This apartment building with 70 residential units got built in Dortmund‘s district „Kreuzviertel“. The building is architecturally divided into four sections, with bay windows and a full height glass joint that sets the building stylistically from the surroundings. With this building an existing gap on the main street got closed: The courtyard area got transformed into a green and quiet oasis. A bright and transparent architecture opens up to the garden and an impressive tree population can be experienced. A successful mix of different apartment sizes enables the house to suit different resident typologies. Almost all units are accessible, and the building has an underground car park with direct access to the apartments. One of the main focuses of the design was to create a healthy living environment. Natural substances and materials are used. Renewable energy resources got applied by the planning process.
