Product Description

Have a real estate project? We have the team of designers and manufacturers who will make it happen. Enjoy a faster return on your investment by opting for modular construction.

The modular container unit is designed as a light solid construction consisting of floor and roof frames and corner profiles. The system enables compounding of individual containers in longitudinal and transverse directions without limits. It also enables compounding of containers in 2 floors in height (ground floor + first floor), or in 3 floors in height for warehousing of these containers (ground floor + 2 floor). The container houses are made of light insulation panels and offer pleasant climate in the interior due to their building and physical properties.
