engaged with the local network and reflecting a future society, characterized by a stronger sense of community and membership affiliation. From a thoroughfare, the Restaurant Walensee is transformed in a destination, becoming more sustainable by completely changing its usage timeframe, reconnecting the users with the land and engaging them in the network of its surroundings. The modernist movement was the perfect reflection of the society for which it was being built for. This building in particular, was the mirror of the post war growing well-being and new freedom of the masses.The new motorway connecting Zurich to the mountains of Graubunden, opened in 1964, was one of the first motorway of Switzerland, representing the need of the population to escape from their daily life and enjoy the economic well-being of that era. It was also a big step for the internationalization of Switzerland which was now accessible and ready to welcome wealthy foreign tourists. Built on an idillic stretch of the highway, on the south shore of the Lake Walen, the Restaurant Walensee was the perfect materialization of the post war dream and the Sachlich ideology, upon which the individual is totally subjected to the masses and architecture was not the expression of the talent of the singular, but rather the necessities of the multitude. It was not designed for one specific user, even though it answered precisely the needs of this latter in terms of functionality. The building was designed to follow the objective needs of the average citizen in that specific context and that specific era. In this sense, like most of the late modernist buildings, this in particular, was built as a machine for the new booming society, a simple place for the masses to enjoy a break during their travelling through the Swiss Alps, framing postcard’s like scenarios on the wonderful landscape. The goal of the Walensee Boat-Building Learning Center is to completely invert these obsolete schemes, to build a more sustainable and connected future: from objectiveness to singularity, from masses to community, from consumerism to producerism, from thoroughfare to destination.
THE PROJECT To reconnect the once Restaurant Walensee to the historical and cultural network of craftsmanship, and people’s behaviour, and to emphasize its connection with the local ressources, I propose to transform this building in a boat-building learning center. With its proximity to the city of Zurich, the Walensee Boat-Building Center, will welcome apprentices from around the country, looking to escape from their digital life and reconnect to the nature rediscovering the traditional wooden boat-building skills of the region, which are slowly being lost. The students will be offered different courses ranging from a couple of days to more weeks, where they will learn this art hands in hands with Mr W., a skilled boat builder. The center accommodates up to 10 students and the owner, and welcomes curious visitors arriving from the lake and traveling on the highway to learn about its activities with its semi-public shared spaces and through the new floating pier, which is the link to the local ferry network and offers a public platform on the lake. Inspired by the organisation schemes used in the naval architecture, the building is refurbished in the same way an old boat would be: only the loading concrete structure is kept, stripped from everything unnecessary and filled with modular and prefabricated wooden cabins, which will ensure the thermal comfort of its users and the best conditions for their activities. The leftover spaces, which are not insulated, host the circulations, deposits and functions with a higher physical activity, such as the building workshop. The ground floor is sheltered with industrial folding doors, and becomes the wooden workshop for the first steps of the boat creation process. From there, the boats travel to the second floor, where they are slowly painted and finished in a second workshop, before crossing the highway through the existing bridge and being launched for a test sail in the lake. The third floor accommodates the cabins of the apprentices and for their tutor. These wooden boxes source from the local forest, rich in spruce timber, the same material which will be used for the construction of the boats. Architecturally, they are modular and composed by 4 different types of sandwich panels, they are completely independent from the existing structure and could eventually be reconfigured for different future needs. On the lake shore, a floating pier is built with the recycled concrete of the internal demolitions of the building. This new extension welcomes the visitors who arrive with the new ferry connection, creates a swimming area and a testing and showcasing area for the boats produced in the workshop.

