The striking building with eight residential units on Klaffensteinstrasse in the German Böblingen is both aesthetically and ecologically a lighthouse project. As the first apartment building in Germany to be awarded the energy efficiency class 40plus, builder and planner Ralf Sklarski succeeded in creating a sustainable building.

However, the house is not only to be talked about because of its forward-looking construction, but also because of its unique facades. On the south side, perforated elements and parapets by Bruag emphasize the extraordinary design of the house. On the north side, a banner protruding from all floors, which depicts the property as an untouched landscape, attracts the views.

“Time and again, people stop in amazement or deliberately take a walk along the Klaffensteinstrasse,” Ralf Sklarski says with a laugh. The surprise effect was great, especially after the removal of the scaffolding.

“Until then, no one could have imagined what the plot of land, which had previously been divided into many small plots, would look like with a single building. We are of course pleased that the echo is so positive,” says the planner and builder.

The spectrum of Ralf Sklarski Bauunternehmung GmbH in Böblingen, which now employs more than 50 people, is just as versatile as the successful new building. Whether it is building, horticulture, landscaping, property management or commissioned work for municipal facilities and urban buildings: The family business, founded in 1973, sees itself not only as a construction entrepreneur, but also as a contractor.
