Kirchberg, Switzerland

The spatial situation of the Sonnegrund care home in Kirchberg, built in 1990, no longer corresponds to contemporary requirements. The brief comprised of, on one hand, the reorganisation and extension the care and support facilities and, on the other hand, the renewal the technical services. The proposed extension continues the logic of the existing buildings. The new wings follow the outline of the existing basement to avoid new excavations and allow the re-use of the existing structure of the basement. The added volumes give form to two outdoor spaces, the entrance courtyard and the Hof, which order the outside spaces and the site.


Similar to the the existing building, a sloping roof is proposed for the new additions. The new roof is located above the residents' rooms and, thanks to its inclination, creates a bright interior and spatial richness. A harmonious coming together of old and new is created with a volumetric granularity that is appropriate for its context.

The proposal is conceived as a flexible structure, due to a clear structural arrangement. The rooms on the ground floor can be connected to each other or separated into individual rooms, depending on their use. The rooms are arranged along a spacious and well-lit corridor, which serves as a place for the residents to stay and meet. The slight tapering and widening in the corridor create a versatile and rhythmic spatial experience.
