Alterations and erection of replacement extension to rear elevation

General Policy 2

GP2 permits development in line with zoning if it respects site/surroundings in siting, scale, form, design; does not harm landscape/townscape character or resident amenities. Officer tested rear extension's scale (5.9m wide x 2.3m proj x 2.1m high), matching finishes, and mono-pitch roof against these, finding compliance as it is not publicly visible, matches existing height, and improves privacy.

Type A: Uplands

Requires consideration of neighbour amenity impacts like loss of light/overbearing, regulated by projection/depth; notes greater concern for semi-detached due to 'tunnel effect'. Officer assessed projection (2.3m, matching existing) and height (2.1m, no higher than existing) as acceptable with no loss of light or overbearing impact.

Residential Design Guide 2019 Paragraph 3.2.2

Flat roofed extensions normally not acceptable unless matching existing flat elements, especially if visible. Proposal uses mono-pitched roof (not flat), aligning with guidance as existing had flat roofs but new design avoids visibility issues.

Residential Design Guidance 5 (Architectural Details)

Key considerations for architectural details like windows and finishes to achieve coherent appearance with main dwelling. Proposal uses matching finishes, casement windows, and concrete tiles, ensuring similarity in style.

Residential Design Guidance 7 (Impact on Neighbouring Properties)

Considers impacts on neighbours like loss of light/overshadowing, overbearing, overlooking/privacy. Proposal improves privacy by replacing conservatory glazing with solid wall on west elevation; no overlooking or light loss issues identified.
