The architectural conception
The office is directly situated at the existing pond. It is a lumber-glass-construction with a solid sunlit memory-wall inside. A glazed south zone serves the opening up, the communication and the combination to the water, weather and the sun. The following range is exposed only diffusely; orientate direct light from the north and about window shades’ controllable light from the south and offers thus optimal conditions for the office operation.
The access is carried out at the western narrow dimension, direct at the water. Across the reception, through the solar memory-wall, one reaches at the south side of the building, which in the customer range as consultation zone serves and which is organized on two floors with a supplementary terrace over the water.
Internal communication centre is a sort of island in the centre of the ground floor with a snack-bar. A weather-protected connection to the workshop and the store is also carried out from here. The factory is situated-and works-parallel to the office with which it together forms an inner “office-yard”, in which the visitors could not look in.
The character of the south facade is the hugh vitrification and the floating crossover between communication-inside and experience area-outside. The glass wall is interrupted by a blue violet, reflecting collector area in the score range.
A footbridge over the water makes connection to the water and subsequently to the walk over the expanse of water. The office building is placed so that the existing old swimming pond can be remain unchanged and seems visual as a part of the complete expanse of water. The terrace at the old pond is shadowed and for consultations in the midsummer particularly valuable.

Energetic conception
High insulated outside walls and best vitrifications guarantee less wastages. The input air is supplied over ground canals, brought in (permanently optimal air quality) and led away over a warmth recycling plant. The supply air is one blown to the offices and continued to the winter garden and siphoned over the sanitary rooms from there.
The winter sun is taken about the south glazing and stored in the building mass or transferred to the input air over the ventilation equipment (heat exchanger) passively.
About hot-water collectors in the façade the hot-water need for workshops and office is covered. This collector plant and the building became so proportioned that the remains warmth need corresponds to the energy salary of the biomass of the wood scraps of the market garden operation exactly. This rest warmth need is covered by a biomass plant.
The summarily overheat protection is guaranteed by the high insulation, the complete shadowed south glazing, the cooling of the input air in the ground and also by the automatically night-ventilation.
Additionally cooling can be led in by a “concrete-core-activation”, that means, that the water of the well is carried in ducts through the cement-mass.
Photovoltaic elements are optionally possible.

Water conception
The existing pond shows the state one grown for long time. The large expanse of water demonstrates the large swimming range as well as different concepts of planting between the footbridges. An experience range developed about wood platforms consists in the eastern range.
A sewage plant for complete dirt water cleaning is situated in the south eastern range of the property.
The waste waters of the roof lead in seeping areas whose planted margin design is tied into the clearance concept at the property.
