Following discussions with Enforcement Officers at Wokingham Borough Council, an application was submitted for the use of a barn as B1c engineering operation. The barn itself was firstly demonstrated to be lawful through the provision of historic aerial photographs, but the current use required the benefit of retrospective planning permission. Working with Developers Land Surveys (www.developerslandsurveys.co.uk) to prepare plans of the building, a statutory declaration by the business owner was prepared to explain the nature of the use. Given the location of the barn within a wider, established commercial site, retrospective planning permission was granted.
