Steinenvorstadt 5, Basel – Renovation and Adaptive Reuse
The project transforms Küchlin’s Variété into a building with 40 apartments and commercial spaces while preserving the strong rhythm of its original façade. The west and east elevations retain their distinct characters: the west-facing broad street frontage remains bold, while the east-facing narrow alley anticipates a greener, more residential character. The sloped roof over the first attic floor is retained, contributing to the building’s energy performance, while the flat roof is reimagined as an intensive rooftop garden – a lush, enclosed green space.
Seven above-ground and five underground levels accommodate diverse uses. Internal circulation is adapted to each level: flexible escape routes in the basement, and centrally located stairwells and lifts upstairs maximize daylight, accessibility, and efficient layouts. Apartments emphasize spatial efficiency and careful use of façade openings.

Der Entwurf des neuen Stadions integriert sich harmonisch in die umgebende Landschaft und Topografie. Die Gebäudegeometrie greift die charakteristische Flächigkeit des Sportparks und des Mauerparks auf und überführt sie in ein zeitgemäßes, barrierefreies Konzept. Der historische Kontext bleibt für die Nutzer erlebbar. Der zentrale Boulevard verbindet das Stadion mit den Sportpark-Gebäuden und schafft eine attraktive Begegnungs- und Aktivitätszone. Das asymmetrische Stadionvolumen öffnet sich zum Boulevard hin, während die Erschließung durch zwei Rampen entlang des Trümmerhügels eine uneingeschränkt inklusive Zugänglichkeit für alle Nutzer gewährleistet.
