General Policy 2
GP2 requires development in accordance with land-use zoning that respects site/surroundings in siting, layout, scale, form, design, landscaping; avoids adverse impacts on landscape/townscape character, resident amenities, and incorporates safety/energy best practice. Officer assessed proposal against criteria (b), (c), (g), (m), (n), finding it compliant as extension respects residential character, passes amenity tests, and uses contemporary design acceptably in built-up area per para 8.12.1.
Residential Design Guide 2019 - Dormer extensions
Requires consideration of neighbour amenity impacts like loss of light/overbearing, regulated by projection/depth; single-storey unlikely if >3m projection, greater concern for terraced/semi-detached. Officer confirmed depth/position passes 45-degree test, no overshadowing/overbearing.
Residential Design Guide 2019 - Decking/terraces
Recommends parapet and architectural detailing; contemporary design acceptable in certain circumstances. Officer found parapet connects seamlessly to dwelling, justifying flat roof.
