House refurbishment in Chiswick

It records the negative factors that Ealing’s 2007 appraisal and management plan identified, among them bulky and flat-roofed dormers, roof lights on front elevations, especially on unlisted houses such as the northern arm of Esmond Road, side and rear extensions that upset the permeability of the layout, and basements, called alien to the estate’s original design concept. It says these had not been significant since 2007 but a revised management plan would need to address them, and that enforcing existing controls remains an important priority, particularly for boundary treatments and low walls.

Ealing Council: Bedford Park Conservation Area update addendum, July 2020

Ealing’s review of conservation areas page says that on 19 November 2025 its planning committee approved changes, and lists Bedford Park under extended conservation areas; the page names no street. Ealing’s formal consultation, which closed on 31 January 2024, had proposed adding the western ends of Fielding Road and Blandford Road up to The Avenue, whose houses it said were of the same period and style as the eastern sections, and said Article 4 directions for any extended area would go through a separate statutory consultation.

Part B10, adopted on 14 May 2024, speaks for Hounslow’s side only. It says any extension must be proportional to the existing building and must avoid the loss of important green infrastructure in front and back gardens, and that replacement windows should match the originals in design and material. It encourages solar panels, air source heat pumps and secondary glazing but says they must be placed discreetly, and names internal wall insulation and draught proofing as other options. Its priorities for new development include, among others, the sensitive retrofit of existing building stock.

No single answer covers the street. Hounslow’s Strand on the Green appraisal, under the heading 52–70 Grove Park Terrace, calls these Grade II listed Georgian buildings that predate the railway and were once known as The Terrace, Strand on the Green, but its own schedule lists only Nos. 52 and 54, 56 and 68 and 70, with a garden wall and gateposts, at Grade II. The Grove Park appraisal describes other numbers in the street, so check the list entry for yours.

It can. Hounslow’s Old Chiswick appraisal names flooding as a threat to historic building fabric, says backland development should be avoided, and warns that additions against the wall behind the Chiswick Mall houses, or alterations to their rear, will affect the area’s appearance. Strand on the Green’s appraisal says the built-out area leaves little scope for new development beyond refurbishment and conversion. Hounslow’s Local Plan expects development beside the Thames to show it will not preclude raising or setting back the flood defence. The Hammersmith end of the Mall is covered on our Hammersmith pages.
