Quality. Mixing traditional construction techniques, quality manufacturing and third-party agencies that offer random inspections, testing, and certification solutions for quality control, commercial modular buildings are made in strict accordance with appropriate local, state, and national regulations and codes. Due to the need to transport modules to the final site, each module has to be constructed to independently withstand travel and setup requirements. Thus the final module-to-module assembly of independently durable elements can yield a last product which is stronger than site-built structures. Modular buildings frequently use Structural Insulated Panels (SIPs) in construction, which offer a range of benefits over traditional construction materials. They're air-tight, and as such provide exceptional thermal performance. They also provide superior damp and cold immunity when compared to wood and other substances, and are immune to both compression decreasing and cold bridging.  Modular units might also be made to fit in with external aesthetics of any present construction and modular units after constructed can be virtually indistinguishable from a site-built structure.
Ability to support remote locations. Particularly in countries in which potential markets may be located far from industrial centers, such as Australia, there can be a lot higher prices to construct a in-house property in a distant area or an area experiencing a construction boom like mining towns. Modular buildings are also beneficial in providing medical and sanitary facilities where space, time, and money are an issue.
Environmentally friendly building process. The controlled environment of the factory allows for more precise structure when allowing the extra stuff to be recycled in-house. 
Modular construction can also provide an edge in similar categories in the International Green Construction Code.
Indoor construction. Assembly is independent of weather, which can boost work efficiency and averts damaged construction material.
Improved Air Quality - A lot of the indoor air quality issues identified in new construction result from high moisture levels in the framing materials. Since the modular structure is substantially completed in a factory-controlled setting utilizing abrasive materials, the prospect of high levels of moisture being trapped inside the new construction is eliminated.
Modular buildings have been argued to have benefits over traditional buildings, for a variety of factors.
Flexibility. An individual can add to your modular construction, including producing high rises. When the demands alter, modular buildings may be disassembled and the modules emptied or refurbished to their next use reducing the requirement for raw materials and minimizing the total amount of energy expended to make a construction to fit the new need. Essentially, the whole construction could be recycled in some cases.
Low waste. With the very same programs being continuously built, the producer has records of precisely what quantity of substances are necessary for a given job. With the consistency, builders can design systems that use common lengths of timber, wallboard, etc.. cut items with maximum efficacy, or have the ability to order exceptional spans in bulk. While waste from a site-built dwelling may typically fill several large dumpsters, construction of a modular dwelling generates much less waste. As stated by the UK group WRAPup to a 90% decrease in materials can be achieved through the use of modular construction. Materials minimized contain: timber pallets, shrink wrap, cardboard, plasterboard, wood, bricks, concrete, and cement.
Modular construction permits for the building and the site work to be performed concurrently. According to some substances, this can decrease the total completion schedule by as much as 50%. This reduces labour, financing and oversight costs. To save even more time and money, nearly all engineering and design disciplines are part of the manufacturing process. During site-built structure, walls can't be set until floors are set up, and ceilings and rafters can't be added till walls have been erected. On the flip side, with modular construction, walls, flooring, ceilings, and rafters are all constructed at the exact same time, then brought together at the exact same factory to form a building. This process can enable modular construction times of half an traditional, stick-built construction.
