Client: Chandler KBS
Status: Building permit approved in 2021
Services: Service Phases 1 to 4 for 6 residential buildings (0,3 ha) - 24 existing and 12 roof-stacked residential units (ca. 870 m2)
CGI: Luppa

The building application comprises six buildings at Königsbergerstraße. The substitution of the existing roof with a 70° pitched one picks up on the traditional housing silhouette from the 50/60 ́s, makes it possible to preserve the appearance of a two-story building and at the same time creates a new full story. The modernisation of the facades and the proposal of more extensive balconies for the existing apartments on the ground and first floors convey a significant overall upgrade to the buildings. New greened parking spaces for cars and bicycles, new recreation areas and a network of pathways offer social engaging outside places for recreation. Energetically, the implementation of air-source heat pumps in each building, the improvement of the insulation of the exterior walls, the inclusion of Photovoltaic system on green roofs and the integration of surface rainwater drainage in the open areas significantly increase the energy efficiency and sustainability of the ensemble. The architectural and energetic upgrade of the buildings and open areas offer an essential reform and improvement of the neighbourhood.
