Haus Freudenberg, Single-family residence in Nikolassee, Germany.

Haus Freudenberg is a two-storey brick villa at Potsdamer Chaussee 48, built 1907–1908 to a design by Hermann Muthesius. Its L-shaped plan follows the bend of the Rehwiese: a high gable and steep hipped roof sit over dark red Rathenow hand-struck bricks with white joints, and a half-timbered gable crowns the entrance axis. Inside, an oval stair hall linked the family rooms on one side with service and children's rooms on the other.

Architect Hermann Muthesius designed and built this house between 1907 and 1908 for merchant Hermann Freudenberg. The building reflects early 1900s residential traditions in Berlin's wealthy Nikolassee neighborhood.

The house was built for a family with four children and a lifestyle geared to entertaining, and its plan reflects that: a central oval stair hall links the living rooms to the left with the dining room, service rooms and children's quarters to the right. The original interior, now lost, used mahogany, beech, lemonwood and maple panelling, ceramic and glass tiles around the fireplaces, and marble in the conservatory.

The house stands at Potsdamer Chaussee 48; only the entrance avenue of the former garden survives, leading from the street to the building. The grounds behind it were built over with the Nikolashof terraced housing, so the house is seen from the public street rather than from a garden. The interior was divided into eleven flats in 1975 and is not open to visitors.

In 1975, the house underwent major renovations and was divided into multiple residential units. This conversion shows how private homes adapted to changing living arrangements.
