2 Lingfield Ave, Upminster , RM14 2PE

Main issues, as the Inspector framed them

• Whether the Council's decision to refuse to issue a certificate of lawful use or development was well-founded, turning on whether the building operation of converting the loft, including a hip to gable roof, rear dormer window and roof lights, with removal of the pitched roof over the existing ground floor rear projection, would have been lawful if begun on the date of the application

What decided it

The hip to gable alteration and rear dormer together exceeded the 50 cubic metre cubic content limit under Class B of the General Permitted Development Order and could not be offset by the kitchen roof alteration, which was not itself permitted development; conversely, the roof light closest to the boundary with 4 Lingfield Avenue was permitted under Class C with no applicable limitations.
