New reception and office building by Blumer Lehmann

Reception and office building ‘Stammhaus’

The new headquarters of Blumer Lehmann is an unusual timber construction with a free-form staircase as an eye-catcher. The designs for the new office and reception building at the headquarters in Gossau were created by K&L Architekten.

A spacious entrance hall, an event room, a cafeteria with adjoining terrace and 180 workstations are located in the new office and reception building. The centrepiece of the imposing four-storey timber building is the central Free Form staircase, the atrium. The construction was developed in collaboration with the ICD/IKTE institutes at the University of Stuttgart. The curved components were manufactured from the newly developed CLTcurved from Blumer Lehmann in accordance with the planning specifications. They give the staircase the desired curved shape. It winds upwards like a modern tree trunk and connects the four storeys.

The façade design of the timber construction is also striking and appealing. Balconies in front with vertical pilaster strips provide natural sun protection and are supplemented by wooden staple elements where more sun and privacy protection is required. The building is air-conditioned via ventilation and night cooling by means of ventilation flaps and uses activated piles to extract heat from the ground or dissipate it into the ground.
