General Policy 2
Requires development to respect site/surroundings in siting, scale, design and not adversely affect amenity or locality character (criteria b and g). Officer found extension subservient, rear-positioned not harming streetscene, materials matching, and no undue amenity harm despite acknowledged initial overbearing feel.
Environment Policy 22
Prohibits development unacceptably harming amenity via pollution including light disturbance (iii) and surface/groundwater (i). No overlooking/light pollution harm from amended roof lights and no side openings; drainage to existing system via condition. Single-storey scale not overbearing to refusal level.
Time limit
The development hereby approved shall be begun before the expiration of four years from the date of this decision notice. Reason: To comply with Article 26 of the Town and Country Planning (Development Procedure) Order 2019 and to avoid the accumulation of unimplemented planning approvals.
No openings near boundary
No openings shall be introduced to the walls or roof adjacent to the boundary with no.30. Reason: For clarity and to protect residential amenity in respect of overlooking and light disturbance in accordance with Environment Policy 22 (iii).
Guttering and drainage
Upon completion of the roof and prior to the extension being first brought into use the guttering around the extension shall be installed and working to direct surface water from the roof into the existing surface water management drainage of the site. The guttering shall be maintained and retained for the lifetime of the development. Reason: For clarity and to ensure surface water is managed within the site in accordance with Environment Policy 22 (i).
no objection provided the development does not prohibit the storage of waste bins within the curtilage of the property
Neighbours at 30 Ashberry Avenue formally object to planning application 25/90530/B for a single-storey extension at 32 Ashberry Avenue due to scale, design, amenity impacts, drainage concerns, and potential breach of restrictive covenants.
Key concern: Loss of light, overshadowing, and overbearing impact on neighbouring residential amenity
Residents of 30 Ashberry Avenue
ObjectionWe strongly urge the Planning Department to refuse this planning application.; The proposed height and type of roof for the extension are out of character with the existing properties and the surrounding area.; The height and length of the proposed extension... will undoubtedly reduce the natural light entering our property.; We believe the proposal may not satisfy the restrictive covenants listed in the property deeds.
