• Collaboration with a local partner.

Bochum / Garmisch-Partenkirchen, 1 October 2025 – Using a modular approach, Vonovia has started modernising 74 apartments in the Upper Bavarian town of Garmisch-Partenkirchen. The 13 buildings, all dating from 1975, are currently rated in energy efficiency classes F to G. After modernisation, they will be upgraded to class A.

Yesterday, Vonovia CEO Rolf Buch, Bavarian Housing Minister Christian Bernreiter and Claudia Zolk, Deputy Mayor of Garmisch-Partenkirchen, were given a tour of the project at the Vonovia residential complex on Steigfeldstrasse in the Burgrain district.

“By using sustainable building materials and a high degree of prefabrication, we can accelerate the modernisation process. This efficient modular approach is a highly effective tool for meeting our ambitious climate targets,” says Rolf Buch. “It enables us to drive a sustainable and efficient energy transition in our existing building stock, while keeping rents affordable for our tenants.”

In renewing the buildings, Vonovia primarily uses prefabricated, insulated timber modules, fitted on site to the walls like tailor-made suits. Key elements of the project’s sustainability are the use of renewable materials and collaboration with local partners.

“This project shows how innovative solutions can drive the energy transition in existing residential areas. Working with local partners and using regional materials is another key element in achieving long-term sustainability,” says Christian Bernreiter.

Modular prefabrication means that construction work in the residential area will be completed far more quickly than in a conventional modernisation project. Triple-glazed windows and new doors are also being installed. The windows feature integrated indoor ventilation with heat recovery, helping to save energy. The indoor environment is further enhanced with the use of integrated blinds and sun protection glazing, and a photovoltaic system is being installed on the roof to generate green electricity.
