House Behind a House

The compositional structure extending in four directions creates smaller spaces, permeable to the outdoors and designed for different uses and lighting conditions. To the east, an intimate space with a thermal pool. To the west, a terrace connected to the dining room. To the north, an attractive garden with water features that is visible from the living room. To the south, a roof garden in front of the bedroom.

The light wooden structure is based on steel ground screws, delicate pins with minimal groundwork and no use of concrete. The entire load-bearing structure - walls, partitions, ceilings and floors - is built of laminated spruce beams. Laminated boards are used for built-in furniture. Energy-efficient thermal insulation is achieved via a combination of wood wool and a ventilated façade, which omits the need for vapour-proofing. The calculated heat transfer coefficient of the perimeter structure is U = 0.16 W / m2K. The house’s energy efficiency is supported by wooden windows with insulating triple glazing. Natural fibre-cement façade panels ensure that the all-wood structure is fire resistant, which allows for its erection on a small plot, in close proximity to neighbouring structures.
