View guideWraparound extensions combine rear and side extensions in an L-shape. Most need planning permission — here’s when they can be permitted development and how to get them approved.
A wraparound extension combines a rear extension with a side extension to create an L-shaped addition. Whether permitted development depends on whether both elements individually comply with PD limits. In practice, most wraparound extensions need planning permission because the side element exceeds the Part 1, Class A limits or the rear projection exceeds the PD depth limit.
A wraparound extension has two components: (1) the rear element — assessed under Part 1, Class A (4m/3m depth, or up to 8m/6m under the LHES); and (2) the side element — must not exceed half the width of the original house, must be single storey.
| Factor | What Planners Assess |
|---|---|
| Streetscene impact | Side element visible from the street |
| Neighbour impact | Rear and side elements can affect adjacent properties |
| Scale | Combined mass should not be disproportionate |
| Materials | Should match or complement the existing house |
