A new seven-storey building for rentable office space is to be constructed in a gap between buildings in the Karlsruhe Technology Park.
The design envisages an atrium in the centre of the building, which is seen as the heart of the design and creates a pleasant working atmosphere. The atrium provides the primary access to all floors. It connects the individual plots, even across the storeys, via visual connections. In addition, the interior offices are supplied with daylight and air in this way. Small balconies as exits create differentiated spaces. The atrium also offers added value in terms of energy, as it is used as a solar chimney.

The incoming air is channelled into the atrium via an underground duct. This makes an effective contribution to thermal comfort and energy efficiency.
Connecting corridors along the atrium provide access to the two-span office zones and end at the front sides at greened loggias, to which the escape staircases are also connected. Thanks to the design of the supporting structure as a skeleton construction, the layout of the individual offices is variable and independent of the other floors. This enables a room layout that can be adapted to requirements and allows for changes in occupancy. In addition, the layout of the floor plans provides a variety of possible separations for individual tenants within a floor. A floor can be divided into up to four plots.

The planting on the façade breaks up the grid of the side façades and marks the vertical development. In the winter months, the greenery allows the low sun to shine far into the building, while in summer it provides effective sun protection.
The façade (inside and outside) has a modular structure. The prefabrication and elementisation of individual components enables a reduction in construction time and minimises the potential for errors on the building site. The structural shading via louvres, designed differently depending on the sunlight, gives the building a slightly translucent character and is an expression of a paradigm shift in architecture.
