House O sits upon a hill in a beautiful small village situated within the district of Potsdam-Mittelmark, on a unique site that takes in breathtaking scenic views over the nearby lake.

The surroundings are dominated by a composition of historical and modern mansions, nestled within large well-established trees. As much as possible, the natural landscape has been preserved on the site in keeping with the sensitive location.

The design concept for the façades plays with the contrast of ‘open and closed’, drawing upon the importance of natural perspectives into the immediate surroundings. The narrower sides of the building are glazed toward the south into the garden, and toward the north, revealing a magnificent view over the lake. The west and east façades to the neighboring sites are mostly closed, with the large prefabricated concrete elements remaining solid against narrow glazed bands that let additional light into communal spaces. The building’s interior appears light, bright and welcoming, transparent and open as a result of fully glazed south and north facing façades. During the change of each season, the towering deciduous trees create natural walls of color, allowing the interior experience of building to continuously vary along with the natural landscape that surrounds it.

  • Winter – panoramic view, bright sunlight
  • Summer – closed tree canopy with focused views, shadows with diffused sunlight

Geothermal energy is used for heating throughout, and integrated with BuS technology that allows individual control and adjustment of each space for exceptional comfort and environmental control.
