Why it was refused

  1. Development is not permitted under Schedule 2, Part 1, Class A.1 (j) (iii) of the General Permitted Development Order 2015, as amended (GPDO) where the enlarged part of the dwellinghouse would extend beyond a wall forming a side elevation of the original dwellinghouse and would have a width greater than half the width of the original dwellinghouse. The proposal would be contrary to (j)(iii), therefore it is not permitted development and would require planning permission.

From the council's decision notice.
