A dedicated installation team handles all aspects of the project, from earthworks and electrical work to roofing, grant application, and heat pump installation.

We are extremely happy with our bathroom renovation. Many thanks to Ms. Linnenbrügger and her team.

We would especially like to thank Mr. Mohammadi, who, together with his team, ensured that all work was completed on time. Furthermore, all our questio
