The private client convoked a proper architectural competition for five invited offices, the idea being to choose an architect for his new residence.
The residence is situated in a new neighborhood of six larger villas. The unique feature of the site is a splendid view of a stand of oak trees that are over a hundred years old. The terrain slopes down towards these trees. To guarantee that most of the major spaces will have access to this view, the house is organized in stepped levels following the terrain. The outline of the house keeps to the shape of the plot of land, minus four meters all around, the minimum distance Slovenian law calls for vis-à-vis one’s neighbors.

The heart of the house is an external covered courtyard. Main spaces such as the entrance lobby and staircase, the children’s playroom, the dining, living, bedroom and work areas overlook this space. These rooms, plus the wellness area with its small pool, also have a view of the park.
The staircase roof is glazed. The courtyard roof is part-glass, part-wood and has views of the sky and the treetops, thus creating a strong link between inside and outside.
Structurally, we wanted to achieve a column-less ground floor. The ceiling of the dining and living area is slung from a Vierendeel beam hidden in the walls of the floors above. The glass construction and frames are also handled with minimum supports.
Other programs inside the house follow the client’s brief, which was very precise. His is an interesting lifestyle, what with working partly at home and having different hobbies. Security and fire escape issues are important, as is the clear division of private areas of the house and those where guests are allowed to wear shoes or where one receives the postman.
The house has also to be “intelligent”. Various functions such as air conditioning, security and sun-responsive external shade can be controlled by software, and different ambients can be created using lights and music.
Sustainable issues
The house is a private residence positioned in the neighborhood of 6 larger villas. The quality of the site is a beautiful view to the existing common park with oaks over 100 years old. Therefore the aim of the building was to open view from all main spaces of the house towards these trees.
The building is constructed in half-floors. In the heart of the building there is a stepped courtyard, where all the main spaces open.
