This document compares different types of modular bunk houses and shelters made by Evercool, including lift-and-shift/knockdown, dismantle/detachable, and conventional designs. The lift-and-shift modular shelters can be quickly installed and relocated without foundations, while dismantle shelters require time and foundations but are cheaper for longer-term use. Conventional designs are more expensive to transport and install due to their weight. Evercool also produces other modular composite structures like offices, cabins, workmen colonies, toilets, security booths, and classrooms made of materials that are maintenance-free, termite resistant, and customizable.
