Within the scope of the site development of the Kunz Spinning Mill in Windisch, a usage study for assisted living was carried out for the Rohn building, which was previously used as a recruitment centre. The building was completed in 1960 as the last building of Roland Rohn’s spinning mill ensemble. Integrating the new uses into the existing building structure only requires minor modifications. There is space for 48 rooms along the north and west façades. Six residents each form a living group, which is assigned its own common room. In addition to group accommodation, areas for workshops, staff and administration, utilities and common rooms are planned. The gym in the basement is to remain.
