Flexibility. An individual can continually add to your modular building, such as creating high rises. When the demands alter, modular buildings may be disassembled and the modules relocated or refurbished for their next usage reducing the requirement for raw materials and minimizing the amount of energy expended to create a building to meet the new demand. Essentially, the whole building could be recycled in some instances.
Ability to support remote locations. Especially in countries where potential markets might be found far from industrial facilities, such as Australia, there may be a lot higher prices 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 at which time, space, and funds are an issue.
Low waste. With the very same programs being constantly built, the producer has records of precisely what quantity of substances are needed for a specified job. Together with the consistency, most builders can design systems that use common lengths of lumber, wallboard, etc., cut items with maximum efficacy, or be able to order exceptional spans in bulk. While squander from a site-built residence may generally fill several large dumpsters, construction of a modular house creates much less waste. As stated by the UK group WRAPup to a 90% reduction in materials can be accomplished via the use of modular structure.
Environmentally friendly construction process. The controlled environment of the factory allows for more accurate construction while allowing the extra materials to be recycled in house. 
Indoor construction. Construction is different from weather, which can boost work efficiency and averts damaged building material.
Modular buildings have been argued to have advantages over traditional buildings, for many different factors.
Speed of construction/faster return on investment. Modular construction permits for the construction 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 labor, financing and supervision costs. To save even more time and money, nearly all engineering and design areas are part of the production procedure. During site-built construction, walls cannot be set until floors are set up, and ceilings and rafters cannot be added until walls are erected. On the flip side, with modular structure, walls, floors, ceilings, and rafters are all built at the same time, and then brought together at precisely the exact same mill to form a building. This procedure can enable modular building times of half that of conventional, stick-built construction.
Modular construction may also give an edge in similar categories from the International Green Construction Code.
Improved Air Quality - Many of the indoor air quality problems 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 structure is removed.
Quality. Combining traditional building methods, quality manufacturing and third-party agencies who offer arbitrary inspections, testing, and certification solutions for quality management, commercial modular buildings are built in strict compliance with appropriate local, state, and federal regulations and codes. On account of the requirement to transport modules to the final site, each module must be built to independently withstand travel and installation requirements. Thus the closing module-to-module assembly of independently durable elements can yield a final 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. SIPs panels are a light yet durable combination of board and either closed-cell polyurethane (PU) or expanded polystyrene (EPS) insulation. They also offer exceptional moist and cold immunity when compared to timber and other substances, and are immune to both compression decreasing and cold bridging.  Modular units might also be designed to match in with external aesthetics of any present construction and modular units after constructed can be virtually indistinguishable from a site-built structure.
