General Policy 2
Requires development to respect site/surroundings in siting, layout, scale, form, design, landscaping; not adversely affect landscape/townscape character or local residents' amenity. Officer assessed proposal complies as extensions match existing style, no visual harm to street scene (flat roof not visible), and no amenity loss. This tipped balance in favour of approval.
Residential Design Guidance 3.2 Potential Visual Impact of an Extension upon the Existing House
Prefers pitched roofs especially if publicly visible, but exceptions for flat/low pitched where existing has similar. Applied to rear flat roof, which is not publicly visible and blends with existing rear, so acceptable.
Residential Design Guide section 4.1
Front extensions have greatest street scene impact; should appear as if original design. Porch/terrace replacement uses matching materials and style, considered appropriate.
Section 4.4 Extension to Side Elevation (RDG 2019)
Considers visual appearance and neighbour amenity; regulate by location, size, style. Side extension set back, matches architecture, avoids terraced appearance with garage.
Type A: Uplands
Addresses neighbour amenity like loss of light/overbearing via depth/location. Rear extension regulated to avoid impacts.
Residential Design Guidance 5 (Architectural Details)
Architectural details like windows/finishes should match main dwelling for coherence. Proposal uses matching casement windows, half-timber, brick/render.
Residential Design Guidance 7 (Impact on Neighbouring Properties)
Considers loss of light, overbearing, overlooking; uses 20m guide for overlooking. Front terrace >20m from neighbours, no privacy loss.
