Lack of planning permission can prohibit the erection of a brick-built construction, but modular buildings, which are classed as temporary buildings, are permitted.  That is why increasingly greater numbers of premises are actually comprised of modular offices even if they are intended to be permanent fixtures.

The loophole exists because modular offices can be moved if necessary. Any one unit can be hoisted onto a truck and moved. Therefore planning permission for the installation of a modular office is likely to be granted far more easily than for a more permanent structure.

This is why there is a common misconception that modular offices are temporary buildings. That may be true if you are thinking of the portable site offices you may have seen at construction sites or outdoor events, but they are not the only types of modular buildings available. The choice of styles and range of uses is almost limitless.

Modular offices can be leased or bought outright. The cost varies depending on the style and size of the unit and the length of the lease, if applicable. The array of combinations in modular offices that you can have is vast. You can combine open plan office space with toilets, showers, kitchen units, locker space and much more. That is the real beauty of modular buildings you can mix and match to suit your needs exactly.

The availability of different colors in modular building exteriors is particularly useful if it is to be used as an extension to existing buildings. Schools often need to expand the number of classrooms that they have to accommodate the growing number of students. Buying modular buildings can prove to be a cost effective means of achieving the extra space.

Modular offices also take very little construction time as they are normally delivered pre-constructed. Of course, the utilities need to be hooked up as appropriate, but there is certainly none of the mess and disruption that a traditional construction would bring.
Rather than wait for weeks, or even months, for the equivalent sized brick or concrete structure to be built, the modular building can be ready for use within a matter of hours.
