Ability to service remote locations. Especially in countries in which potential markets might be located far from industrial centers, such as Australia, there may be a lot higher costs to construct a in-house property in a distant area or an area experiencing a building boom like mining cities. Modular buildings are also beneficial in providing medical and sanitary facilities at which time, space, and funds are an issue.
Flexibility. An individual can continually add to your modular building, including producing high rises. When the needs alter, modular buildings can be disassembled and the modules emptied or refurbished to their next usage reducing the requirement for raw materials and minimizing the amount of energy expended to create a building to fit the new need. Essentially, the whole construction can be recycled in some cases.
Improved Air Quality - A lot of the indoor air quality issues identified in new construction result from elevated moisture levels in the farming materials. Since the modular construction is substantially finished in a factory-controlled setting using abrasive materials, the potential for high levels of moisture being trapped in the new structure is eliminated.
Indoor construction. Assembly is different from weather, which can boost work efficiency and avoids damaged building material.
Modular construction can also give an edge in similar classes in the International Green Construction Code.
Low waste. With the very same plans being constantly built, the manufacturer has records of precisely what quantity of materials are necessary for a specified job. Together with the consistency, most builders can design systems which use common lengths of lumber, wallboard, etc., cut items with maximum efficacy, or be able to order special spans in bulk. While waste from a site-built residence may generally fill several large dumpsters, building of a modular house creates much less waste. As stated by the UK group WRAP, up to a 90% reduction in substances can be achieved through the use of modular construction. Materials minimized contain: timber pallets, shrink wrap, cardboard, plasterboard, timber, concrete, bricks, and cement.
Quality. Combining traditional building techniques, quality manufacturing and third party agencies who provide arbitrary inspections, testing, and certification services for quality control, commercial modular structures are made in strict accordance with appropriate local, state, and national rules and regulations. On account of the requirement to transport modules to the final website, each module must be constructed to independently withstand traveling and setup prerequisites. Thus the final module-to-module assembly of independently durable components can yield a last product that is more durable than site-built structures. SIPs panels are a mild yet durable combination of board and either closed-cell polyurethane (PU) or expanded polystyrene (EPS) insulation. They also offer exceptional moist and cold resistance when compared to timber and other materials, and are resistant to both compression shrinking and cold bridging.  Modular units might also be designed to fit in with outside aesthetics of any present construction and modular units after constructed can be almost indistinguishable from a site-built structure.
Environmentally friendly construction procedure. The controlled environment of the factory allows for more precise structure while allowing the extra materials to be recycled in house. 
Speed of construction/faster return on investment. Modular construction permits for the building and the site work to be performed simultaneously. According to some materials, this can decrease the overall completion schedule by up to 50%. This also reduces labour, financing and supervision costs. To save time and money, nearly all design and engineering areas are part of the production process. Also unique to modular construction is the capacity to simultaneously construct a building's floors, walls, ceilings, rafters, and roofs. During site-built structure, walls can't be placed until flooring are in position, and ceilings and rafters can't be added till walls are erected. On the flip side, with modular construction, walls, flooring, ceilings, and rafters are all built at precisely the same time, then brought together at precisely the exact same factory to form a construction. This procedure can allow modular construction times of half an traditional, stick-built construction.
Modular buildings have been argued to have advantages over traditional buildings, for many different factors.
