Why it was refused

  1. A Certificate of Lawfulness (proposed) cannot be issued on the basis that the proposed outbuilding does not constitute permitted development by failing to comply with Part (e)(ii) and Part (f) of Class E, Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended as the height of the building, when measured immediately adjacent to the building, would exceed the relevant heights. Full planning permission would therefore be required.
