Planning precedent report

Construction of a new single storey side extension on the western boundary of detached house and all associated works.

Single-storey flat roof extension to the side and rear, incorporating three rooflights. Partial demolition and height reduction of the front boundary wall. Relocation of the side access gate to the rear garden.

Proposal is to convert the existing attic space for occupation. Comprising of 1no bedroom, 1no en-suite and 1no wardrobe. Proposal includes erection of gable end wall to the side a flat dormer to the rear and a small Velux to the front. windows have been placed to match the existing surroundings while also providing a means of emergency escape should the access stairway become blocked. The dormer has been stepped back from the boundary wall of the neighbouring property in accordance with the SDCC House Extension Design Guide 2025. Dormer roof would be slopped approx. 1;80 to allow rain aggress via additional drainage which links into the existing drainage. 1no small Velux window is proposed to the front which also provides an additional emergency escape route, similar planning was sought and granted previously (2021), however with this application we have scaled back the extent of the proposal to only include the attic conversion. That planning reference was SD21B/0468. All external finishes will be such that they match the typical finishes within the area. The house is not overlooked directly from the rear. Sunlight / shadowing will not interfere with neighbouring properties due to the west facing orientation of the property. This proposal is similar to other dormers in the estate, one example is at SD19B/0465
