The officer assessed the proposal against General Policy 2 of the Strategic Plan, which requires development to respect the site and surroundings in terms of siting, layout, scale, form, design, and l…
General Policy 2
GP2 permits development in accordance with land-use zoning if it respects site/surroundings in siting, layout, scale, form, design; does not adversely affect landscape/townscape character; and does not harm resident amenities or locality character. The officer tested the rear extension's design, scale, and amenity impacts, finding it compliant as it matches the existing house style, maintains height, and avoids overbearing, overshadowing, or overlooking.
Residential Design Guidance 3.2 Potential Visual Impact of an Extension upon the Existing House
Prefers pitched roofs over flat roofs when publicly visible, with exceptions for matching existing designs. The pitched roof extension matches the existing single-storey extension and main dwelling, acceptable despite limited public visibility.
Type A: Uplands
Considers neighbour amenity impacts like loss of light/overbearing, regulated by projection/depth; notes greater concern for terraced/semi-detached due to tunnel effect. As a detached dwelling with 3m projection and no height change, no overbearing or light loss impacts.
Residential Design Guidance 5 (Architectural Details)
Addresses architectural details like windows and finishes for coherent appearance with main dwelling. Extension designed in similar style to main house and existing extension.
Residential Design Guidance 7 (Impact on Neighbouring Properties)
Considers neighbour impacts including light/overshadowing, overbearing, and overlooking/privacy loss. No height change avoids overbearing/overshadowing; no new vantage points so no overlooking.
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.
