Indoor construction. Assembly is different from weather, which may increase work efficiency and averts damaged construction material.
Flexibility. One can continually add to your modular construction, such as creating high rises. When the demands change, modular buildings can be disassembled and the modules emptied or refurbished to their next use reducing the demand for raw materials and minimizing the total amount of energy expended to make a construction to meet the new demand. In essence, the whole construction can be recycled in some cases.
Speed of construction/faster return on investment. Modular construction allows for the building and the site work to be completed simultaneously. According to some substances, this can decrease the overall completion schedule by up to 50%. This reduces labour, financing and oversight costs. To save even more time and money, the majority of engineering and design disciplines are a part of the production procedure. Also unique to modular construction is the capacity to simultaneously construct a building's floors, walls, ceilings, rafters, and roofs. During site-built structure, walls cannot 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 structure, walls, flooring, ceilings, and rafters are all built at precisely the exact same time, and then brought together at the exact same mill to form a construction. This process can allow modular construction times of half that of traditional, stick-built construction.
Improved Air Quality - A lot of the indoor air quality issues identified in new structure result from high humidity levels from the framing materials. Since the modular structure is substantially completed in a factory-controlled setting using abrasive materials, the potential for high levels of moisture being trapped in the new structure is removed.
Modular buildings may likewise contribute to LEED conditions in almost any kind site-built structure may, and can even supply an advantage in the areas of Sustainable websites, 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.
Quality. Mixing traditional construction techniques, quality manufacturing and third party agencies that offer random inspections, testing, and certification solutions for quality control, commercial modular structures are made in strict accordance with appropriate local, state, and national regulations and codes. Due to the need to transport modules to the final website, each module has to be constructed to independently withstand travel and installation requirements. Thus the final module-to-module assembly of independently durable elements can yield a last product which is more durable than site-built structures. They also offer exceptional moist and cold resistance when compared to wood and other substances, and are immune to both compression shrinking and cold bridging.  Modular units might also be made to fit in with outside aesthetics of any present building and modular units once constructed can be almost indistinguishable from a site-built construction.
Environmentally friendly construction procedure. Modular construction reduces waste and site disturbance compared to site-built structures. The controlled environment of the factory allows for more accurate construction while permitting the extra stuff to be recycled in house. 
Ability to service remote locations. Especially in countries in which prospective markets might be found far from industrial facilities, such as Australia, there can be a lot higher costs to build a site-built house in a distant area or an area experiencing a construction boom like mining cities. Modular buildings are also beneficial in providing sanitary and medical facilities where time, space, and funds are an issue.
Low waste. With the very same programs being continuously built, the manufacturer has records of precisely what quantity of materials are necessary for a specified job. Together with the consistency, most builders can design systems which use common lengths of lumber, wallboard, etc.. cut items with maximum efficacy, or be able to order exceptional lengths in bulk. While squander from a site-built residence may generally fill several large dumpsters, building of a modular house creates much less waste. As stated by the UK group WRAPup to a 90% decrease in materials can be achieved via the use of modular structure.
Modular buildings have been argued to have advantages over conventional buildings, for a variety of factors.
