At the threshold of the village of Rüti GL stands a quiet industrial building. On its façade, one can just barely make out the words Wollweberei Rüti — a former wool spinning factory that now appears abandoned. Its walls still carry traces of the production, adaptations, and many transformations it has witnessed over more than a century.

The project begins with a territorial ambition: to create a regenerative farm at the scale of the village of Rüti. This vision requires a herd of 300 sheep, not only for landscape management and soil regeneration but also for the production of wool, milk, and cheese. At the same time, the village of Rüti has no access to higher education within 1.5 hours by train, which severely limits opportunities for young people in the region. The idea of combining agricultural production with higher education makes sense — especially in this idyllic setting, where reusing the former wool factory as an agronomy school becomes both a symbolic and practical gesture.

The core architectural idea is to anchor the new program within the existing structure as respectfully as possible. Rather than erasing or drastically altering the old factory, the interventions aim to integrate into it, preserving and celebrating its spatial qualities. The generous industrial volumes are maintained, with minimal additions. Where new elements are introduced, they are clearly readable and reversible. The result is a hybrid space: part learning environment, part productive farm, and part historical artifact.

The energy concept is based on a phased and locally rooted approach. Over several years, the 1850s building is gradually insulated with sheep wool, creating a clear connection between the function of the farm and the materials used in construction.

Underfloor heating is installed in the living and teaching areas, powered by a heat pump connected to the existing Kraftwerk — a former hydropower plant that remains in operation within the building.

Rather than replacing the original windows, they are carefully repaired, and small foam seals are added to reduce air infiltration, preserving their historic character while improving performance.

Architecturally, a major addition is a central circulation core — a staircase that connects all levels and improves accessibility throughout the building.

Moreover, the attic level is reimagined to accommodate guests and visitors. This space becomes a bridge between the local community, the school, and the outside world, supporting temporary stays, workshops, and events.

Finally, the largest architectural intervention addresses the key issue of the complex: the latest storage hall, built in 1982, hides the historic glazed façade from 1916 and casts the main hall into shadow. The intervention is therefore to deconstruct this extension, keep its wooden load-bearing structure, and reuse it to erect a new building with a classic dual-pitched roof. This new volume frees the historic façade and allows natural light to re-enter the main hall. The newly constructed building is dedicated to sheep milking, forming a functional and symbolic link between the herd and the historic fabric of the site.

In short, the project proposes a new rural campus model where farmers, students, researchers, and locals come together. It is a place of production, education, and innovation. It revives the site and responds to the demographic decline that has affected the villages of the Glarus valley since the end of its industrial golden age.

 Since the start of the industrial revolution, the western social system has been built on constant growth. Growth in population, economic performance, technological capabilities, cultural output - no area of human life has been untouched by this dynamic.

But it can no longer be ignored that we are at a breaking point. The planetary boundaries have been reached or already exceeded in many areas. The climate crisis as well as the biodiversity crisis are both negative consequences of this system.

A change of course is therefore not only needed, but inevitable due to demographics. Demographic developments will radically transform the society we know. Even if it still seems to be a distant future in Switzerland at the moment, the population here will also start to shrink in a few decades, even in urban areas. This is already the case in many European countries, and there are also areas in Switzerland that have been shrinking for decades. The area around the Klausen Pass is just such an area.

This project examines two case studies on both sides of the Klausen Pass to find out what kind of architecture makes sense in a shrinking society. How can places be created that enable a sustainable form of growth and coexistence in such a location? On the Glarus side, a new scheme is proposed for the former woollen weaving mill in Rüti, while on the Uri side, an new approach is implemented in the former Gasthof St. Anton in Spiringen.

Such shrinking places have one advantage: the forces of the market are significantly weaker and projects that are not aimed at optimising profits also have a chance to thrive. There is an opportunity to utilise these places creatively through small interventions and make them usable for society.

The projects are characterised by the fact that they consist of a large number of small interventions that can be carried out without great expense over a longer period of time. If an intervention is a success, it can be built upon; if it is a failure, it can be reacted to. In this context, architecture is not understood as a project, but as a process.

By investigating the history of Glarus it became apparent that the textile industry played a significant role. Described as a pioneer work, the heroic and linear narrative still plays an important role in the canton’s identity today. Inspired by Ursula Le Guin’s concept of the carrier bag, a collection of stories was gathered describing that the Glarnerland isn’t only about the heydays of the industry but also about the possibilities it left behind.

One of the stories to be told is explained by Peter Jenny. In an interview, he mentioned that besides the industrial past, the Glarnerland has the quality of serving as a niche and by that attracting artists and other people involved in the cultural scene. After the textile industry came to a halt at the end of the 20th century, space became available that could be exploited. Examples such as the Palais Jaune in Diesbach in the 1980s or the still active Hollenstein in Ennenda illustrate what Jenny was referring to. Both places offered space to communities of people involved in the cultural sector where they could create their own environment, hidden from the rush in the cities.

Also, the Hänggiturm shows a straightforward way of representing the history of the textile past. Reapplying Ursula Le Guin’s method to analyze the building it became clear that the seemingly perfect appearance of the ensemble has more stories
to tell. The old, original factory building was supposed to serve as a base for the relocated Hänggiturm. As the building was a bit too narrow, it was demolished in the 90s and replaced by a new building with the same appearance. One irregularity that illustrates the orchestration is the large basement with an underground garage.

