Compared to conventional construction, modular buildings are affordable and cost effective due to their factory construction. Builders and consumers find such buildings much better value than their on-site counterparts. This is one of the reasons for the high demand for modular buildings to meet a wide variety of uses.

Modular buildings provide long-term temporary or permanent facility solutions and uses for schools, credit unions, construction sites, storage facilities, temporary airport terminals, additional classrooms and industrial facilities. Recent innovations have essentially made it difficult to distinguish assembled modular buildings from the ones typically built onsite.

These buildings of often multi-level designs are manufactured, delivered to the site in the individual component parts then constructed into a single building within a short period of time. The modular buildings are assembled off-site in an enclosed facility or factory. Constant material supply and shelter from the weather at the factory eliminates construction delays. Cranes or trucks are used to transport and place the modular buildings at the site. It generally takes several hours or days to instal the buildings.

Well built modular buildings last as long as the site-built counterparts and their value increases over time. The speed of construction, weather-independent indoor construction, favorable supplier prices, remote location services, low waste, and environment friendly process help to make modular building construction at remarkably lower in cost to traditional building methods.
