The Gemse Apartment House is located in the midst of the touristic village of Andermatt (CH), which – as a result of the custom-made real estates, hotels, leisure- and sports activities – has developed into a favoured all-year round holiday destination.
This building sets new benchmarks when it comes to multi-storey timber construction and thanks to the harmonious blend of timber and glass it creates a very pleasant and light-flooded atmosphere. South-facing, spaciously designed window areas and sunny balconies with direct view to the Ursern Valley promise tranquillity and recreation.
The supporting structure of this modern apartment house, which comprises a total of 19 holiday accommodations with flat sizes ranging from 35 to 265 m², was built as timber frame construction with upper ceilings made out of cross laminated timber elements. Natural stone cladding has been provided for the first floor of this timber construction façade. As far as building physics were concerned, the most important aspect was to fully comply with the high requirements in terms of acoustic and fire insulation. In addition, high resistance against prevailing extreme climatic conditions had to be secured – above all with respect to the high snow
loads, which may partially achieve values of more than 1,000 kg/m². In order to secure the transport of the individual, factory pre-fabricated elements, the size of the elements had to be adapted taking into account the very narrow serpentine roads and
a detour through a railway tunnel.
This building project serves as perfect example of how to benefit from synergy effects within the Rubner company group. The company Rubner Objektbau, acting as general contractor, executes this building on behalf of the client as all-in-one turnkey solution. Rubner Holzbau supported the associate company in the fields of planning, production, and assembly of the entire supporting structure, composed of wall, ceiling and roof elements, which were pre-fabricated in the factory site of Ober-Grafendorf.
