Why it was refused

  1. The proposed development would fail to satisfy the criteria contained in Class E, Part 1, Schedule 2 of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). This is because the outbuilding exceeds 2.5 metres in the case of a building, enclosure or container within 2 metres of the boundary of the curtilage of the dwellinghouse. Accordingly, the application under a Certificate of Lawful Development (Proposed) is refused. First Schedule (description of use/operations/matter) Construction of a single-storey outbuilding within the rear garden. Certificate of Lawful Development (Proposed).

From the council's decision notice.
