What is modular construction?
Modular construction is a modern construction method in which complete room modules are prefabricated in the factory and assembled on site in the shortest possible time. This efficient and sustainable form of construction enables high quality, fast construction times and flexible utilisation - ideal for residential buildings, offices, schools or hotels.

What characterises modular construction compared to traditional construction methods
Modular construction is an innovative construction method that sets new standards in efficiency and flexibility. Instead of time-consuming and weather-dependent construction on site, we prefabricate the individual modules using the latest technology in our factory under controlled conditions. These modules are already equipped with everything - walls, ceilings, doors, windows, electrics, floor coverings and sanitary installations. All that remains to be done on site is to assemble and connect them.
This not only saves time, but also offers unrivalled planning and cost security. In addition, the modules can be arranged individually - next to each other, on top of each other or behind each other. This creates customised buildings with flexible use.
Versatile application options - the perfect solution for every requirement
Modular timber construction is incredibly flexible and can be used for a wide variety of purposes:
- Hotels & Boardinghouses High-quality, sustainable accommodation with a feel-good atmosphere up to building class 5.
- Staff flats Comfortable and efficient living space for companies.
- Educational institutions Schools and kindergartens with an ideal room and learning climate realised in a very short time.
- Healthcare Medical practices, care facilities and social buildings that fulfil the highest standards.
- Commercial property & offices Stylish, functional workspaces with a natural flair.
- Private housing with a future From cosy tiny houses to spacious multi-generation homes - our flexible modular timber construction grows with life and the people who live in it. - Customised, sustainable, future-proof.
