Prefabricated vs Modular Buildings

Prefabricated vs Modular Buildings

If you’re considering prefabricated buildings, it is almost certain that you intend to develop or expand an existing location. But wait; what about modular buildings? You may have heard this term used as well, and for the uninitiated, this can cause some confusion. After all, prefabricated and modular homes have been around for years, and their popularity continues to soar.

So, what is the difference between these two building types? Hopefully, this blog will shed a little light on the subtle nuances that distinguish prefabricated buildings from modular buildings. You’ll then be able to make an informed decision safe in the knowledge that you now know the difference between the two!


Prefabricated Buildings

To start with, consider for a moment that the term ‘prefabricated building’ is actually an umbrella term. It is commonly used to describe a wide range of different building types with modular being one of these types. A standard prefabricated building consists of panels and modules which are created within a controlled, factory-like environment.

This method of offsite construction helps maintain quality control, is great for the environment and won’t cause any unnecessary disruption to your site. It also greatly reduces the build-time as factors such as weather will not cause any unseen delays. When compared to traditional buildings, a prefabricated building can be designed, the parts created and transported and the building erected onsite in half the time.

This combined with the fact that all construction waste can be recycled in the factory makes prefabricated buildings a cost-effective and responsible choice.

Modular Buildings

Prefabricated Building

Ok, so we now understand what a prefabricated building is but what about modular buildings? What are these exactly? As with prefabricated buildings, the components used to create modular buildings including the modules themselves are built within a controlled, factory-like environment.

These modules are identified as box-like units which are put together to create the overall structure. They are designed in a way which conforms to the intended use and are fully customisable to suit a wide variety of purposes. Typically, a modular building can be comprised of a wide range of materials which includes:Modular Building

  • Wood Framing
  • Cold-formed Steel Framing
  • Hot-rolled Steel
  • Concrete
  • Combination Of The Above Material Assemblages

The most common approach to modular building construction is to take an ‘inside-out’ approach. This is exactly as the name implies – frames are constructed as planes, fitted as boxes and then finished from the inside-out.

As mentioned above, the internal space can be customised with a wide range of layouts, and these buildings boast all manner of features. Such features include mains water and power, data installations, service connections, premium insulation, cutting-edge double glazing, occupancy/ daylight sensitive internal lighting and much more.

Plus, these buildings can be finished off in a wide range of materials to give them a look of permanence. In fact, once finished they can be virtually indistinguishable from traditional buildings. For this reason, modular buildings have seen a sharp increase in popularity in recent years and are now one of the most frequently used forms of construction.

To Summarise

So, to summarise – all modular buildings are classified as prefabricated buildings but not all prefabricated buildings are modular. The term ‘prefabricated building’ is simply a broad way of describing a whole range of different types of structure. This distinction is important if you’re specifically searching for modular buildings.
