The two-storey, rectangular solitaire is located in the Amsterdam district of Osdorf and blends in with an appropriate distance between the trees and the surrounding buildings. The ground floor, which is glazed on all sides, blurs the transition between inside and outside, making the park and trees a flowing part of the interior that can be experienced as a "public living room".
In contrast, the upper floor is solid without openings. Behind the enclosed shell is the multifunctional room, which is completely white and is only lit by two large skylights.
The combination of both types of space – open and closed space – determines the appearance and character of the building. It is directly legible from the outside and dominates the façade design. Inside, the contrast between the two room constellations also determines perception and surprises, as the fully closed room appears much brighter than the fully open one. In this way, the simple stacking of two room concepts, which are diametrically opposed, creates a building with completely different spatial concepts.
Construction
The construction, which was erected as a result of a very low construction budget as a cost-effective steel structure with sand-lime brick infills, is based on the surrounding industrial facilities. The all-glass façades are supported at the top and bottom by steel profiles and measure up to 5m. The structurally glued glass doors were specially designed for the project.
The special thing about "De Hood" is the external insulation on the upper floor. The sand-lime brick walls were insulated with a polyurethane spray system, which is normally used in petroleum tanks and pigsties. The initially liquid plastic foams up and hardens completely. The resulting coarse and rough surface had to be provided with a UV protection coating. The polyurethane foam corresponds to the thermal conductivity group (WLG) 022 with an insulation thickness of 12 cm. The false ceilings and the roof are constructed as reinforced concrete hollow ceilings and reinforced concrete element ceilings. The flat roof, which was covered with slope insulation (thickness 14 to 22 cm) (non-combustible, pressure-resistant mineral wool WLG 040), was covered with a gravel fill as wind suction protection.
All technical installations were integrated into the walls and the floor floor. This made it possible to dispense with suspended ceilings, which allows for a higher floor height.
The interior is characterised by a similar economic and design approach. The concrete floor, which was not quite smooth, was only coated with polyurethane, and the ceiling was provided with coarse acoustic spray plaster.
