General Policy 2
Requires development to respect site/surroundings in siting, layout, scale, form, design; not adversely affect townscape character or residents' amenity. Officer assessed extension's scale, flat roof (acceptable as not publicly visible), matching materials, and lack of amenity harm due to height, orientation and levels, finding full compliance.
Residential Design Guidance 3.2 Potential Visual Impact of an Extension upon the Existing House
Prefers pitched roofs over flat, especially if publicly visible, but allows exceptions for flat/low-pitched existing designs. Flat roof accepted here as not publicly visible from the south-facing rear location.
Type A: Uplands
Considers neighbour amenity impacts like loss of light/overbearing, especially 'tunnel effect' in semi-detached/terraced. Assessed projection/depth and location; no overbearing or light loss due to single-storey, site alignment and levels.
Residential Design Guidance 5 (Architectural Details)
Key considerations for architectural details like windows and finishes to achieve coherent appearance with main dwelling. Extension uses matching pebbledash render and appropriate fenestration.
Residential Design Guidance 7 (Impact on Neighbouring Properties)
Addresses neighbour impacts including light/overshadowing, overbearing, overlooking/privacy. No issues identified: no vantage points for overlooking, no overbearing.
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.
