Choose Your Modular House Design
Select a ready-made concept or use it as a base for your custom modular house.
As part of a collaboration with Rosenheim Technical University, a curated collection of 12 architectural designs for contemporary living modules was created.
The concepts were developed as part of a student design competition and showcase a diverse range of spatial ideas – from precisely designed micro homes to compact, highly functional living solutions.
Even though we now develop our own residential modules exclusively, the conceptual depth of this project provides valuable inspiration for our design approach and our commitment to clear, high-quality architecture in modular construction.
Modern living space made from wooden modules: energy-efficient, flexible and ready to move into in no time.
