General Policy 2
Requires development in residential zoning to respect site/surroundings in siting/layout/scale/design (b), not adversely affect townscape character (c), and not harm resident amenities/locality character (g). Officer assessed the rear extension as compliant due to its subservient scale, matching finishes, screening, and lack of amenity harm.
Environment Policy 35
Permits only development in Conservation Areas that preserves or enhances character/appearance and protects special features. In Selborne Drive Conservation Area, the rear screened extension was found not visible from public views, thus preserving character without inappropriate impact.
Planning Policy Statement 1/01 - Policy CA/2 (Conservation Areas)
Conservation area impact is a material consideration. Echoes ENV35; officer confirmed no adverse effect on special character due to rear location and screening.
Residential Design Guide 2019 Section 3.1
Guidance on extensions considering relationship to original building (materials/design), adjoining properties (building/roof lines), and original roof pitch/shape. Proposal matches existing white UPVC windows and is subservient.
Type A: Uplands
For single-storey rear extensions to semi-detached properties, key issues are depth/projection near boundaries causing loss of light/overbearing/tunnelling effects; unlikely support if >3m projection on narrower semis.

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 14 of the Town and Country Planning (Development Procedure) (No2) Order 2013 and to avoid the accumulation of unimplemented planning approvals.
