Check out our newest modular condo construction project! Modular buildings are prefabricated buildings that consist of repeated sections called modules. "Modular" is a construction method that involves constructing sections away from the building site, then delivering them to the intended site. Installation of the prefabricated sections is completed on site. Prefabricated sections are placed using a crane. The modules can be placed side-by-side, end-to-end, or stacked, allowing a variety of configurations and styles.
