Single-storey rear extension at 2A Tarleton Road, Portsmouth
Summary of planning committee decision
Decided by Portsmouth Planning Committee on 4 Feb 2026.
What was proposed
A single-storey, flat-roofed rear extension would span the property’s full width and extend four metres, with roof lights.
“The proposal is for the construction of a single storey flat roofed rear extension (incorporating roof lights) of depth 4m, stretching across the full width of the property (6.5m). Given that levels within the site fall away to the south, the height of the proposed extension above natural ground level would be 2.87m at its northern end, increasing to 3.17m at its southern end.”
Officer report
The site and surroundings
The site is an end-of-terrace, two-storey dwelling near the junction of Tarleton Road and Winchcombe Road.
“The application site is an end-of-terrace, two storey, single dwellinghouse on the south- eastern side of Tarleton Road, close to its junction with Winchcombe Road.”
Officer report
Earlier planning history
Earlier permissions created new dwellings beside the original properties and approved related details and a parking amendment.
“19/01181/DOC - Application to seek approval of details reserved by conditions 5 and 6 of planning permission 18/00144/FUL (Bicycle storage and SAP) Approved 11/9/19”
“19/01190/NMA - Non-Material amendment to planning permission 18/00144/FUL to allow relocation of parking spaces to front of property A*17375 - Construction of 34 dwellinghouses Granted 18/6/51”
Officer report
What officers recommended
Officers recommended conditional permission because the extension was acceptable in design and residential amenity terms and complied with policy.
“The proposed extension is considered acceptable in terms of overall scale and appearance with regard to its relationship with the host property. Sufficient private rear garden area would remain to serve the dwelling. Being single storey and clad externally in matching brickwork it is considered an acceptable addition within wider area, and would not be readily seen from the public realm.”
“The proposed single storey rear extension is considered acceptable in design and residential amenity terms and compliant with policy and as such can be supported.”
