Measured Building Surveys in Richmond upon Thames

Where in Richmond upon Thames does a measured building survey actually get determined?

More of Richmond is designated than of any other London borough. The national register holds 85 distinct conservation area boundaries here covering roughly 3,172 hectares of a borough of 5,875 — the council's own published count is 72 (planning.data.gov.uk, retrieved 1 September 2026). Either figure means the same thing for a survey: assume the address is inside a designation until the map says otherwise, and scope the site visit accordingly. The table below gives each postcode district, its dominant stock, and the authority that determines an application from it.

What changes about a measured building survey in each part of Richmond upon Thames?

Two things get measured in this borough that go unmeasured almost everywhere else. The first is the facade in detail — reveal depths, cill and string course heights, brick coursing, the profile of a sash horn — because that is what a heritage statement has to describe and what a case officer compares against the neighbours. The second is levels. Where a site falls in Flood Zone 2 or 3, the Flood Risk Assessment works from finished floor levels tied to Ordnance Datum, and 16.93% of Richmond's 57.39 square kilometres sits in Zone 3 with 24.79% in Zone 2 (Environment Agency Flood Map for Planning, retrieved 1 September 2026). Those are map extents that decide whether a document is required, not a verdict on any house; the address is checked individually. But it means the levels are worth taking on the first visit rather than the second.

• Hampton (TW12) — a measured building survey in Hampton starts from georgian villas, edwardian terraces, 1930s semi-detached, and Hampton reads as Georgian and Edwardian villages. Georgian houses here are rarely square in TW12. Richmond Council assesses Hampton measured building surveys against its own Hampton character guidance, and the location plan we draw for Hampton references Hampton Court Palace.
• Whitton (TW2) — 1930s semi-detached defines Whitton, where 1930s semi-detached set what a measured building survey can do. 1930s semis here are dimensionally consistent across TW2. Any Whitton measured building survey is validated by Richmond Council, with Whitton station the usual Whitton reference point on the site plan.
• Ham (TW10) — a measured building survey in Ham starts from georgian villas, post-war estates, and Ham reads as Georgian common, post-war estate. Georgian houses here are rarely square in TW10. Richmond Council assesses Ham measured building surveys against its own Ham character guidance, and the location plan we draw for Ham references Ham Common.
• Mortlake (SW14) — Victorian and Edwardian terraces defines Mortlake, where victorian and edwardian terraces set what a measured building survey can do. Victorian terraces here have settled and bowed across SW14. Any Mortlake measured building survey is validated by Richmond Council, with Mortlake station the usual Mortlake reference point on the site plan.
• Richmond (TW9, TW10) — a measured building survey in Richmond starts from georgian terraces, victorian villas, and Richmond reads as Georgian centre, riverside conservation. Georgian houses here are rarely square in TW9. Richmond Council assesses Richmond measured building surveys against its own Richmond character guidance, and the location plan we draw for Richmond references Richmond Green.
• Twickenham (TW1, TW2) — a measured building survey in Twickenham starts from georgian fragments, victorian terraces, edwardian villas, and Twickenham reads as Georgian and Victorian riverside town. Georgian houses here are rarely square in TW1. Richmond Council assesses Twickenham measured building surveys against its own Twickenham character guidance, and the location plan we draw for Twickenham references Twickenham Stadium.
• Kew (TW9) — Georgian and Edwardian villas around the green defines Kew, where georgian and edwardian villas set what a measured building survey can do. Georgian houses here are rarely square across TW9. Any Kew measured building survey is validated by Richmond Council, with Kew Gardens the usual Kew reference point on the site plan.

What local planning policy applies to a measured building survey in Richmond upon Thames?

Heritage volume, and the grant rate behind it: Richmond Council decided 326 applications to alter or extend a listed building in the twelve quarters to March 2026 and granted 277 — 85.0%, below the London figure of 91.2% and 21st of the twenty-six boroughs whose caseload supports a rate (MHCLG planning statistics, retrieved 1 September 2026). A heavy heritage caseload and a comparatively hard one. Nearly one in seven such applications is refused here, which is the strongest argument for a survey that records what exists in enough detail to demonstrate what the proposal keeps. Twickenham Riverside, Barnes Village, Kew Green, Richmond Green and Ham Common are the areas that generate most of it.

What designation does to the route: inside a conservation area, article 2(3) withdraws the side-extension, cladding and roof-enlargement allowances, so a £249 prior approval in six weeks becomes a £548 householder application in eight. Given how much of this borough is designated, the useful survey question is not whether permitted development applies but which drawings the fuller route requires: a streetscene elevation, existing and proposed side elevations at the same scale, and enough section detail to show the relationship to the neighbours' eaves. Where the allowances do survive, a £274 lawful development certificate puts the fact on record before the question is asked at sale.

One number to read carefully: of 289 larger rear extensions notified to Richmond under the prior approval procedure over the same three years, 211 were granted and 78 refused, and not one was recorded as prior approval not required in any quarter. A blanket zero on that column across twelve consecutive returns is how a council codes its data far more often than it is a fact about what happened, so the 211 and the 78 are the figures to work from and the empty column should be ignored. Read that way, a little over a quarter of larger extension notifications here are refused, which is close to the London norm and a good deal better than the borough's reputation for scrutiny suggests.

Which neighbouring authorities border Richmond upon Thames?

• Hounslow — the northern and western neighbour, meeting Richmond at Isleworth, Whitton and along the Great Chertsey Road. The most permissive of the four on appeal: nearly half the householder appeals decided against Hounslow between 2016 and 2026 were allowed, the highest share in London. A refusal on either side of that line is worth a different calculation.
• Kingston upon Thames — the southern edge past Teddington and Hampton Wick. Kingston refuses larger rear extension notifications at 49.4%, the highest rate of any London borough, so on this boundary the notification route is worth testing on the map before it is designed to.
• Wandsworth — met at Barnes and Putney across the common and the river. Comparable Edwardian villa stock, and a borough that grants householder applications at above 90%, so the survey travels well across this edge even though the policy documents do not.
• Hammersmith and Fulham — touched only across the Thames at Barnes and Chiswick Bridge. Worth naming for one reason a Richmond riverside owner should know: it is the most extensively Flood Zone 3 borough in London, and the assessments prepared for sites on that stretch of river are read by both authorities against the same national policy.
