The proposal involves development under Section 55 of the Town and Country Planning Act 1990, but the Local Planning Authority is not satisfied that the proposal as detailed in the submitted drawing nos. 2020/02/Nrt/1, 2020/03/Nrt/1 and 2020/03/Nrt/1 can be classed as permitted development. This is because the proposal would not comply with A.1 (f)(i) of Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 as the proposal would extend beyond a rear wall of the original dwelling by more than 3 metres.
