The original application 09/01550/B for a rear dormer and Velux windows for loft conversion was refused because the dormer would be an unduly prominent and incongruous feature contrary to General Policy 2 (GP2) of the Isle of Man Strategic Plan 2007. The appellant argued necessity for family accommodation, cited existing dormers and extensions nearby, and offered to amend the design. The council defended the refusal emphasizing the dormer's prominence, lack of similar features locally, and precedent risk. The inspector found the dormer conspicuous from Ballabrooie Avenue, out of keeping due to its size, form, and projection from below ridge level, distinguishing it from cited examples. The appeal was dismissed, upholding the refusal.
Precedent Value
Dismisses rear dormers that project prominently from below ridge level and are flush with façades in areas lacking similar features, even with GP2 presumption for extensions. Applicants must demonstrate subservience, matching local character, and avoid setting precedents for incongruous designs.
Inspector: G Farrington
