2104 Altegg

The property is located outside the city of Lucerne in a slightly elevated position with a view of Lake Lucerne and the surrounding mountains.

The existing building had considerable energy and architectural deficiencies and did not meet the client's requirements, which is why they decided to build a new replacement. The existing basement with ancillary rooms was retained and extended with a garage parking space. The existing garden level was demolished and replaced by a new building.

The new and larger garden level houses the bedrooms, a kitchen with dining area, a spacious living room and two bathrooms. The living and dining area has an all-round glazed view of the lake and the mountain landscape. The outdoor terrace with generous canopy and steel supports on the outside as well as the inner courtyard give the conversion a pavilion-like character....

The restrained interior is characterised by Travertine, white plastered surfaces and bronze oak. A traver-tine-clad fireplace divides the living and dining room as a central spatial object. Oak as a building mate-rial appears on various small components such as furniture, fixtures, cupboard fronts and railings.

In addition to a sustainable building technology concept with heat pumps and a solar system, the design emphasises the careful selection of materials and their grey energy and transport routes. The basement was retained and merely renovated. The garden level was built in timber construction with local woods.
