Prior to the introduction of prefab buildings, nobody would have thought of carrying an office or home around with them. The concept of modular and Portable Office was successful, as it became easier to purchase, install, and transport. This portable building can be made to use for a number of purposes. Majority of designers and engineers today are using transportable offices as functional buildings, for construction sites. The portable offices developed by us form a great solution. These can be easily transported to the work site, securely installed, utilities can be attached and then dismantled when the job is completed and moved to another site. These can be found in many organizations, industries, oil-drilling sites, construction sites, archeological digs, fair sites used as a temporary office space. One can even use this portable office as permanent office by setting it on permanent foundation.
