Detached house Ulm
On the slope of the Michelsberg hill in Ulm, the monolithic concrete villa clearly stands out from the built environment. Reduced design with clear lines runs through the entire property: from the joint pattern of the thermal walls to the terrace area with pool and sauna, everything is precisely coordinated. In the interior, too, the constructive joints harmonize with, among other things, LED rails that were recessed into the air-conditioned ceilings during prefabrication. To the north, the building takes up the geometry of the site boundary and allows for optimal integration of the living levels into the existing topography. This also maximizes the southern terrace area. To break up the austerity of the building, a canopy was added to the north to protect the entrance from the elements. In extension of the canopy, a bicycle room separated with black expanded metal forms the structural end.
Inside, the building is designed with open, flowing room transitions. The only fixed point in the levels is the central access staircase with fall protection made of black flat steel. Due to its color contrast to the gray concrete and the acoustic cladding on the underside, the staircase has the effect of a walkable sculpture through all floors. Generous window areas provide a light-flooded ambience. They frame the view of Ulm Cathedral and the Alpine panorama. This image is reinforced by frame extensions, which in some areas also serve as seating areas. The floor-to-ceiling doors, built-in elements and curtains, together with the white-painted floor, form a color counterpoint to the concrete walls.
The precise and homogeneous concrete appearance of the four-story structure is the result of consistent detailing. The deliberate reduction of materials and colors accentuates the clear architecture of the building.
