Roof Garden Dresden Small house garden on the roof of an underground car park

The small house garden is designed as an intensive green roof on the roof of an underground car park. Historic sandstones and old paving combined with modern Corten steel - the mixture of modern construction methods and historic existing materials characterises the architecture of the inner-city area and is also reflected in the design of this roof garden.

At certain points, statically particularly load-bearing points (supports in the basement) were used to insert raised beds with Corten steel edging. Here, it was also possible to plant trees, the growth of which is also statically calculated. An automatic irrigation system with connection to a sufficiently large rainwater cistern ensures the preservation of the year-round attractive planting with early bloomers, perennials, herbs and shrubs.

Almost the entire roof areas of the surrounding residential complex drain into the cistern, instead of into the municipal sewer lines. Excess water seeps into the sandy, gravelly subsoil of the property. And from the vegetated areas, a good portion of the water also evaporates back into the air. In the densely built-up inner city, a small plot of land thus makes a major contribution to improving the urban climate by returning rainwater to the water cycle - as plant food to the greenery, as water vapour to the air and as seepage water to the subsoil for groundwater recharge.
