What is mean by Prefab Buildings?

A prefabricated steel building is a broad term that describes a building structure or it’s a method of construction either partially or fully off-site. Its Components are constructed and delivered to a location where they are installed or assembled to form the final building. In short, The term prefabricated buildings refer to a broad number of varying construction types that fit within the main category.

The 3 Types Of Prefabricated Buildings are:

Types Of Prefabricated Buildings


  1. Modular: three-dimensional components built almost entirely in a factory environment and delivered to the site for installation. Also known as the sectional, compilation of systems are 3-dimensional structural units that will mix at the site with other units resulting in a complete building.
  2. Panelized: 2D panel homes will partially install in a factory environment. after that, it will deliver to the site for assembly and construction.
  3. Hybrid Prefab: A combination of 2D panel and 3D modular construction. A Hybrid system is advantageous for bespoke component requirements. So, it can move up fast and deliver to the site because of site challenges.

2D Panel Prefab buildings can also refer to precut, panelized systems, flatpack homes, kit homes, and non-volumetric buildings.

3D Modular Prefabricated steel buildings can also be referred to as sectional, volumetric, DfMA (Design for Manufacture & Assembly) and PPVC (Prefabricated Prefinished Volumetric Construction)

Advantages of Prefabricated Buildings

  • Typically prefabricated buildings can be ready in 14 – 16 weeks and it can install at the location site in 1 day.
  • Prefabricated buildings are cost-efficient. so, it’s a construction that speeds up the overall process.
  • it will Improve building quality and more airtight structures can achieve by building the home in a controlled construction environment.
  • Improved environmental impact. Modular construction vastly minimizes the amount of on-site waste and land disturbance.

Types Prefabricated Buildings with reference to the construction industry hasn’t gained a lot of popularity. So, the reasons for that attribute are:

  • Not many players offer complete building solutions.
  • Hefty transportation costs.
  • High risk of damage in transit.
  • Skilled labor demands for assembly.
  • Cautious handling of components.
