Modular buildings have been argued to have advantages over traditional buildings, for many different reasons.
Improved Air Quality - A lot of the indoor air quality problems identified in new construction result from elevated moisture levels in the farming materials. Since the modular construction is substantially completed in a factory-controlled setting utilizing dry materials, the prospect of elevated levels of moisture being trapped in the new construction is removed.
Low waste. With the very same plans being constantly built, the producer has records of precisely what amount of substances are necessary for a specified job. Together with the consistency, most builders can design systems that use common lengths of lumber, wallboard, etc.. cut items with maximum efficacy, or have the ability to order exceptional lengths in bulk. While squander from a site-built residence may generally fill several big dumpsters, building of a modular house creates much less waste. According to the UK group WRAP, up to a 90% decrease in substances can be accomplished through the use of modular structure. Materials minimized contain: timber pallets, shrink wrap, cardboard, plasterboard, timber, bricks, concrete, and cement.
Ability to support remote locations. Particularly in countries where potential markets might be located far from industrial centers, such as Australia, there can be a lot higher costs to build a in-house property in a remote area or a place experiencing a construction boom like mining cities. Modular buildings can also be beneficial in providing sanitary and medical facilities where space, time, and money are a problem.
Modular buildings can also contribute to LEED conditions in any kind site-built structure may, and may even provide an edge in the areas of Sustainable websites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Modular construction may also give an advantage in similar categories in the International Green Construction Code.
Quality. Mixing traditional construction methods, quality manufacturing and third party agencies who provide random inspections, testing, and certification services for quality control, commercial modular structures are built in strict compliance with appropriate local, state, and national regulations and codes. On account of the need to transport modules to the final website, each module has to be constructed to independently withstand travel and installation prerequisites. Thus the closing module-to-module assembly of independently durable elements can yield a final product that is stronger than site-built structures. They also provide exceptional moist and cold resistance when compared to timber and other substances, and are immune to both compression decreasing and cold bridging.  Modular units may also be made to fit in with external aesthetics of any existing construction and modular units once constructed can be almost indistinguishable from a site-built structure.
Flexibility. An individual can continually add to your modular building, including creating high rises. When the demands alter, modular buildings may be disassembled and the modules relocated or refurbished for their next usage reducing the demand for raw materials and minimizing the amount of energy expended to make a building to fit the new demand. Essentially, the entire construction could be recycled in some instances.
Environmentally friendly building process. The controlled environment of the mill allows for more precise structure when permitting the extra stuff to be recycled in-house. 
Indoor construction. Assembly is independent of weather, which may boost work efficiency and avoids damaged construction material.
Speed of construction/faster return on investment. Modular construction allows for the construction and the site work to be performed simultaneously. According to some substances, this can decrease the total completion schedule by as much as 50%. This reduces labour, financing and oversight expenses. To save time and money, nearly all engineering and design disciplines are part of the manufacturing procedure. Also unique to modular structure is the capacity to simultaneously construct a building's floors, walls, ceilings, rafters, and roofs. During site-built construction, walls cannot be placed until flooring are in position, and ceilings and rafters cannot be added until walls are erected. On the flip side, with modular construction, walls, floors, ceilings, and rafters are all built at the same time, then brought together in precisely the exact same factory to form a building. This procedure can enable modular construction times of half that of traditional, stick-built structure.
