Official record
Development description
An exempted development application was granted for my house in 2002 and it was duly constructed. Subsequently, an attic conversion was undertaken to create an additional office space/3rd bedroom. This space is accessed by a staircase, as can be seen on the drawings supplied. The new room measures 3045 x 3550mm, as shown. I would like to apply for exempted development status for this additional attic space.
