2/2 – Inside, the house was brought up to the latest standards in line with requirements. The building envelope was insulated to Minergie standards, and the facade was clad with large Eternit panels. The property had the mortgage of no garden. The difference in height between the access road and the detached house was bridged by a steep slope that could not be used any further. A second building was now planned into this slope: In the basement, space could finally be gained for garages, a new access area to the property was designed and the room programme was supplemented with cellar rooms. The upper floor above accommodates 4 ½ generous rooms and ancillary rooms. In contrast to the upper house, the new building was materialised in exposed concrete as a counterpart. The greened flat roof is now also the garden of the original detached house. From both the garden and the attic terrace, the residents benefit from a beautiful panoramic view that stretches from the Zugersee across the Küssnacht lake bay all the way to Mount Pilatus.
