The residential project ”Ecological living at Dreisbach-Park“ is located near the city of Siegen, in a district of Netphen, in the center of Dreis-Tiefenbach. The aim is to develop a flexible, future-oriented residential living area that focuses on assisted living. The main users are active seniors who would like to live in a communicative environment and achieve an improvement of living quality due to the offered services. The project will also provide great living qualities to families or students, developing a vivid mixture of different generations. The heart of the design is the Dreisbach-Park, a public green space that invites to go for a walk and rest. Along the main routes are accessory service institutions, which contribute to the revival of the park, such as a park café, a library and areas for other outdoor activities. Because of its open structure the planning concept integrates itself into the structure of the urban context. Perspectives into the well-known neighborhood and within the neighborhood are possible due to the locations of the buildings. The new district is developed as a zero-energy-project. The entire required energy per year is exclusively produced by renewable energies like photovoltaics and geothermal energy.
