Light-coloured wood, red brick and green courtyards

Diversity, flexibility and neighbourliness are the guiding principles of the residential project on the site of the US Army Hospital in Heidelberg. Diversity through a variety of future residents, flexibility through variable uses of the basic structure and neighbourliness through social interaction within the two building plots. This is made possible, for example, by a front courtyard in front of the three-point buildings or a semi-public inner courtyard in the separate building block.

The timber hybrid construction made of prefabricated elements enables the building project to be realised quickly, cost-effectively and in a way that conserves resources. Differently designed timber façades give the buildings an individual character and set them apart from the surrounding blocks of the US hospital flats.

Blocks made from prefabricated timber elements

We have designed the two building plots very differently. On the first plot, two L-shaped blocks of three houses are grouped around a green inner courtyard. The spatial concept offers high-quality floor plan typologies and flexible structures ranging from maisonette flats with a directly connected underground car park to conceptual living and retirement flats. On the ground floor, studio flats, a neighbourhood café, co-working spaces and a residents' meeting place create attractive meeting places.

Massive point houses with red brick façades

Three rectangular point blocks with red brick façades are embedded in the green strip on the northern periphery of the neighbourhood on the second construction site. This forms a buffer zone between the new residential neighbourhood and the existing buildings to the north. The neighbourhood park to the south offers an unobstructed view and optimal lighting. The point blocks will be built in solid construction. The red brick façades with bay windows and generously projecting balconies create a striking address. The shared basement of the three buildings houses storage and rubbish rooms as well as the bicycle cellar.
