Modular buildings is a phrase that is used for a section of pre-constructed, usually rectangularly shaped, small building also called modules. These creations are stacked or placed next to one another in order to make what is essentially a complete multi-purpose building. They are also called prefabricated homes or permanent modular constructions, because that is the name of the method that is used to make them. While to some these may sound like a new method of building construction, the truth is that it has been around for a while, and it has improved with time to be able to make a few noticeable improvements on the old way buildings were put up.

The biggest difference there is between a modular building and a standard one would have to be that the former is built off-site under controlled conditions and later transported to the location that it is intended to occupy. This method allows the site work and the building construction to develop simultaneously, meaning that the expected time for the project to be finished is effectively cut in half. This also gets rid of the risk that the building schedule will be delayed for days and sometimes weeks by unpredictable factors such as bad weather conditions.

Many believe that this method of building construction would make a modular building flimsier and less stable than the ones constructed by regular means, but contrary to popular opinion they are also constructed with most of the same materials and to the same standard in order to meet all of the necessary durability requirements. On top of that, these types of constructions are also produced by eliminating a lot of the material waste that normally occurs on constructions of a similar scale, and most of the waste is eliminated as recycling materials anyway. They are also much more flexible since they can disassemble and the modules can be relocated relatively easily without having to make an entirely new building thus saving on materials, time and energy.

There are also a lot of different advantages that they posses in terms of design as well, like how they can be made to fit virtually any stable flat area and can fit the aesthetics of any of their on site counterparts easily without standing out. Add to that the reduced risk of accidents or injuries of the workers and you have a great cost-effective method of quick building construction that trumps any other method in almost every area.
