"Waldhäuser" East, Tübingen

The Waldhäuser Ost housing estate, built in the 1970s, is undergoing comprehensive energy efficiency upgrades and careful redevelopment. The location of the building in an earthquake zone poses a particular challenge, as it does not allow for classic building extensions under normal static conditions. The necessary earthquake safety is therefore achieved through targeted measures to reinforce the building: Reinforcing balcony walls and additional northern extensions take on load-bearing functions and at the same time enable the creation of additional living space.

Two of the three building sections will be extended using lightweight timber construction. This method reduces the dead weight of the structure while also meeting high standards of sustainability and cost-effectiveness. In order to retain the existing residents in the long term, the energy-efficient renovation of the facade will be deliberately limited to the necessary extent. Serially manufactured, recyclable components are used; openings and balconies are based on the existing building in terms of scale and appearance. In this way, structural improvements can be made without triggering a noticeable increase in rent.

The energy efficiency upgrade of the building envelope is combined with an extension of the balconies and a new, contemporary color and facade concept. In addition, northern extensions, additional stories, and the conversion of the existing ground floor and garden level apartments into maisonette apartments for large families will significantly expand and diversify the mix of apartments.

More generously designed outdoor seating areas and improved outdoor spaces also enhance the quality of life and strengthen the overall quality of living in the neighborhood.
