Mountains in Sight

Low-energy housing complex, Leonstein (AT)

The low-energy housing complex fitted with EGGER OSB and DHF was built in a green environment with a view of the mountains.
In Leonstein (Grünburg), Holzbau Aigner GmbH has built a housing complex that consists of four semi-detached houses with eight residential units that were erected using the timber frame construction method. The low-energy housing complex is a true family project: The planning included ideas from the senior boss Anton Aigner, as well as his two sons: Joachim Aigner, managing director of the company, and Michael Aigner, an architect.

Fitting it with a heating system using geothermal energy through energy columns required a high initial investment, but the costs of water and electricity can be kept low as a result. The wood-based materials EGGER OSB 3 and DHF were selected for the wall construction of the residential units. The resin-bonded OSB board was used for the interior walls and the vapour-permeable fibreboard DHF as external wall cladding underneath the larch façade.