How does this “Niche” manifest itself?
The relocation of the post office that is currently inhabiting the base of the building offers the possibility to introduce a new use. As an extension of the existing cultural network, a residency for artists is implemented into the partly vacated building. Equipped with small appartements it allows the guests to inhabit the building for any length of time. The floor slab to the basement is cut open to unveil the orchestration and to provide the basement with natural light. The space once used as a garage is reframed into a Werkhalle, ready to be appropriated by the inhabitants, starting with a ceramic workshop in which tiles are produced which are installed on the upper floors. Inspired by the structure of the Chelsea Hotel
the ground floor is transformed into the new Lobby of the building. Together with the existing Anna Göldi Museum in the Hänggiturm, the lobby mediates between the public and the newly implemented internal world. The bar, reception, and collective kitchen on one hand welcome the public of Ennenda into the building and on the other hand, serve as an extension of the inhabitants’ living rooms, enabling a community to form around the residence. The seven existing bathrooms on the upper floors allow the plans to be altered into seven smaller apartments. Equipped with a bed and a small kitchen they provide a basis for the individual occupation of the inhabitants.

The aim of the KW Walzmühle project is to restore the existing buil- dings of the Alpenbrückli complex and introduce new infras- tructures in order to re-activate the site and its reach onto the surrounding area and its population. The implementation of a bold communal hall linking the former grain silo and the old mill is meant to generate an intermediate space that could be used by the new users of the complex as well as the daily passers-by from the region. The site is in close proximity to the centre of Glarus as well as the train tracks and stands on a pedestrian path that sees a daily flux of users crossing the old mill factory thus making it a place with a high potential for social & commercial gatherings as well as a distribution node for locally produced goods.

The new site would offer a new commercial hub for the city of Glarus, allowing local producers & suppliers to gather in a centralised environment where each could benefit from the experience and networks of each other. The goal is to introduce a variety of co- working spaces, showrooms as well as storage facilities that could enable national and international investors and distributors to come and meet in person with a broader range of small to me- dium-scale producers in order to facilitate the export of locally produced goods across the rest of the country as well as beyond our borders. The importance of the local economy and locally sourced productions is becoming a critical part of fair trade poli- cies as well as the development of suburban regions that develop products further away from economic centres such as Zurich.

Diverse state entities and private companies have already taken the challenge to boost the economy of smaller companies and expand the reach of new start-ups and producers outwards of the valley in order to bring the region to a more competitive state in opposition to the country‘s leading food distributors like Coop and Migros. These mega companies control the majority of Switzerland‘s food market and thus possess an essential influen- ce on the prices and distribution networks of goods across the country making it very difficult for smaller companies to maintain a sustainable business and push their products onto the Swiss market on their own.

This project is a continuing dialog that aims at rendering visible the already existing, yet overlooked practices on site while re-attributing value to their process. It func- tions as an ongoing program of modification within the hotel framework that will better profit from the existing socio-cultural resources. A series of action and interven- tion varying in time and scale will generate a never-en- ding dialogue between the hotel and its actors in order to sustain change by fostering a light but durable change in the long term.

While remaining non-disruptive, a series of small-scale actions will reveal the value of the existing practices. With simple mean such as improving access to, or re- locating existing programs, light programmatic change will spread throughout the hotel while empowering their actors. New processes will be creating along the way al- lowing for the emergences of new relationship between the landmark and the social life of Zürich.

As the city of Zürich is growing, the industrial and publicly not accessible areas, such as the site of the Engrosmarket, are moving closer to the city center. How do we, in future, deal with such areas which are ideally situated for their main function as a distribution center but at the same time within immediate proximity to residential quarters?

By implementing regulating elements such as doors, stairs, lights, the site is transformed into an environment where public events such as concerts, flee markets, food festivals can take place at certain times during the day and week. These performative elements refer to existing elements found on the site allowing the Engrosmakert to function as a highly specialised machine for distributing fresh goods. Through re-interpreting these elements in a new way and repeated implementation, the Engrosmarket is being transformed allowing public functions to take place at certain times and thus be integrated in the network of the city.

The design proposes the conversion of the former parking garage of CIBA (Chemical Industry Basel). Today, the building is owned by Novartis and can only be used by its employees. The building is the only one of the available buildings situated on public land. Following the imminent departure of Novartis, the building is expected to be subject to the so-called „Heimfall“, whereby it will become property of the city.
The context is characterised by a high rate of foreigners, young people and low-income earners. The existing neighborhoods are organising themselves surprisingly well despite difficult conditions. There is a strong liveliness, which can be observed in numerous social and cultural institutions and their high frequency of visitors.
With the planned reorganisation of the former CIBA area, large-scale changes and gentrification processes are to be expected, which will lead to rising rents and eventually displacement.
In order to provide the local people with a public space of opportunity, a "Volkshaus" for Klybeck is to be initiated as an interface between the existing and new developments. In the spirit of the "Volkshäuser" of the emancipatory motivated labour movement around 1900, the project is organised on its own initiative in the form of a newly founded association.
In order to support the process of appropriation by the users, a temporal factor is included in the project: at no point should there be an end to the design process. Uses and interventions influence each other, the project is constantly in motion. This also corresponds to the structural logic of the existing building. The ramp system of the double helix emphasises a continuous space, which becomes a place of community. The regular structure of the building is overlayed with specific situations on a human scale. The monumental structure stands self-confidently along Horburgpark and uses its existing representational power.
