The solar pavilion stands as a sort of backdrop to the stately private estate on Lake Walen. Beneath a lightweight, 50m² solar roof, there is space for two heat pumps to supply the entire estate, as well as two electric cars. The cars’ batteries are activated to store solar energy. On overcast winter days, the energy stored in the car batteries can be fed back into the heat pumps, thereby reducing dependence on the electricity grid.

This prototype small-scale building follows a radical design logic and is constructed predominantly from prefabricated components in standardised dimensions. A few bespoke solutions complement the generic design and enhance its structural and spatial potential. No component is cut to size, and no joint diminishes the material value of the resources used. This has resulted in a distinctive, light-weight aesthetic.
