Modular buildings and modular houses/homes are sectional prefabricated buildings, or houses, that consist of multiple sections called modules. "Modular" is a method of construction differing from other methods (e.g. "stick-built" and other methods such as off-site construction). The modules are six sided boxes constructed in an exterior (sometimes, remote) facility, then delivered to their intended site of use. Using a crane, the modules are set onto the building's foundation and joined together to make a single building. The modules can be placed side-by-side, end-to-end, or stacked, allowing a wide variety of configurations and styles in the building layout.

Modular buildings, also called prefabricated buildings, differ from mobile homes, which are also called manufactured homes, in two ways. First, modular homes do not have axles or a frame, meaning that they are typically transported to their site by means of flat-bed trucks. Secondly, modular buildings must conform to all local building codes for their proposed use, while mobile homes, made in the United States, are required to conform to federal codes governed by HUD (U.S. Department of Housing and Urban Development).^[1] There are some residential modular buildings that are built on a steel frame (referred to as on-frame modular) that do meet local building codes and are considered modular homes, rather than mobile homes.

Insight into the modular house


Wide application for Containerized Modular House Solution:
Modular Houses may be used for long-term, temporary or permanent facilities, such as construction camps, schools and classrooms, civilian and military housing, and industrial facilities.^[2] Modular buildings are used in remote and rural areas where conventional construction may not be reasonable or possible.Other uses have included churches, health care facilities, sales and retail offices, fast food restaurants and cruise ship construction. They can also be used in areas that have weather concerns, such as hurricanes.

Construction process for modular house
Modular components are typically constructed indoors on assembly lines. Modules' construction may take as little as ten days but more often one to three months. Completed modules are transported to the building site and assembled by a crane.^[4] Placement of the modules may take from several hours to several days.

Manufacturing considerations

Modular buildings are argued to have advantages over conventional buildings, for a variety of reasons.

• Speed of construction/faster return on investment. Modular construction allows for the building and the site work to be completed simultaneously. According to some materials, this can reduce the overall completion schedule by as much as 50%.
• Indoor construction. Assembly is independent of weather, which can increase work efficiency and avoids damaged building material.
• Ability to service remote locations. Particularly in countries in which potential markets may be located far from industrial centers, such as Australia, there can be much higher costs to build a site-built house in a remote area or an area experiencing a construction boom such as mining towns.^{[citation needed]}
• Low waste. With the same plans being constantly built, the manufacturer has records of exactly what quantity of materials are needed for a given job. While waste from a site-built dwelling may typically fill several large dumpsters, construction of a modular dwelling generates much less waste.
• Environmentally friendly construction process. Modular construction reduces waste and site disturbance compared to site-built structures.^{[citation needed]}
• Flexibility. One can continually add to a modular building, including creating high rises.^[6]
