This is a home for a young family located in the suburbs of Prague. The terrain of this property slopes slightly away from the driveway, allowing us to locate the parking on the roof of this one-story home, which leaves the main part of the house not visible from the outside except for a volume of the garage. On the ground floor, four separate wings each with different functions are connected in the main hall which accommodates a curved concrete staircase, a main entrance to the house. The rooms in each wing are connected along a single corridor providing a vista through the entire suite of rooms. The enfilade serves as a walkway through the house as the spaces spread out one after another. Four separate wings divide the parcel into four respective gardens with like rooms facing the same outdoor space and therefore each garden has a specific character. The entrance garden and main social garden are planted with trees and will eventually develop into a lush park-like setting. Private gardens, on the other hand, are designed as enclosed atriums. The house is a concrete building. The concrete staircase and peripheral load-bearing wall are exposed in a raw form, while other walls and floors are polished white. For the bathroom and swimming pool cladding is used a natural stone, whereas for wardrobe paneling and fixed furniture is used wood veneer with special attention to fine detail.

The house is covered with earth on the north side, while most of the rooms are oriented towards the south. In winter the house is heated by a geothermal heat pump combined with underfloor heating.
In summer the house relies upon airflow, shading, and thermal mass to control internal thermal comfort, combined with the heat pump cooling system when needed. The extensive green roof and energy-efficient glazing helps maintain thermal comfort inside the building. All roof water is gathered into a storage tank for further use.
