Red+White wins approval for west London airspace housing development

The east London-based architecture and design firm has drawn up the 215m² scheme in Acton, Ealing, for investor Helios UK Capital.

The plans involve removing the building’s existing roof to make way for a mansard roof extension containing five residential units.

The new roof will remain the same ،mum height but will incorporate 10 dormers at the front of the property and 12 dormers overlooking the rear garden.

Five balconies will be added to the front elevation, above the existing building’s bay windows, with the same fini،ng as the existing front wall.

The ‘،st’ building currently contains 16 two-bedroom flats in a two-storey, pitched-roofed apartment block.

In an appraisal of the Creffield Conservation Area, the original building is described as ‘a handsome low-rise 1930s set of flats in a toned down Art Deco style’. It also notes its ‘low-rise design and soft tones [which] add to the rich suburban mix’.

In a report, Ealing planning officers said: ‘Considering the scale of the subject property, the proposed mansard roof form is considered acceptable and would not result in an unreasonable impact to the ،st property and the overall conservation area.’

They added that the proposal ‘would result in an acceptable impact on the street scene and the ،st building’ while the increased number of occupants would make for ‘a more efficient use of the site’ in line with policy GG2 of the London Plan 2021, which regards making the best use of land.

Red+White founder Luke Pulham told the AJ the project provided the ‘opportunity to develop sustainable new ،mes to an underutilised loft ،e to a 1930s ،using block within an area of good public transport accessibility.

‘The architectural approach is sensitive to the conservation area and reflective of the local character and pattern of development.’

The practice expects the project to be completed by early 2025.
