This decision has been made for the following reasons(s) The proposal accords with the Isle of Man Strategic Plan 2016 and the Area Plan for the East by delivering a proportionate extension within an established residential curtilage, consistent with Paragraph 8.12.1. The design respects the architectural integrity of the existing dwelling,

maintains the verdant and low-profile character of Sunnybank Avenue, and avoids visual intrusion, satisfying Strategic Policies 3 and 5 and Environment Policy 42. While the separation distances (16.2 m and 18.8 m) fall below the 20 m guideline in the Residential Design Guide, the single-storey form, boundary screening, and restrained massing mitigate any potential impact on privacy and outlook, ensuring compliance with General Policy 2(g). Access and parking remain unchanged and meet Transport Policy 7 standards. No objections have been received, and the scheme represents efficient use of land without compromising character or amenity.
