Posted By Charley Farley-Trelawney Ian Always a moot point this one but not to difficult to clear up for you. In the first instance its hardly temporary if constructed from brick and block, life span say 350yrs!, secondly building control is strict and I can assure you without any doubt you will have required regs to build it in the first place, foundations, materials, height, roof construction, RSJ's etc etc, I would also be certain that if you have not applied for permission to build it you will need to file for retrospective, and work on the basis that they may ask you to take it down or alter it significantly, lots of questions here, does it fall within the local brown site building plan, is it overlooked, soil types etc etc. Temporary buildings generally are made of a product that is not permanent, wood, fibre glass etc etc, if your building is attached to an existing building then there are certain allowances for building, but again I can assure you; you far exceed them with this size. In answer to the question posed, you are the one that is in essence correct! All the best Charles
