The Polish firm Dom Architektow -- founded by the married couple Walenty Durka and Emilia Durka-Zielińskaha – has developed a timber system of modular dwellings. The DA House combines simplicity and prefabricated construction with recyclable and ecological certified materials. Keeping carbon footprint in mind, the structure and the partitions are executed with wood and materials derived from it, in transportable modules. Its mobile foundations allow adaptation to the site’s irregularities.
