Architecture as Guest: Preserving Territory, Inhabiting the Landscape.

As part of the expansion of the «Sonnenfeld» residential development in Oberwil, located on Bielstrasse, we participated in an architectural design competition. Our proposal was recognised as bold, provocative and thought-provoking. For us, this provided an opportunity to reflect on the relationship between territory and architecture and to ask what responsibility architecture must assume within this context.

Territory as a Cultural Framework. Territory is not a neutral backdrop upon which architecture can be placed at will. It is a complex framework of landscape, settlement, infrastructure and human appropriation. More than a geographical space, it represents a living environment shaped by cultural, ecological and social forces, where nature, society and the built environment continuously influence one another.

Architecture therefore always operates within a broader context. Every intervention becomes part of an existing network of relationships and carries responsibility towards the place itself, its natural environment, its resources and the people who inhabit it. The central question of our proposal was therefore: How can the necessary densification of our built environment be achieved without depriving a place of its identity through excessive transformation? Or, put differently: How can we establish an Architecture as Guest that inhabits the territory with presence, yet without domination?

The answer does not necessarily lie in refusing to build. Rather, it lies in an attitude of precision, restraint and careful consideration. If territory is understood as a sensitive structural framework, designing means first and foremost reading what already exists, minimising intervention and developing the inherent qualities of a place.

Our proposal for the Living and Dwelling in Sonnenfeld project is grounded in precisely this approach:

  • No basement construction and no lifts: By deliberately omitting these elements, we avoid the extensive excavation that, in conventional developments, irreversibly disrupts the ecological balance of the soil.
  • Elevated construction: Raising the buildings above ground reduces soil sealing to an absolute minimum, allowing the landscape to continue uninterrupted beneath the structures.
  • Screw pile foundations instead of concrete slabs: Rather than suffocating the ground beneath large concrete foundations, the buildings are anchored only at carefully defined points.

The buildings touch the ground only where necessary, behaving like respectful guests within the landscape – present, yet never dominant.

Sufficiency: Achieving More with Less. This way of building is not merely a technical or constructive strategy; it expresses a particular understanding of dwelling. Living, in this context, does not mean taking complete possession of the land, but becoming part of an existing cultural landscape. Because almost every landscape has already been shaped by human activity, every new intervention demands an awareness of proportion, respect and appropriateness.

At Sonnenfeld, this attitude becomes spatially tangible. Rather than seeking complete control over the site, the architecture strives for a balance between use and preservation.

The decision to forgo basement storage and an underground parking garage follows the same logic. Features that have become standard in conventional residential construction require substantial interventions into the ground, the topography and the material cycle. Eliminating these components not only reduces construction costs and embodied carbon, but also encourages a more conscious relationship with space and material possessions. Alternative solutions – such as decentralised storage units, utility rooms and generous outdoor spaces – demonstrate that residential quality does not depend on technical over-equipment, but on intelligent organisation and spatial generosity.

Sustainability as a Design Attitude. The project naturally brings together ecological, economic and architectural qualities. Sustainability is not treated as an additional layer, but as the direct consequence of a design approach that respects the territory. Our proposal demonstrates that density, comfort and identity can be achieved without extensive soil sealing, underground infrastructure or excessive material consumption.

The landscape remains intact, the intervention remains reversible, and architecture becomes part of a larger whole. In doing so, the project formulates a contemporary yet fundamental architectural position: our task is not to occupy territory, but to inhabit it with care.

We are fully aware that such an approach depends on the specific conditions of each individual project and cannot be applied identically in every context. Nevertheless, we regard Architecture as Guest as a guiding principle that informs our thinking, planning and design process at every stage. It is an attitude that continues to shape our work.

Inspiration you can touch – a glimpse into our analogue architecture library

Pinterest, digital mood boards, Instagram, ChatGPT and other AI-powered research tools – the number of digital information platforms is vast, and they’ve become an integral part of our daily workflow. And yet, our analogue architecture library possesses a unique power of its own. As a tactile archive of architectural history and a source of inspiration for future thinking, it remains a constant presence in our studio – sometimes used more, sometimes less, but always accessible.

Minergie certification for Andermatt

In the heart of the Gotthard massif lies the small village of Andermatt, which despite its striking location remained untouched by tourism for a long time. Thanks to a comprehensive tourism initiative by the major Egyptian-Montenegrin investor and developer Samih Sawiris, this has now changed and Andermatt has become an attractive destination for winter and summer visitors. We were also involved in this project and, as architect and general planner, have been responsible for getting the largest flat block there, Haus YARA, off the ground in recent months. Our guiding principle for this project was to combine tradition and modernity in order to create a harmonious whole between contemporary living and traditional architecture. MINERGIE certification, which was officially awarded the week before last, is also part of the concept.

Sustainable Building Practices

Sustainability in the construction industry is one of the key challenges of our time, while also offering significant opportunities to shape the built environment responsibly and with a long-term perspective. It is a topic that we engage with every day. Whether working on private or commercial developments, small-scale interventions or large, complex projects, the many dimensions of sustainability are an integral part of our planning process and influence a wide range of project tasks. They continue to shape the way we design, plan and build.

In Focus: Interview “Bird Conservation in Urban Areas” (Part 1)

The topic of green roofs and biodiversity conservation in inner cities has gained increasing importance in recent years and is becoming a key component of sustainable urban planning. As an architectural practice, we regularly engage with this subject, for example through our work on the Stücki Park project on Hochbergstrasse. This provides good reason to take a closer look. In line with our credo “sharing experience”, we aim to gain deeper insights into why urban greening and bird conservation are so important and what role Basel plays in this context. We spoke with two experts on the subject. We begin with Dr. phil. nat. Jean-Pierre Biber from the Advisory Office for Bird Issues, Department for Nature and Landscape Conservation of the Canton of Basel-Stadt.

Analog Despite Digital: The Significance of Architectural Model Making in a Digital World

A large part of our work today is digital and virtual—we design with CAD, enhance plans with BIM data, and visualize projects in 3D. Still, sometimes the tried and true methods prove their worth. Take model making, for example, which continues to play a significant role in architecture. Surprisingly, this might seem counterintuitive given the indispensable tools like 3D renderings and simulations, making physical model making appear almost outdated. However, as in life, the magic often lies in the mix: combining digital and analog methods unlocks unique potential. Why Analog When Everything Is Digital?
