Officer report

Officers recommended approval

Officers considered the works acceptable, policy-compliant and unlikely to harm the conservation area, neighbours, traffic or parking conditions.

“6.15Highways Officers have suggested that the applicant enter into a legal agreement with the Council to ensure that the occupiers of 14 Princes Gate Mews, except those with disabilities, would not be entitled to a residents parking permit. However, given that the garage does not meet the Council's minimum requirements for a garage it is unlikely that the garage is being used for vehicle storage off street.”
