In the online directory, a selection of existing buildings per country can be seen, including some construction information such as year of completion, location, exact construction method, size and participating construction companies. A short description of the houses shows whether it is a new building, an extension or renovation and how the building is used. In addition to single-family and multi-family houses, there are numerous public buildings such as schools, kindergartens, office buildings, cafes and seminar centers.
