Why it was refused

  1. The proposed single storey rear extension as described in the submitted information; Application Form. Existing Site Plan, Block Plan, Elevations and Floor Plans (Drawing No.101). Proposed Block Plan, Elevations and Floor Plans (Drawing No.200), would not comply with Schedule 2, Part 1, Class A.1 (j) of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). The development would not therefore be lawful and planning permission is required.

From the council's decision notice.
