In the capital, affordable living space like the two three- and four-storey buildings on Sterndamm in south-east Berlin is just what is needed. In addition to the moderate rents, the green refuge between the buildings with a small playground and individual facilities for the residential community for dementia patients is also appealing. Furthermore, an attractive eco-paving solution was also found for paving the parking area, which was initially to be sealed for water protection reasons. The GDM.DRAIN stone proWater surface system with pollutant retention in a rustic stone design was used, which is compatible with the ensemble protection in the neighborhood.
