Although they are not intended for use as permanent structures, portable buildings provide an ideal alternative where shelter or interior space is required and often they serve many of the same purposes than a conventionally built space would.
Portable buildings are commonly used as temporary offices on construction sites, as guard houses, as rural offices or medical buildings, as on-site changing rooms and as temporary housing in remote locations. Portable buildings are a type of modular building; however modular building is intended for more permanent long term use.
A portable building on a building site for example would only be required for a number of months, rather than many decades. Portable buildings are simple and compact, and are able to be moved as needed to different locations. The basic layout consists of a frame and wall panels, as well as a roof and installed floor.
Custom specifications can be made, but are often not worth the extra designing and fabricating costs as they are usually only required for temporary use.
There are numerous advantages to using portable buildings with the two biggest benefits being in the saving of time and money. Conventional building can take months from design to completion and there are numerous steps and processes along the way that can cause delays. A relocatable building is available for immediate use from the moment it is installed. This saves on costs in terms of raw materials, design and engineering costs and labor and workforce.
For spaces that are not required permanently, it is not logical to install a traditional building and therefore a portable office or space is the ideal solution. A further advantage to using portable buildings is the fact that because they are not intended for permanent installation, the structures are not required to abide by the regulations or tax burdens which traditional builders must follow.
This is a further time saving factor in the process of obtaining a space for office or personal use as a landowner does not need to go through further administrative work to obtain a building permit. The contractors who build the portable building are able to work from pre engineered building designs, and do not have to individually design each structure.
Furthermore, for short term temporary use, some manufacturers will rent or lease their portable or relocatable buildings, further saving a company money and time.
