The goal was to create an ambitious architecture with means as simple as possible, such as bonded wooden construction. The task consisted of the erection of a new commercial building for the company Tobias Grau, which at the time numbered 30 employees. The floor plan comprises a warehouse for prefabricated parts with dedicated areas for final assembly, delivery and shipping, as well as an office section for the commercial and design departments. The building has been extended in a second phase, whereby this had been foreseen in the origional planning with regard to design, work flow, and cost aspects. The design presents a completely novel building concept. The first construction phase consists of an elongated, oval edifice.

A second, identical shape has been executed as the extension and connected to the first building by a two-storey, almost square edifice. The construction consists of bonded wood beams spanning over 20 meters, which were erected at a distance of 5 meters and which support the external aluminium skin made of Alucobond panels.
An inserted concrete table in the first building results in two-storey use and at the same time serves as reinforcement. This concrete table is formed as a soffit in circular domical form with a camber of 10 cm and stands on filigree concrete supports. In the upper floor the supporting structure is completed by wooden socketed columns.
The additional building also in bonded wood construction, is a large entirely column-free hall.
