Summary of planning committee decision

Decided by Hertsmere Planning Committee on 18 Jun 2026.

26/0222/HSEApproved

What was proposed

The application proposed a single-storey side and rear extension to a two-storey semi-detached dwelling.

“DEVELOPMENT Construction of single storey side and rear extension.”

Officer report

The site

The site is on Ashfield Avenue and includes a dwelling with an existing side and rear extension, among two-storey semi-detached homes.

“The application site is located on the northeast side of Ashfield Avenue. The site comprises a two-storey semi-detached dwelling which has an existing side and rear extension. The surrounding area is made up of two storey semi- detached dwellings. Ashfield Avenue slopes downward towards the north. This creates level changes between the dwellings.”

Officer report

Officers’ recommendation

Officers recommended approval because the proposal was considered acceptable, with no harmful effect on visual or residential amenities or car parking.

“With regard to residential amenity the wraparound extension would have a depth of 3.35m which is in line with the Planning & Design Guide Part E 2006 and there is a 2m separation between the properties that mitigate impact to outlook. Therefore, the proposal is considered to not have a detrimental impact on the residential amenities of the neighbouring properties.”

“Overall, the proposal is considered acceptable and would have no detrimental impact in terms of visual and residential amenities or car parking and as such would comply with National and Local Planning Policy. Accordingly, the proposal is recommended for approval, subject to conditions.”

Officer report

Main planning effects

The extension was considered subservient, not highly visible from the street, and acceptable because its separation from neighbouring homes would limit effects on outlook.

“As the proposed extension would match the height of the existing side extension the proposal would not be highly visible from the street scene.”

“There have been no objections received from neighbours. Due to the proposed extension matching the depth of no.22’s rear extension, it is considered that the proposed extension would not have a detrimental impact on the residential amenities of the occupiers of this dwelling.”