Interview with Mr Wolf, Bootswerf Wolf, Mols
[We start the interview in his office, which adjacent to the workshop space] Andrea: I’m an architecture student from ETH Zurich and I’m working now on my Master Thesis. I would like to create a new center on the Walensee, to learn to build wooden boats. Mr Wolf: [He gets that I am from Ticino from my German accent, and answers in Italian] We can do this interview in Italian, I am a teacher at the boat building school in Bellinzona, my grammar is not perfect but… W: This is really interesting for me, we are building this year a new boatyard, this is the project [showing me the project, which is reported in the references]. A: Oh really? What kind of boatyard? Only for wooden boats? W: No not only for wooden boats, we will work also with resin boats. There are only two producers in Switzerland who work only with wood, Bösch and Pedrazzini. The production in Switzerland is really low, I’m not sure of the real number, but I think only 300 boats are built completely in Switzerland every year. The boatyards buy the hull from Germany, Italy, but mostly Poland, and then they build the boat around it. A: Why the production in Switzerland is so low? W: The costs are to high, only Bösch and Pedrazzini with their names and fame can afford to produce to these prices, and the market is already really small for them. A: When did you start building wooden boats? And where di you learn it? W: I studied carpentry and then boat building. I opened my business in 1992, I started alone and I have now 8 employees and around 900 clients from around Switzerland: from the Walen lake, from the Zurich lake, the Constanz lake, the Lugano lake,
that’s why the space is really to small here. A: What kind of space do you miss here? More working space or storage or …? W: The space to work is very little and also the space outside is not enough, we are currently renting three houses to store the boats of our clients but it’s a big risk for us, if the owner doesn’t want to rent the space anymore we wouldn’t know what to do. This is why the new project will be divided in two parts, a workshop and a big storage, it’s around 1300 square meters. [We move to the working area, where a couple of wooden boats are being worked on upside down, laying on wooden racks] A: What kind of works do you do here? W: We do everything, from the complete construction of a whole boat, to reparations, to just repainting. Mostly I have to say, we do reparations, only a few clients ask us to build a new boat, it’s very expensive. A: How do you get the clients? W: They call us when they have a problem, we meet at the port, we see the boat and discuss about the works that he wants to do. Then we bring the boat here. If it’s a big boat we use our crane and put it on the trailer, or we can sail until here and then crane it out of the water directly in the boatyard. A: [There is an old taxi boat from the Zurich lake that occupies almost all the space of the workshop] What are you doing on this boat? W: This is a boat that we built from scratch 14 years ago. The client brought us his own material, but it was not ideal for boat building so we are slowly replacing most of the pieces of the hull. He actually sold the boat, and the buyer found out about all the problems that it has and came to us.
A: What kind of wood is it made of? And what wood are you using for the replacements? W: The original boat was built mostly in spruce timber and chestnut from Ticino. We are replacing all the old plywood parts It’s mahogany plywood. A: Where does the mahogany wood come from? Is it Swiss wood? W: No, the sawmill is in Italy, near Milan, but they import it from central Africa. Mahogany is the best wood to build boats, Pedrazzini and Bösch buy their wood from the same supplier in Italy. A: Would it be possible to build a boat with Swiss wood? Or is it necessary to use mahogany? W: Normally to build a boat we use mahogany and mahogany plywood or sapele, which is from the same family of the mahogany, because of its density which is really water resistant. But yes, it would be possible and cheaper to build boats with spruce timber, it only has a shorter lifespan. A: Could we think to use the local wood to build boats? W: Yes of course, the structure of this boat is made of Swiss spruce, and this is chestnut, from Ticino, but it’s really expensive. A: The idea of my project would be to create a wooden boat learning center, where people could go and stay the time necessary, from 1 to 4 or 6 weeks, and learn how to build wooden boats. It would be about small boats, like kayaks and canoes for example. It’s a concept that is popular in the United States, in England and Australia. W: Yes I know this kind of centers. Actually I would also like to offer courses to private customers in the new building, many clients ask us to teach them some skills, but we don’t have the space now. A couple of clients already came to ask for help to build a wooden boat at their home, so I went to their houses and showed them which is the right material, how they should start, which technique
to use to cut the wood, etcetera. I had three or fours clients like this, they wanted to build small boats or even bigger ones, once I client built himself a 10 meters sailing boat, all in wood. A: [Mr Wolf is showing me the renovation of a 50 years old boat] So what kind of wood do you use for this? And will you add epoxy resin on top? W: No absolutely no epoxy! We use the normal spruce timber and mahogany, and we just treat it with some special hydrophobic paints. If you cut the joints with the perfect angles, you don’t need epoxy. Every piece is cut manually with the right dimensions, and then fixed to the skeleton with nails. A: And how do you cut the pieces of wood? Which machine do you use? W: We use normal machines for wood works, like the band saw, the circular saw and the sanders. Then every piece is given the right curve with a manual planer. There is a special manual planer used only by boat builders, the ones we have are 50 or 60 years old and it’s really difficult to find new ones, no one produces them anymore. A: How long does it take to cut each piece? W: Each piece for this boat [the old one] needs around one or two days of work. It’s a really precise work, but building a new boat is faster, because you do all the joints in the same way. To complete the renovation of this boat, we will need at least two months. [We move back from the workshop to his office] W: This is a personal project that I did around 10 years ago [it’s a sailing boat]. I worked together with a naval architect and we drew the boat, and then I built three of them, I sold two and of course I kept the first one for me.
