Hi, We are have just started a project to convert our attached garage into an office. We were a little late in finding out we needed building regs and have already had our concrete floor levelled with our living room floor. Only to find out it needed to be insulated. No other work has been carried out as yet. Can you advise if building regs will be issued if we compensate for insulation in other areas, is there any thin insulation/insulated flooring we could use? Please advise as we are new to this area! Hope you can help, thanks!
