Why it was refused

  1. The kitchen nib is an original part of the house, so its side elevations are side elevations of the original house. As such, 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. Therefore, the proposal fails to comply with Class A.1 (j). In conclusion, the proposed work would require planning permission.

From the council's decision notice.
