Energetic and formal redevelopment of a detached house


energetic renovation of a detached house with an annex from the 1960s


After installing a new heating system and renewing the windows, an inspection of the roofs revealed obvious leaks in the air-tightness and sealing levels. In the course of the necessary renovation, the entire building shell was included. The opportunity was taken to formally modernize the outdated building, optimizing the building's cubature, reducing external wall projections and integrating oriels into the thermal envelope. The extension, which was built about 10 years after the year of construction of the main building, was included in the overall design and thus part of the overall ensemble. The roof was provided from the outside with intermediate rafter and on-roof insulation while retaining the existing load-bearing structure, and all exterior walls were fitted with curtain-type, rear-ventilated facades in plaster or zinc sheet cladding. The building also received a PV system with solar storage. The result in this exposed location in the vicinity of a grown single-family house settlement in the north of Aachen is particularly characteristic of the exterior space, so that the building was open to the public on 29 June for the "Day of Architecture 2019" and smd+ was available to numerous interested visitors for questions and answers.
