Designated 1998; appraisal 2021The Stamford Brook Conservation Area and its appraisal
Hounslow designated the Stamford Brook Conservation Area on 13 January 1998, and its appraisal, consulted on in autumn 2019 and adopted by the council in January 2021, says the area had not been altered or extended since. The appraisal places it in the north-east part of Chiswick and explains that its eastern boundary is irregular because it partly follows an old ditch along the former parish boundary between Chiswick and Hammersmith. To the east lies Hammersmith and Fulham’s Ravenscourt and Starch Green Conservation Area.

Its guidance is brief and direct: dormers are very visible and should be carefully considered, uPVC is not recommended for windows and doors, strong front boundaries should be kept and new crossovers for vehicle access and parking resisted. It sees no obvious potential in this very tightly knit area beyond repair and small rear extensions. It also notes that the council could control the replacement of doors and windows, new window openings and changes to boundaries through an Article 4 direction, presenting that as a power the council could use.

HMO direction 2023; basements 2018Article 4: Hounslow and the Stamford Brook Road stretch
Hounslow says its conservation-area Article 4 directions apply to the Gunnersbury and Bedford Park conservation areas, so none of them covers the Stamford Brook Conservation Area. Its borough-wide direction on turning houses into small HMOs was confirmed on 8 August 2023 and came into force on 4 September 2023.

On the Hammersmith and Fulham side, the council’s summary of Ravenscourt and Starch Green Direction No. 1 lists 2–10 (even), 5 and 7, and 9–25 (odd) Stamford Brook Road for alterations to the front roof, gables and dormers, coverings included, changes to rear roof coverings and the painting of unpainted brickwork. Direction No. 4 lists 2–10 (even) and 9–25 (odd) for alterations to the front elevation. Both summaries describe themselves as outside the legal documentation, so it is the wording of each direction that governs. Hammersmith and Fulham also has a borough-wide basement direction, in force from 26 April 2018.

Plans of 2015 and 2018The adopted Local Plans
For a Hounslow address, the adopted Local Plan dates from 15 September 2015, and the appraisal names its policies CC4 Heritage, SC7 Residential Extensions and Alterations and CC1 Context and Adopted Character as relevant. Its proposed replacement, the Hounslow Local Plan 2020–2041, is not adopted: the examination hearings closed on 2 July 2026, and the Inspectors expect to say more about the next steps in November 2026.

Hammersmith and Fulham adopted its current Local Plan on 28 February 2018, and that plan is the basis for planning decisions at its Stamford Brook Road addresses. Its Policy DC4 expects an extension to be subservient and never to dominate the parent building, and Policy DC11 stops a basement reaching under more than half the depth of the garden. A Regulation 18 draft of a replacement plan has been out to consultation, but it remains an emerging document, not adopted policy.

The two Grade II houses in the Hounslow conservation area are The Brook on Stamford Brook Road, listed on 11 July 1951, and Stamford Brook House with its wall, on Stamford Brook Avenue, listed on 21 May 1973. Historic England describes The Brook as an eighteenth-century house of brown brick, originally two cottages, and records it as Lucien Pissarro’s home and studio from 1901 until his death in 1944; Hounslow’s appraisal says Stamford Brook House was built about 1743. Hounslow’s local list here is a cattle trough and two boundary markers.

Across the boundary, 9 and 11, 15, 17 and 19, and 21 and 23 Stamford Brook Road were listed Grade II on 14 February 1985. Historic England describes 9 and 11 as a mid-19th-century pair of semi-detached cottages and 17 to 23 as stuccoed semi-detached cottages with hipped slate roofs, and Hammersmith and Fulham’s character profile, approved in 1997, places them in the Ravenscourt and Starch Green Conservation Area. Separately, 5 and 7 and 2–10 (even) Stamford Brook Road and St Mary’s Court, a former church, appear in Hammersmith and Fulham’s Local Register of Buildings of Merit as it stood in August 2015. The council cautions that the directions and Buildings of Merit named in the profile are not the full set, and refers questions to its Urban Design and Conservation Team.

Before new windows are ordered, a roofer is booked or any ground is dug, establish which consents the exact address needs, treating each one on its own terms: planning permission, including where a Ravenscourt and Starch Green direction covers a Stamford Brook Road house; listed building consent for The Brook, Stamford Brook House or the listed Stamford Brook Road cottages; the conservation-area controls and guidance of whichever council covers the address; Building Regulations approval; the freeholder’s permission wherever a lease calls for it; and, for work the Party Wall Act covers, notice to the neighbour. A Hammersmith and Fulham address also falls under that council’s borough-wide basement direction.
