Quality. Mixing traditional construction methods, quality manufacturing and third-party agencies who offer arbitrary inspections, testing, and certification solutions for quality control, commercial modular buildings are made in strict compliance 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 travel and installation prerequisites. Thus the final module-to-module assembly of independently durable components can yield a final product which is stronger than site-built structures. Modular buildings frequently utilize Structural Insulated Panels (SIPs) in construction, which offer a range of benefits over traditional construction materials. They're air-tight, and as such provide excellent thermal performance. They also provide superior moist and cold resistance when compared to timber and other substances, and are resistant 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 after constructed can be almost indistinguishable from a site-built construction.
Ability to service remote locations. Particularly in countries in which prospective markets may 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 a place experiencing a building boom like mining towns. Modular buildings are also beneficial in providing medical and sanitary facilities where time, space, and funds are an issue.
Indoor construction. Construction is independent of weather, which may increase work efficiency and avoids damaged building material.
Environmentally friendly construction process. The controlled environment of the factory allows for more accurate construction when allowing the extra stuff to be recycled in-house. 
Low waste. With the very same programs being continuously built, the manufacturer has records of precisely what quantity of materials are needed for a given job. Together with the consistency, builders can design systems which use common lengths of timber, wallboard, etc., cut things with maximum efficacy, or be able to order exceptional lengths in bulk. While waste from a site-built residence may generally fill several large dumpsters, construction of a modular house creates much less waste. According to the UK group WRAP, up to a 90% decrease in materials can be achieved via the use of modular construction.
Modular construction allows for the building and the site work to be completed concurrently. According to some substances, this can reduce the overall completion schedule by as much as 50%. This reduces labour, financing and oversight expenses. To save even more time and money, nearly all design and engineering areas are a part of the production procedure. Also unique to modular construction is the ability to simultaneously construct a building's floors, walls, ceilings, rafters, and roofs. During site-built structure, walls can't be placed until flooring are set up, and ceilings and rafters can't be added until walls have been erected. On the flip side, with modular construction, walls, flooring, ceilings, and rafters are all built at the same time, and then brought together in the exact same mill to form a building. This procedure can enable modular construction times of half that of conventional, stick-built structure.
Flexibility. An individual can continually add to a modular construction, including producing high rises. When the needs 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 need. Essentially, the whole building could be recycled in some instances.
Modular buildings have been argued to have benefits over traditional buildings, for a variety of reasons.
Improved Air Quality - A lot of the indoor air quality problems identified in new structure result from elevated humidity levels from the farming materials. Since the modular structure is substantially finished in a factory-controlled setting utilizing abrasive materials, the potential for high levels of moisture being trapped inside the new construction is eliminated.
Modular buildings may also contribute to LEED requirements in almost any category site-built structure may, and may even supply an advantage in the areas of Sustainable Sites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Modular construction may also provide an advantage in similar classes in the International Green Construction Code.
