Why it was refused

  1. The proposed external alterations to the existing garage are not considered to benefit from any general planning permission under Article 3(1) and Schedule 2 Part 1, Class E of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended). The conversion of the existing garage to provide independent living, sleeping and bathroom accommodation cannot be considered to be required for purposes incidental to the enjoyment of the dwellinghouse. Neither has it been demonstrated that the annex would remain ancillary to the existing dwellinghouse.
