Detached garden outbuilding at 5 Cavendish Avenue, Welling

Summary of planning committee decision

Decided by Bexley Planning Committee on 3 Sept 2026.

26/00868/FULApproved

The site and building

The site is part of a semi-detached pair, and the outbuilding would be about 6 metres wide, 7.9 metres long and 4 metres high.

“The application site is part of a semi-detached pair located towards the north of Cavendish Avenue, on the east side of the road. The proposal site is not within the Metropolitan Green Belt, Conservation Area nor is it a statutorily or locally listed building. Land Designations…”

Officer report

Earlier permission

An earlier application was granted for an outbuilding of the same height and width, while this proposal increased its depth from 4.5 metres to 6 metres.

“The dimension of the outbuilding is approx. 4m in ridge height, 2.5m in eaves height, 7.9m in width and 6m in depth. The proposed outbuilding would not have an adverse effect on the street scene as it is not visible from public viewpoints. Due to the siting and separation from the shared boundaries and limited dimensions, it is viewed as a subservient addition within the site and does not adversely impact the character or appearance of the existing dwelling.”

“Furthermore, the materials used match the materials of the properties in the area and the neighbouring outbuildings. The outbuilding is sited closer to the site boundaries than would be achievable under permitted development, for a building of this height, being located approximately 0.2-0.5 metres from neighbouring boundaries. However, planning permission was previously granted under reference 25/01842/FUL for an outbuilding of the same height and width in this location.”

Officer report

Why officers supported it

Officers considered the design acceptable, with no harmful effect on the area’s character or neighbouring amenity, subject to conditions.

“The key issues to consider include: Design and impact on the character and appearance of the area and the impact on neighbouring amenity. Design and Impact on the Character and Appearance of The Area…”

“The proposed outbuilding is of an appropriate size and design for its intended use within this residential area. The proposal is therefore considered to accord with London Plan Policy D4 and Bexley Local Plan Policies SP5 and DP11 regarding achieving high-quality design.”
