At the heart of Oensingen, bonainvest has developed the Roggenpark project with three residential and commercial buildings and a nursing care home on an area of some 7500 m2 for the Gäu Senior Citizens’ Care Cooperative (GAG), together with the citizens’ and civic community.
The location at the heart of Oensingen has enabled a medical practice, a bank as well as a hairdressing and beauty salon to be integrated into the Roggenpark.
As an open total contractor, bonainvest built the centre providing specialized services for the elderly with a residential nursing home, a Spitex support point and a café run by the GAG.
The project was completed in cooperation with the bfb ag architects’ practice of Egerkingen. The buildings are Minergie certified. The project uses district heating supplied by the local district heating alliance. In addition, the apartments comply with bonacasa construction standards.
