In the district of Langenhorn in Hamburg, family-friendly and high-quality apartment buildings are to be constructed on two sites in the south-eastern part of the area around the Ochsenzoll hospital as part of the OxPark development. The existing laundry building (Site 1) is being extensively renovated in close cooperation with the local Office for the Preservation of Historical Monuments. To create a harmonious ensemble of old and new, a bright, cube-shaped single standing building subtly negotiates the transition between the historic building and the SAGA (housing association) buildings to the west. The four-storey new building with underground garage contains a total of 16 residential units, consisting of 3-room and 2.5-room apartments, all facing south towards the park. Two L-shaped structures are positioned at right angles to each other on the area of Site 2, forming together with the neighbouring water tower the south-western boundary of the quarter. The four- to five-storey buildings have a total of 60 apartments of various layouts, which all enjoy at least one outdoor space, either a balcony or a small garden.
