Haus ohne Eigenschaften, Architectural heritage monument in Müngersdorf, Germany

The Haus ohne Eigenschaften is a two-storey cubic rendered house at Kämpchensweg 58 in Müngersdorf, built to plans by O. M. Ungers and completed in 1996. It has a rectangular plan with no visible roof edge, developed from inside out around a central square hall. The long sides have four axes, the narrow sides two, each divided symmetrically by tall double doors. Inside are walls in stucco lustro and floors of limestone, terracotta and walnut parquet.

Architect Oswald Mathias Ungers completed this building in 1996, aiming to realize pure geometric forms without representation. This work follows the principles of minimalist architecture that intentionally departs from traditional residential conventions.

The name echoes Robert Musil's novel The Man Without Qualities. The house was built for Ungers himself, and its interior uses stucco lustro walls, limestone, terracotta and walnut parquet flooring. The former basement pool and massage rooms now house the library of the Dr. Speck Literaturstiftung.

The house at Kämpchensweg 58 is a private residence and a protected monument, so it can only be viewed from the public street; there is no interior access. The two-storey cube has no visible roof edge, and its long sides show four axes while the narrow sides show two, each centred on tall double doors. The lower level, once holding a swimming pool, now houses the Dr. Speck Literaturstiftung library.

The house's name plays with the idea of having no properties or characteristics - it presents itself as living space stripped of unnecessary features. This conceptual provocation makes the building a thought experiment where the absence of detail itself becomes the message.
