PROPOS is developing a residential complex for upscale requirements in Essen-Kettwig: The historic villa Am Bögelsknappen 1, which is characteristic for Kettwig, is being renovated and supplemented by two elliptical wood hybrid buildings with underground parking. A total of 43 residential units are being built on a slope, and a fossil-free energy supply is part of the concept in KfW standard EH 40 NH. The historical heritage is preserved, the new buildings step back in height. The project “Am Luftigen” offers green living with a view of the Ruhr River, close to forest and park in a central location in the catchment area of Essen, Duisburg, Düsseldorf and Wuppertal.
