A Modular House is divided into individual modules manufactured in a factory, then transported to the construction site for lifting, connection, and final work. Depending on the design, factory production may include the main structure, building envelope, MEP systems, and part of the interior finishing.
Production starts with architectural design and engineering. Before manufacturing begins, the layout, structural system, doors and windows, MEP systems, interior configuration, and connections between modules must be defined.
Because the modules must be transported and lifted, their dimensions, weight, transportation route, and site installation conditions should also be considered during the design stage.
The factory first manufactures and assembles the main structure of each module. For a steel-framed modular house, the steel frame and its connections are typically completed before the walls, floor, and roof systems are installed.
The modules also need appropriate preparation for transportation and lifting according to the project requirements.
After the main structure is completed, workers install wall systems, roofing, windows, waterproofing, and insulation materials.
These components form the building envelope and are selected according to the design requirements for insulation, weather protection, and other performance considerations.
The next stage may include electrical, plumbing, and HVAC installation. Depending on the product design and project requirements, some Modular House units can also have interior work completed in the factory, such as flooring, wall finishes, ceilings, and bathroom installation.
Quality checks can be performed throughout the manufacturing process. Structural dimensions and connections can be checked after frame assembly, while electrical and plumbing systems can be inspected before walls are closed.
Factory production also provides a controlled environment where different construction processes can follow defined procedures.
Before shipment, completed modules undergo final checks and are prepared for transportation. Modules that are transported as complete units also need suitable protection and consideration for lifting, securing, and site installation.
Factory production does not mean that the entire building project is finished. After transportation to the site, the modules generally need to be lifted and positioned on the prepared foundation.
Workers may then complete structural connections between modules, utility interfaces, sealing, and other site-specific finishing work.
For projects using steel-framed modules with integrated building systems, reviewing a suitable modular house solution can help determine the appropriate configuration based on the project requirements.
A modular house can be divided into standardized manufacturing stages, allowing structural, envelope, MEP, and interior work to be organized in a factory environment. Meanwhile, site preparation and foundation work can proceed alongside factory production.
However, the overall project schedule depends on more than factory manufacturing. Design approval, material supply, transportation, foundation work, and site installation can all affect the final timeline.
Not always. The level of factory completion varies by product and project. Some modules can include substantial structural, MEP, and interior work, while other work is completed on site.
Typical work includes lifting and positioning the modules, making structural connections, connecting utilities, and completing necessary site finishing.
The overall schedule can be affected by design approval, production planning, material availability, foundation work, transportation, and site installation.
The basic modular house manufacturing process can be summarized as:
By moving part of the construction process into a factory, modular building combines controlled manufacturing with on-site installation. The specific construction method should be determined according to local building requirements, site conditions, transportation constraints, module dimensions, and installation requirements.
