Excellent: what sets us apart from other prefabricated house companies

Focus on prefabricated house quality

Hanse Haus has stood for prefabricated houses of the highest quality since 1929. That is why we are not afraid of voluntarily subjecting our company to regular inspections by various independent testing institutes. We are a member of renowned quality associations in the construction industry, which carry out officially recognised monitoring and quality control of customer service, production and prefabricated houses. Trust the quality seals and awards and build your certified prefabricated house of the highest quality with us.