A: And what about the sails? What material is it and where do you get it from? W: In this case I ordered special fabric made of carbon fiber and aramide from Australia. A: I saw upstairs a woman working on a sail, is she preparing a new one? W: No, we don’t make sails normally, now she is repairing the fabric roof of this taxi boat that you saw before in the workshop. We don’t work with sails normally, but there’s someone on the lake of Zurich who does, so if we need some we ask them. W: So, explain me more about your project, where will it be? A: We were given the Restaurant Walensee as a case study, to refurbish and find a new usage, so I’m thinking to create a Boat Building Learning Center. W: I know this building, actually when I was looking for a new space for my firm, I also visited it when was on sale. It would have been a nice place, but it was to small for us. The problem of that place is that the restaurant is to big, and the parking is to small. ●

Architectural expression
destroyed by war, fire, and landslides and then rebuilt, the originally heterogeneous building ascends defiantly and archaically within the landscape, extended by an additional story beneath the new lead-clad roof. Numerous dormers indicate the presence of new guest rooms. The architects maintained the facades and the chapel situated in the northern half of the building and only removed a more recently added story. At the same time, 588 they almost completely renewed the
interior of the old natural stone facade provides sufficient thermal insulation and serves as support for the new wood beam ceilings and roof construction. Interiors are clad with horizontal planks infilled between posts – a traditional construction method in the Canton of Uri. Carpenters prepared wood components in the valley and assembled them on-site in the pass during the brief snowless period. A concrete band set on top of the first floor natural stone wall
portion of the building. On the first floor, visitors are welcomed in the shared areas, accessible via the historic staircase. These areas include a large parlour with an old stove, a reading room, and a coffee kitchen. On the story above, guest rooms are located on both sides of a central corridor. The continuous cladding of walls, ceilings, and floors with unfinished spruce conveys a rustic character and serves as reference to the hospice’s prior use. 2011 ¥ 5 ∂
Altes Hospiz am St. Gotthard-Pass Old hospice, St. Gotthard Pass Architekten: Miller & Maranta, Basel Quintus Miller, Paola Maranta, Jean-Luc von Aarburg Mitarbeiter: Nils Haury (Projektleiter), Mirjam Imgrüth, Sabine Pöschk Tragwerksplaner: Conzett Bronzini Gartmann, Chur Fotos: Ruedi Walti
In der kargen Landschaft des St. GotthardPasses auf über 2000 Metern Höhe finden seit dem 13. Jahrhundert Reisende, Pilger und Händler Unterkunft im Alten Hospiz. Durch Krieg, Brand und Lawine mehrmals zerstört und wieder aufgebaut, erhebt sich der ursprünglich heterogene Baukörper jetzt trutzig und archaisch, um ein Geschoss erweitert, unter dem neuen bleiernen Dach. Zahlreiche Gauben verweisen auf die neuen Hotelzimmer. Die Architekten erhielten die Fassaden und die im Norden angegliederte Kapelle in ihrer ursprünglichen Form und entfernten lediglich eine Aufstockung aus jüngerer Zeit, während sie die innere Struktur des Hospizes fast vollständig erneuerten,
um aufwändige Umbaumaßnahmen der unzeitgemäßen Einbauten zu vermeiden. In den unteren beiden Geschossen sind massive Innenwände und Decken eingefügt. Darüber sorgt eine Holzständerkonstruktion auf der Innenseite der alten Bruchsteinfassade für ausreichende Wärmedämmung und dient als Auflager für die neuen Holzbalkendecken und die Dachkonstruktion. Die Ständer sind mit horizontal gelagerten Bohlen ausgefacht – eine traditionelle Bauweise im Kanton Uri. Die Zimmerer konnten die Holzelemente im Tal abbinden und in der kurzen schneefreien Periode auf dem Pass montieren. Ein auf das Mauerwerk des ersten Obergeschosses aufgesetztes Betonband
11
sichert die Mauerkrone und nimmt die Schubkräfte des neuen Dachstuhls auf. Neue und alte Putzstruktur der Fassade gehen nahtlos ineinander über, neue Kastenfenster des ergänzten Stockwerks zitieren die restaurierten Elemente im unteren Bereich. Im ersten Obergeschoss empfangen den Gast die Gemeinschaftseinrichtungen, die er über die historische Treppe erreicht: eine große Stube mit altem Ofen, ein Lesezimmer und eine Teeküche. Darüber erstrecken sich beidseitig des Flurs die Gästezimmer. Die durchgehende Verkleidung von Wänden, Decken und Böden mit unbehandelter Fichte verleiht ihnen einen urtümlichen Charakter als Referenz an die Vergangenheit.
