Why it was refused

  1. A Certificate of Lawfulness (proposed) cannot be issued on the basis that the proposed part single-, part two-storey rear extension, when taken cumulatively, would have both a single storey and measure 7m in height and would be within 2 metres of the boundary of the curtilage of the dwellinghouse, and the height of the eaves of the enlarged part would exceed 3 metres. The proposal would therefore fail to comply with (f)(ii), (i) and (ja) of Class A, Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended. Planning permission would therefore be required.
