- 83 apartments – SolarArchitect Rolf Disch
In Schallstadt, an idyllic village five kilometers south of Freiburg/Germany, the “PlusEnergy climate houses” are being built on a plot of about 4,500 m².

- Project
In Karlsruhe/Germany, Vollack is realizing the new working environment for the IT service provider generic.de in an advanced wood hybrid construction. The building is energetically optimized and will be constructed in passive house standard. The new two-, partly three-story building with a gross floor area of around 3,300 square meters will provide 110 workplaces in the future. The corporate principle ‘Clean Code Development’, according to which generic.de AG develops its sustainable software, is not only reflected in the slogan, but also in the construction method: Here, as in software development, the main focus is fully on sustainability. With its significant architecture in the form of a bar code, which mirrors the signet in the generic.de logo, the building deliberately turns away from the orthogonal and thus creates a connection with the surrounding residential and commercial development as well as an adjacent sports field. - Concept, planning, construction:
