Why it was refused
- The proposed rear extension would extend from an existing side/rear extension, forming a wrap-around extension around the original side and rear walls of the dwelling, and would adjoin another previous side extension of the dwelling. The entirety of the resulting extension would result in a side extension, as well as a rear extension, that would have a width which would exceed more than half the width of the original dwellinghouse. The development is therefore not permitted under Class A (j)(iii) and (ja) of Part 1 within Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015, as amended. Planning permission is therefore required for the proposed development.
From the council's decision notice.
