Officer report

The site and surroundings

The detached house has a large rear garden in a mainly residential area within the Osterley Park Conservation Area, with very poor public transport access.

“Figure 1 – Location Plan 2.1 The application site contains a two-storey detached, single family house with a large rear garden on the western side of Wood Lane. To the north is 152 Wood Lane, a two storey, detached house, and to the south is 148 Wood Lane, a two-storey semi-detached house. Nishkam School is to the east on the opposite side of Wood Lane. The rear gardens of 26 to 30 Leigham Drive are to the south and west and playing fields are to the west.”

Officer report

What officers recommended

Officers recommended approval because the scheme would provide housing, meet relevant standards and deliver energy improvements, despite minor conservation harm from losing the chimneys.

“The extensions would comply with the recommendations of the Hounslow Character, Sustainability and Design Codes SPD, Part A5 Residential Extension Guidelines with limited impacts to nearby residential properties and minor harm to the character and appearance of the site and Osterley Park Conservation Area. The proposal would secure a 78.73% carbon dioxide emissions reduction against a Building Regulations Part L (2022) baseline.”

“The application is recommended for approval subject to conditions.”

Main planning effects

The assessment found acceptable living conditions, accommodation, access, parking, drainage and sustainability, with biodiversity measures and other safeguards secured by conditions.

“Cycle Parking 7.52 All units would have their own long stay cycle parking storage area in the rear garden, and 2 short-stay visitor cycle parking spaces would be provided at the front of the site. The number of cycle parking spaces would be in line with London Plan cycle parking standards. The access to the rear cycle stores would be at least 1.2 metres wide. Full details of the cycle parking would be secured by a condition.”

“Figure 6 – Phase 1 Habitat Survey 7.65 These existing trees are not located near to the proposed extensions and should not be impacted as a resulted of the proposal. It would be expected that all existing trees be retained. The proposed site plan indicates that six trees would be planted in the communal garden. Details of tree protection measures and tree planting would be secured by condition.”

Who spoke at the meeting

The planning manager presented the report, while planning, development management and legal officers answered members’ questions and provided advice.

What members discussed

Members discussed chimney loss, tree replacement, possible air raid shelter preservation, biodiversity, bats, access, bins and parking before a councillor moved approval.

“There would be 14 long stay cycle parking spaces within the rear garden with sufficient access provided, along with two short stay cycle parking spaces at the front. This was in line with London Plan standards. Two car parking spaces would be provided at the front.”

“Cllr Tony Louki opened the debate, describing the proposal as superior to what had gone before. There had once been a beautiful garden on the site but that had previously been destroyed and was not germane to the Application. He called for heavy standard trees to be planted rather than saplings, for the air raid shelter’s preservation to be considered, for officers to ensure that the plans were fully enforced and biodiversity and conservation to be conditioned strongly…”
