Hillingdon Council approved both applications which will intensify the use of one building by splitting it up while converting another family home into two smaller flats
Two large family homes in Hillingdon are set to be converted into flats, with one of the properties carved up to house up to 14 people in four individual units.
A house at 271 Long Lane in Hillingdon will soon contain four flats. This is after Hillingdon Council approved plans to convert the property to substantially increase the number of people who can live in the building in new self-contained properties.
In planning documents, the applicant describes the house as having “an unusually large amount of residential floor space for a single-family dwelling”. The property spreads across a ground floor, first floor and loft level, all of which contain “habitable accommodation”.
The four proposed flats are distributed across the three storeys of the existing building. Flat 1 and Flat 2 will be on the ground floor; Flat 3 on the first floor; and Flat 4 as a two-storey maisonette occupying part of the first floor and the full loft level.
There will be two one-bedroom flats, one two-bedroom maisonette and one three-bedroom flat. Planning documents state that it’s intended that the new properties combined will house up to 14 tenants accounting for two people per room, though it would depend who moves into them. It’s unclear from planning documents whether the homes would be put up for private sale or rent.
Council officers argued that the development would “provide good quality living conditions and would be acceptable with regards to impacts on the character of the area, neighbouring residential amenity, highway safety and parking”.
Living space is also set to be provided in each flat, alongside a car parking space and cycle storage. The plans were granted approval on Tuesday, August 25.
A Hayes property, 163 Lansbury Drive, is also set to be converted into flats following council approval. The former family home will house a studio and a separate one-bedroom flat with a private garden.
The upper floor flat will not have any dedicated outdoor space. This was deemed acceptable due to the proximity to Belmore Playing Field a 16-minute walk away.
There are also proposed rear extensions, although these are not expected to be visible from the street. Council officers anticipate no impact on surrounding properties from loss of outlook or increased sense of enclosure.
Officers said: “In reaching this decision, positive weight is afforded to the modest contribution that the proposal makes towards the borough’s housing supply.”
This comes as Hillingdon cannot demonstrate a five-year housing supply – it has a two-and-a-half-year supply as of April 1, 2026.
A parking design and management plan will allocate the off-street parking space solely to the ground floor flat, banning any further lease or sale of the spot. The building will also provide four cycle parking spaces.
