Improved Air Quality - Many of the indoor air quality problems identified in new construction result from high moisture levels in 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 in the new structure is removed.
Modular buildings may also contribute to LEED conditions in almost any category site-built structure can, and can even supply an edge in the areas of Sustainable websites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Modular construction may also give an edge in similar classes from the International Green Construction Code.
Ability to support remote locations. Particularly in countries in which potential markets might be located far from industrial facilities, such as Australia, there may be a lot higher costs to build a site-built house in a distant area or an area experiencing a building boom such as mining cities. Modular buildings are also beneficial in providing medical and sanitary facilities where space, time, and money are an issue.
Quality. Combining traditional building methods, quality manufacturing and third party agencies who offer random inspections, testing, and certification services for quality management, commercial modular structures are built in strict accordance with appropriate local, state, and federal rules and regulations. Due to the need to transport modules to the last site, each module has to be constructed to independently withstand travel and installation requirements. Thus the final module-to-module meeting of independently durable components can yield a last product that is stronger than site-built structures. SIPs panels are a light yet durable mix of panel board and either closed-cell polyurethane (PU) or expanded polystyrene (EPS) insulation. They're air-tight, and as such provide excellent thermal performance. They also provide superior moist and cold immunity when compared to timber and other substances, and are resistant to both compression shrinking and cold bridging.  Modular units might also be designed to match in with external aesthetics of any present building and modular units once constructed can be almost indistinguishable from a site-built structure.
Low waste. With the same plans being constantly built, the producer has records of precisely what amount of substances are needed for a specified job. Together with the consistency, most builders can design systems that use common lengths of timber, wallboard, etc.. cut things with maximum efficacy, or have the ability to order exceptional spans in bulk. While squander from a site-built residence may generally fill several big dumpsters, building of a modular dwelling generates much less waste. According to the UK group WRAP, up to a 90% reduction in materials can be achieved through the use of modular structure. Materials minimized include: timber pallets, shrink wrap, cardboard, plasterboard, timber, bricks, concrete, and cement.
Indoor construction. Assembly is different from weather, which may boost work efficiency and averts damaged building material.
Modular buildings have been argued to have advantages over conventional buildings, for a variety of reasons.
Environmentally friendly construction process. Modular construction reduces waste and site disturbance in contrast to site-built structures. The controlled environment of the factory allows for more precise structure while permitting the extra stuff to be recycled in house. 
Modular construction allows for the construction and the site work to be completed simultaneously. According to some substances, this can decrease the overall completion schedule by as much as 50%. This also reduces labor, financing and oversight expenses. To save even more time and money, the majority of engineering and design disciplines are a part of the production procedure. During site-built structure, walls can't be placed until flooring are set up, and ceilings and rafters can't be added till walls have been erected. On the other hand, with modular construction, walls, floors, ceilings, and rafters are all constructed at precisely the exact same time, and then brought together at precisely the same factory to form a building. This process can enable modular building times of half an traditional, stick-built construction.
Flexibility. An individual can add to your modular building, including producing high rises. When the needs change, modular buildings may be disassembled and the modules relocated or refurbished to their next usage reducing the demand for raw materials and minimizing the amount of energy expended to make a construction to fit the new need. Essentially, the whole construction could be recycled in some cases.
