The “Hausentwurf Studio-Loft” (house design) of the OKAL Haus GmbH is focused on high-quality materials and renewable raw materials. The woods used come from PEFC-certified forestry. It is the first single house which has been certified with a silver badge from the “Deutsche Gesellschaft für Nachhaltiges Bauen”. Besides latest technology, the house impresses with its design. The room height of 2.8 m creates comfort and well-being. Central technical functions can be easily controlled by a central system. The intelligent building automation system myGEKKO is part of the OKAL houses’ standard. A clear zonal division and a maximum of freedom of design belong together here. Thus, the “Studio-Loft” enables living and working under one roof.
