Der Blaue Wolf Competition - 1st Prize 2024–2026 This project has been on our minds for a while, and we are genuinely excited to share it. The Wolf freight station in Basel has been moving things around since 1876. The new housing project takes that history seriously. The existing freight halls no. 1 and 1a are carefully dismantled, every concrete element catalogued and assessed. Around 1500 tonnes of reclaimed structure are then bolted back together as the primary framework for five stacked double-storey halls. Reused SBB railway tracks and lightweight timber complete the picture for floors, balconies and spatial extensions. The whole system is modular and skeletal. Bolted connections throughout, no glue, no welds where avoidable. The building is designed to be taken apart again one day and reassembled into something new.

Der Blaue Wolf, 2024-2026, 1st prize 4-stage competition for circular housing with building component reuse, MF05 Areal Wolf, Basel, in revision Der Blaue Wolf is part of the new urban development of the former freight station - Wolf - in Basel. Since its inauguration in 1876, the site has been shaped by processes of movement, transformation and logistics: first as a marshalling yard, later as a freight depot for the handling and redistribution of goods. Today, this legacy of dismantling, shifting and reassembling is translated into a new architectural and social condition — a circular housing project. At the core of the project lies the careful dismantling and reintegration of the existing freight halls no. 1 and 1a. Their structural concrete elements are catalogued, assessed and reused as the load-bearing framework for the new development. Around 1500 tonnes of reclaimed concrete components form the primary structure of five vertically stacked double-storey-halls, preserving both material resources and the embodied energy of the site. Complementing this framework, lightweight timber construction and reused SBB railway-tracks are introduced as secondary systems for intermediate floors, balconies and spatial extensions. The project follows a modular, skeletal and reversible construction logic. Bolted connections and adaptable building systems allow the structure to evolve over time, enabling future transformation, disassembly and reuse. The project is currently under revision; final implementation remains subject to the ongoing planning and approval processes with the client.

Misting Structure, Verbier Built project 2025 A demountable steel ring for a pedestrianized street in Verbier, assembled for summer, removed at the end of the season. The circular beam is braced by a kite-shaped cable system, each mast leaning outward to keep the ring in tension. Bench prosthetics complete the installation, turning structure into street furniture.

Comme à la maison Competition - 1st Prize 2025 A childcare centre for children from 3 months to 6 years, designed around the scale and warmth of a domestic environment. Our structural contribution follows the same logic: load-bearing walls in stabilised raw earth, floors maximising local solid timber, and a deconstruction and reuse strategy for the existing building.

Punt da Piz Competition - 3rd Prize 2025 Prestressed gneiss, shaped by its own force flow. In a close dialogue between structural simulation and fabrication logic, the arch geometry follows the stress distribution through the stone sections.

Punt da Piz Competition - 3rd Prize 2025 Near St. Moritz, a flat arch bridge over the Inn, built from prestressed gneiss, a stone native to the region. Traditional masonry logic, contemporary structural thinking and fabrication.

Aaresteg Zehndermätteli–Bremgarten footbridge Competition - 1st prize 2025 Reimagining the Bernese cable bridge tradition: tension forces guided directly through solid steel sections, tracing the bending moment diagram into a slender, legible structure. The bridge embraces the natural asymmetry of its site: anchored into rock on one side, hovering lightly over the peninsula on the other.

Torre dell'Acqua Competition 2023-2024 Giving new life to an industrial water tower through a lightweight cable net, a helical staircase, a tube slide and a panoramic bar; all without touching the existing concrete structure more than necessary.

Building a lightweight pedestrian crossing at Munot Fortress in Schaffhausen. A simple intervention where technical details disappear into the existing architecture and landscape.

1+1=1 The project creates a symbiotic bridge where the existing structure and the new extension work together as one. An inclined central pylon on the island anchors both spans, ensuring stability through all construction phases, without temporary supports. The design frames views of the Rhône and the Alps, integrating into the landscape rather than dominating it. Over time, the old bridge can be replaced seamlessly, preserving a unified expression. Two spans, one identity. A bridge designed to adapt, evolve, and belong.
