House BS

Conversion and extension, Hohen Neuendorf, Germany

The new relationship between inside and outside, architecture and nature, form the design theme for the conversion and extension of a house for a family of four in Hohen Neuendorf near Berlin. A new structure was added to the existing house from 1925. A visual axis connects the old and new building and creates a new sequence of spaces from the private rooms, through the hallway, kitchen, living and dining rooms, to the garden.

The existing house is part of a historically grown development structure along a lime tree-lined street in the old town center in Hohen Neuendorf. The deep lot has a number of space-forming existing trees, such as an Irish yew (Taxus baccata) and a hornbeam maple (Acer carpinifolium), whose preservation provided the inspiration for opening the house to the garden.

The extension, which houses the living and dining rooms, is placed against the garden-facing gable wall of the house. The old and new buildings are made visible through glazed building joints. On the entrance side, the extension forms a façade alignment with the vestibule, allowing visitors a view through the new building into the depths of the property as they enter the house.

A wide wall opening connects the elevated kitchen with the living and dining room at garden level. From the elevated vantage point of the kitchen, the nine-meter-wide glass facade of the living room seems to fill the entire width of the property. Exposed concrete surfaces, polished screed flooring and a solid oak staircase define the materiality of the interior. On the outside, the new building is clad in light-colored wood siding. The roof area is designed as a green roof. In the old building, the wooden floors were partially preserved and partly supplemented with white oiled Douglas fir floorboards. The existing staircase, windows, doors and fittings were refurbished.
