Office Building Ulm
The site is located on the edge of an industrial area in Ulm, on an eastern slope with an idyllic view over the adjacent landscape. The existing office complex here was to be extended to the south by a new administration building - independent and yet connected to the existing building. The selected precast concrete structure reinforces the monolithic character of the new building. Above the fully glazed first floor, the cantilevered upper floors are developed into a structure spanning several floors, giving them a floating appearance. The stairwell with elevator and the sanitary facilities form an independent, vertical structure to which the utilization units are connected.
Only a footbridge connects the remote extension with the existing building. As a result, the two buildings do not compete in terms of design and quality. In addition, it would be easier to meet fire protection requirements and the new building could also be operated independently if required. In the future, the north wing of the existing building can be expanded with a similar addition. The building was designed to exceed the requirements of the EnEV and meets the KfW40 standard. The effective insulation of the thermal walls minimizes energy loss through the building envelope and a ventilation system with heat recovery also ensures hygienic air exchange in a particularly energy-efficient manner.
The new building is accessed from the newly constructed parking lot. An open staircase with a covered entrance area leads to the first floor, which contains the foyer, a large meeting room with a kitchenette and the associated sanitary facilities. The meeting room can be divided with a folding wall and its generous glazing with sliding doors establishes the relationship to the landscape and the adjacent open spaces. The stairwell leads in both upper floors through a corridor to the offices of the new building and via a footbridge to the existing building.
Precast concrete allows us to differentiate the building structures not only in their structure, proportion and color, but also in their materiality.
