The modern Plusenergiehaus Annen is located in a development zone in Farschweiler, on the edge of a large forest. The developers’ goal was to create a contemporary aesthetic while upholding the principles of sustainable design. Built of concrete and wood on a hillside, the compact design meets high standards for environmental protection and building biology.
Revolutionary positive-energy house on a hill
The site is located on a northern slope with a beautiful view of the forest. The positive-energy house is a building that produces more energy than its users consume. Annen is designed to save about 75% more energy than a standard passive house.

The house uses sustainable passive-home technology: excellent thermal insulation, triple-glazed windows, and controlled ventilation with heat recovery. The south-facing roof is equipped with photovoltaic and solar thermal systems.

The 2011 project was intended to support economic and environmental development while conserving resources. Its goal was to make the household less dependent on the negative effects of globalization.

The architecture and interior design are tailored to the requirements of new technologies. The two-storey house offers 317 m² across two levels. The main living and dining area is open. The basement is partly built into the ground and made of exposed concrete. The upper floor and roof are made of durable wood.
