Weinlager

The Weinlager is an innovative adaptive reuse project in Basel's Lysbüchel neighborhood, completed in 2023 by Esch Sintzel Architekten. This former Coop wine storage facility from the 1950s has been transformed into a vibrant residential complex comprising 64 apartments of various sizes and typologies, along with communal amenities including a café, commercial spaces, guest rooms, a common room, roof terrace, and music rehearsal spaces. The most distinctive feature of this conversion is the preservation and showcasing of the building's massive mushroom-shaped columns, which tell the story of its industrial past. These structural elements have been deliberately exposed and staged throughout the building, creating a unique spatial experience in both the apartments and the two 'rues intérieures' (internal streets) that run lengthwise through the building. The project embraces sustainable principles by reusing the existing concrete structure, which significantly reduced embodied carbon. New additions include earthquake-resistant head structures and green steel skeletons with balconies flanking both sides of the building. The renovation also prioritizes energy efficiency through Minergie-P-Eco standards, with approximately 60% self-sufficiency in energy and heat production. Initiated by the Habitat Foundation, which acquired part of the Lysbüchel industrial neighborhood in 2013, the Weinlager project stands as a remarkable example of how industrial heritage can be repurposed to create inclusive, sustainable housing while preserving architectural character and history.
