The entire workshop area is designed to be as flexible as possible. The necessary cores functions of the workshop are located on the peripheral areas, so as not to impede on further development. A connection to the new cafeteria, administration and seminar building is from a mezzanine level via a bridge, allowing for all the zones to be connected, while maintaining independence from each other. The production building is situated on the east side of the village square, with its own delivery zone. The existing workshop and cafeteria buildings are to be reused as generic functional working areas.

The workshop building is built using a mixture construction method, both timber and concreate. A large concreate footprint base layer is created.  From this level, concreate pillars rise up to create an additional level, with a concreate ceiling.  The additional space above the concreate footprint is double height, and with a wooden ceiling.  The second floor is built entirely in wood, as well as the cafeteria administration building. Over the cafeteria area there is a concrete ceiling, the remaining two floors are designed using timber construction. Natural wood is the main material both outdoors and indoors. The colour accentuation of individual areas is very discreet.

The hybrid timber construction is a good basis for achieving the goals of energy-efficient construction. Particular attention is paid to the use materials that have no negative health impacts on the buildings users. All material decisions are subject to these criteria. The uses of durable materials in the building structure, allows flexibility, and guarantees low life-cycle costs. Likewise, all technical equipment and cabling remain accessible, to ensure ease of use when there are slight changes or maintenance required. Compact structures in conjunction with optimised building envelopes enable a reasonable energy concept; a passive house quality.

The compact design of the building ensures minimised energy consumption with an optimised building envelope and high levels of daylight utilisation. To generate heat, the wood remnants are salvaged and used. For the hot water preparation, the waste heat of the compressed air generation is used. The heat transfer in the production and storage areas is carried out by radiant ceiling panels. The shed roofs serve, on the one hand, as a ventilation option and on the other, as a mounting surface for the photovoltaic modules. The new administration building is equipped with a ventilation system with heat recovery in the canteen and in the seminar rooms. By using a geothermal heat exchanger, the supply air is preconditioned.
