On the former extension area of the Jewish cemetery, the socially, sustainable and functionally mixed urban quarter WIR was created with five houses and 114 residential units in timber construction. The small, uniformly designed settlement consists of four to five-storey buildings, which form two courtyards and offer various meeting rooms with a swimming pool, physiotherapy practice, day-care centre, workshop, training restaurant and common rooms also to the surrounding area.

The neighbourhood enables a mixture of condominium and cooperative living. The four cooperative houses offer a colourful social mix of rented apartments, shared flats and cluster apartments for assisted living, dementia shared flats, senior citizens' and nursing home communities, youth welfare, children's living groups and housing for refugees.

The modular construction method of timber construction is based on a support structure that is uniform in all houses as a support system with solid ceilings. The standardisation on three building types and the extension with lightweight walls provides a high flexibility in floor plans and use and its future adaptability.

The building envelope achieves a very good U-value in the KfW 40 standard. The use of renewable building materials and recycled materials as insulation materials has a positive effect on the primary energy balance.
