Why it was refused

  1. Due to its excessive depth, layout and its physical link to the outbuilding, the proposed single storey rear extension element would result in a disproportionate and dominant structure that would harm the appearance of both the host dwelling and the surrounding area. The proposal would therefore be contrary to the principles of the National Planning Policy Framework, Policy 28 of the Sutton Local Plan 2018 and SPD4 'Design of Residential Extensions'.

From the council's decision notice.
