2. What, exactly, is a modular home?
• A modular home is one that is built indoors in a factory-
like setting. The finished products are covered and
transported to their new locations, where they
are assembled by a builder.
• A modular home is not a mobile home; it is simply a
home that is built off-site, as opposed to on-site. These
homes are often called factory-built, system-built or
prefab (short for prefabricated) homes.

3. How do modular house differ from house built on site?
• Modular homes are built indoors, they can be
completed in a matter of a few weeks, as opposed to
months.
• They don’t see the typical on-site delays caused
predominantly by the weather.
• Modular homes must conform to specific rules,
guidelines and building codes that often surpass
those of traditional on-site homes.

6. Construction process
• Modular components are typically constructed indoors
on assembly lines.
• The entire process of modular construction places significance
on the design stage.
• This is where practices such as Design for Manufacture and
Assembly (DMA) are used to ensure that assembly tolerances
are controlled throughout manufacture and assembly on site.
• The use of advanced CAD systems, 3D printing and
manufacturing control systems are important for modular
construction to be successful. This is quite unlike on-site
construction where the tradesman can often make the part to
suit any particular installation.
• Modules' construction may take as little as ten days but more
often one to three months.

11. Materials
• The materials used in modular homes are the
same as site constructed homes.
• Wood-frame floors, walls and roof are the
most typical. Some modular homes include
brick or stone exteriors, granite counters and
steeply pitched roofs.

14. •A factory-built home starts out as sections that
have been built in a climate-controlled area.
•The finished sections are transported to the
building site and then assembled with cranes.
•This process resembles a child building with Lego
blocks.
•Modular homes cannot be moved after they have
been placed and set on their foundations.

15. Finishing and assembling

16. • Modular homes offer hundreds of
personalized features that include (but are not
limited to) ceramic floors, solid-surface
countertops, various cabinet styles and wood
species, exterior finishes, plumbing fixtures
etc.

17. Are modular houses are more expensive than those built on site?
• Prefab homes can typically save you quite a bit of
money. Because they are constructed in a factory, they
can be built fairly quickly in a matter of weeks, as
opposed to months because there are no weather
delays.
• Furthermore, all inspections are performed at the
factory during each phase of construction by a third-
party inspector, and are completed before the homes
are transported to their permanent locations.

18. Advantages
• Environment friendly process:
Modular construction reduces waste and site disturbance
compared to site-built structures.
• Indoor construction:
Assembly is independent of weather, which can increase
work efficiency and avoids damaged building material.
• Speed of construction:
Modular construction allows for the building and the site
work to be completed simultaneously. This saves lots of time
and due to that we get faster return of our investment.

19. • Flexibility:
One can continually add to a modular building, including creating
high rises.
• 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.
• 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. Waste can be recycled.
