Prefabricated architecture, also known as prefab, involves constructing buildings or portions of buildings off-site and then transporting them for final assembly. Prefab construction has several benefits, including keeping construction sites cleaner and safer, saving time compared to traditional on-site building, and allowing for easy relocation of structures. Some common prefab techniques include timber framing using pre-assembled wood panels, steel framing of components in a factory, and repurposing shipping containers as prefabricated housing or other buildings. Prefab architecture can help reduce greenhouse gas emissions from construction and is a promising solution for addressing climate change issues.

4.  Greenhouse gas (GHG) emissions in the construction stage will be
more relatively significant over time
 Different construction methods influence GHG emissions in the co
nstruction phase.

5. What is prefab
building or
architecture?
 The term “prefabricated” is given to an array of buildings and
fabrication methods that are manufactured off-site and then
relocated to the construction site for final integration and
assembly.

6. History
 Prefabricated housing was popular during the SecondWorld
War due to the need for mass accommodation for military
personnel.
 . John Rollo described in 1801 earlier use of portable hospital
buildings in theWest Indies

7.  McDonald's uses prefabricated structures for their buildings, and
set a record of constructing a building and opening for business
within 13 hours (on pre-prepared ground works)

9. Benefits
 prefab helps keeps the site safe and organized
 Because components were already individually assembled at a
separate warehouse, this keeps the actual project site clean and
clutter-free
 Save time
 With prefabrication, there is less risk for problems with dirt,
moisture, and other environmental hazards because workers
create sub-assemblies in factory-controlled environments.
 Modular construction can be easily be disassembled and relocated
to different sites
 Portable construction takes significantly less time to build than
on-site construction

10. Types
 Timber Framing
 A timber framing panel is first built in the factory, and then
transported to the location of the onsite construction.

11.  Steel Framing
