The Skybox features 75 square meters of living space along with two bedrooms. The plot on which the house is located is a partitioning of a larger plot belonging to an old thatched house and is partly enclosed by trees.

The two buildings share a common garden, and the layout provides both separate and common spaces for the houses. The design ensures that the house gives off an illusion of being spacious,

The bedrooms are situated apart from the large living space and open to an open hallway. Diagonal views stretch out through the whole building. The house features minimum ceiling height, and “sky-boxes” are added to provide space and air. The large glazed openings provide a view to the sky.

The house features sliding doors so that house owners can be one with nature, by shutting the doors to the house.

The balloon frame construction sits on the exposed concrete base. Oak lists of 30x30mm wrap the building. The lists are treated with iron sulfate, which darkens and enhances the structure of the wood. Floor boards are also featured in oak. Heating is provided by a heat pump integrated in the wall, reducing heating costs and carbon dioxide emission.

The sky-boxes ventilate the space trough natural chimney effect. A cast iron stove is incorporated for additional heating. The project is both designed and build by Primus architects for client Jakob Lundsteen and Susanne Mahler.
