Sanierung Überlandstrasse 375/377 und 391/393

Short description

The two apartment buildings from the 1960s with a total of 180 apartments are in great need of renovation and refurbishment.

The project

Through targeted intervention in the housing structure, it is possible to adapt the housing mix to local demographic developments and demand, thereby improving vacancy rates and opening up to opportunities.

With the developed refurbishment concept, it was possible to ensure an economic refurbishment with current income and socially acceptable housing without exceeding the market standard supply rents. The preliminary work carried out, with detailed planning of the kitchen and bathroom and specific offers, allows the extension and quality to be visualised and the corresponding costs to be secured.

With an attractive basic variant and various optional modules, a tailor-made renovation project was implemented together with the owner.
