REM is a medium-sized enterprise that plays an important role in the production of prefabricated modular buildings and living containers in Slovenia as well as in Europe and elsewhere in the world. We specialize in the production of modular units with an emphasis on sanitary and living containers, while in recent years, by forming our own development team and construction department, we are focusing more on designing, manufacture and assembly of high-performance prefabricated modular buildings and engineering.

We constantly expand our product range and services, and improve the quality of our products. Particular attention is paid to the appearance of our finished products.
