It only takes one day to assemble the prefabricated, solid room modules at the building site. You are no longer dependent on the workers’ form of the day and can count on the highest quality standards. After all, building a house probably is one of the biggest investments of your life …

All production steps are executed and supervised according to certified quality processes. Our housing technology packages are certified by independent TÜV energy experts.
