In order to minimise the impact of building on the plot, the extension was built as an underground house- basically built into the hill.
We, with every project, examine how the placement of a building within the landscape affects its environment and how it interacts with/influences our personal space. By implementing solar systems and other passive energy resources our houses achieve the best possible energy performance.
The house is made of concrete, glass and natural stone. The large window which extends along the entire south facade of the house provides the underground house with light. The carefully and precisely calculated roof overhangs and protects the interior from overheating in the summer, but provides solar gains during the winter. It is extremely well insulated, which means it keeps cool in the summer but, in the winter, heats up nicely during the day with only average sunlight. The house holds the achieved indoor temperatures extremely well overnight thanks to thorough insulation. Barely any additional heating or cooling is needed.
