Ability to support remote locations. Particularly in countries where potential markets might be located far from industrial centers, such as Australia, there may be much higher prices to build a site-built house in a remote area or an area experiencing a construction boom like mining cities. Modular buildings can also be beneficial in providing sanitary and medical facilities at which space, time, and money are an issue.
Quality. Combining traditional building techniques, quality manufacturing and third party agencies that offer arbitrary inspections, testing, and certification services for quality control, commercial modular buildings are made in strict accordance with appropriate local, state, and federal rules and regulations. On account of the need to transport modules to the final website, each module has to be constructed to independently withstand traveling and installation requirements. Thus the closing module-to-module assembly of independently durable elements can yield a last product that is stronger than site-built structures. Modular buildings frequently utilize Structural Insulated Panels (SIPs) in construction, which provide a range of advantages over traditional building materials. They also provide exceptional moist and cold resistance when compared to timber and other materials, and are immune to both compression decreasing and cold bridging.  Modular units might also be designed to fit in with outside aesthetics of any existing building and modular units once constructed can be almost indistinguishable from a site-built structure.
Low waste. With the very same plans being continuously built, the producer has records of precisely what quantity of materials are needed for a specified job. Together with the consistency, most builders can design systems which use common lengths of lumber, wallboard, etc.. cut things with maximum efficiency, or be able to order exceptional lengths in bulk. While squander from a site-built dwelling may typically fill several large dumpsters, building of a modular dwelling generates much less waste. According to the UK group WRAP, up to a 90% decrease in substances can be accomplished through using modular construction.
Improved Air Quality - A lot of the indoor air quality problems identified in new construction result from elevated moisture levels in the framing materials. Because the modular construction is substantially finished in a factory-controlled setting using abrasive materials, the prospect of elevated levels of moisture being trapped inside the new construction is removed.
Flexibility. One can add to your modular construction, including creating 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 total amount of energy expended to create a construction to meet the new demand. In essence, the whole building could be recycled in some cases.
Environmentally friendly building procedure. The controlled environment of the factory allows for more accurate construction while allowing the additional materials to be recycled in-house. 
Indoor construction. Construction is different from weather, which may boost work efficiency and averts damaged construction material.
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 costs. To save time and money, the majority of design and engineering disciplines are a part of the production process. Also unique to modular structure is the ability to simultaneously construct a building's floors, ceilings, walls, rafters, and roofs. During site-built construction, walls cannot be placed until flooring are in position, and ceilings and rafters can't be added until walls have been erected. On the other hand, with modular structure, walls, flooring, ceilings, and rafters are all built at precisely the same time, and then brought together at precisely the same mill to form a construction. This process can allow modular construction times of half that of conventional, stick-built construction.
Modular buildings can also contribute to LEED requirements in any category site-built construction may, and may even supply an edge in the fields of Sustainable Sites, Energy and Atmosphere, Materials and Resources, and Indoor Environmental Quality. Modular construction can also provide an edge in similar categories in the International Green Construction Code.
Modular buildings are argued to have advantages over traditional buildings, for a variety of reasons.
