The Lysbüchel site in the north of Basel was originally used for commercial purposes. Since 2017, an architecturally diverse residential area has been developed in the southern part of the site. The owner, Habitat, subdivided the site into 15 plots, 12 of which were transferred to housing cooperatives under building rights agreements. The strip where "Lyse-Lotte" now stands formerly served as a buffer zone between the fragmented perimeter block structure of the St. Johann district and the adjacent commercial buildings.

Lyse-Lotte is a residential building for approximately 40 occupants. The collage-like result serves as a symbol of participatory architecture. The building comprises a basement level, four storeys above ground, and a roof level. Communal areas include the garden, the entrance hall, and the roof, which features two structurally independent additions used as a greenhouse and a guest apartment respectively. A large, partially covered and landscaped roof terrace provides additional shaded communal outdoor space.

Reflecting the diversity of its cooperative ownership, the apartment typologies and layouts vary accordingly. Large family units are stacked above LEA-certified, barrier-free, age-appropriate gallery-access apartments, while the oversized base volume accommodates double-height live/work studios. A flex room accessible from the communal hall responds to contemporary living and working requirements.
