Measured Building Surveys · SW14 Mortlake
Richmond controls the Mortlake and East Sheen conservation areas; the former Stag Brewery is a major local redevelopment.
SW14 is Richmond upon Thames, the most designated borough in London: 85 conservation areas covering 3,172 hectares. A survey here has to establish which side of a boundary the property sits on before anyone can say whether permitted development applies at all.

Mortlake SW14 — local contextIf the job is not confined to this district, the borough-wide page covers the same service: measured building surveys in Richmond upon Thames.
A measured survey records the Mortlake property as it actually stands — every wall thickness, opening, floor level and boundary line — and everything designed afterwards is built on it. The older terraces and villas around Mortlake, East Sheen and the North Sheen fringe are rarely square anywhere, and an error found at survey stage costs nothing, while the same error found after Richmond Council has validated the application costs a resubmission.

Across Mortlake, East Sheen, Sheen, North Sheen fringe in SW14, the dominant property is edwardian and inter-war terraces and semis around mortlake and east sheen, with larger houses toward richmond park. That stock shapes what measured building survey looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Richmond Council judges each on design quality and neighbour impact. We survey the specific Mortlake property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SW14 streetscape.
Housing stock in SW14: Edwardian and interwar terraces and semis fill Mortlake and East Sheen, with the houses getting larger as you approach Richmond Park. Across the borough as a whole, 20.3% of dwellings pre-date 1900 and 17.5% went up between 1900 and 1918, on VOA stock figures at 31 March 2025.
Within the district: Mortlake, East Sheen, Sheen, North Sheen fringe.
Streets we know in SW14: the East Sheen streets (Christchurch Road, Sheen Lane), the Mortlake riverside and the Palewell streets. Each road has its own building line, boundary treatment and precedent that Richmond Council weighs when assessing a measured building survey scheme.
Conservation areas: the designations that fall inside SW14 are Mortlake and The Green, East Sheen and Sheen Common. Alter an external face inside one and you are normally into a full application, with a Heritage Statement to go with it.
Getting around SW14: Mortlake and North Sheen stations run into Waterloo, and Richmond station a little further out adds the District line.
Regeneration: the Stag Brewery redevelopment sits at the heart of SW14, and the planning policy and design expectations written around it reach beyond the site boundary.
What SW14 property is worth: 267 SW14 sales went through the Land Registry across 2025, and the middle one of them was £970,000. Contains HM Land Registry data (c) Crown copyright and database right 2026.
The authority and its workload: every SW14 address falls to the London Borough of Richmond upon Thames, which reached decisions on 6,504 applications right across its caseload in the three years to last March, and recorded 1,323 certificates of lawful development in the same period. Its housing stock came to 85,800 homes on the March 2025 valuation return. Contains public sector information licensed under the Open Government Licence v3.0
Why the depth matters here: a refusal share near a fifth makes the permitted development question worth settling early. Class A of the 2015 order allows a single-storey rear extension of 3 m on a terrace or semi and 4 m on a detached house before any application is needed, and on the Mortlake terraces the original rear wall is rarely where the deeds suggest — which is the whole argument for surveying it rather than scaling it off an old plan.
Borough character: Richmond runs one of the larger sets of conservation area designations in London, and the Royal Parks and the Thames corridor pile further heritage constraint on top. Design quality gets read closely: 818 of the borough's 4,125 householder decisions were refusals.
A chartered technologist walks the Mortlake property with a Leica Disto, setting the BLK360 down where a scan is worth having. Ninety minutes usually clears a terrace of two or three bedrooms.
The drawing is produced in AutoCAD, or in Revit where the job wants a model, at 1:50 or 1:100 and accurate to plus or minus 3mm point to point. Annotation covers each room, each opening, the fittings and whatever services are visible.
Four elevations and the cross-sections through them. Richmond wants the elevations for a planning application; a party wall award and any structural design need the sections.
Scanning with the BLK360 produces a complete 3D point cloud. It pays for itself on the older Mortlake houses, on listed fabric, and on bay-fronted geometry that never measures square.
Four formats leave with you: DWG, RVT, PDF, IFC. Nobody downstream, architect or engineer or builder, has to ask for a conversion.
An accuracy report to RICS expectations comes with it: accurate to plus or minus 3mm point to point and within 5mm absolute across the building. That is what a case officer, a party wall surveyor acting for next door, an insurer, or the council itself will all take as the warrant for a drawing.
Single planning or building-regs submission.
Planning + building regs + structural.
Listed, conservation or complex sites.
Yes. Side-return, rear and loft work all sit comfortably on the Edwardian and interwar houses along Christchurch Road and Sheen Lane. Away from the conservation areas much of that work never needs an application at all, with a Lawful Development Certificate recorded afterwards as the proof. Route first, drawings second, and the drawings answer Richmond's validation checklist.
The old Stag Brewery at Mortlake is being rebuilt as housing, a school and riverside public space — among the largest schemes Richmond has consented. For a house project a few streets away it changes nothing directly: what binds you is the permitted development envelope and, where it applies, the conservation area boundary. We check both against your address.
Usually yes on the semis and terraces — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate, provided you're not in the Mortlake or East Sheen conservation areas. We check the constraints for your road and draw it for Building Control.
Half of SW14's 2025 sales cleared £970,000, on Land Registry price-paid figures, with Richmond Park a short walk from much of the district. Whether a side-return or a loft returns more than it costs depends on the house and on what you would otherwise pay for the same floor area, and nothing in the public data settles that for you.
At a district median of £970,000 across 267 SW14 sales last year on the Land Registry's price-paid returns, the cost of a set of drawings barely registers against the asset. Richmond Council's statutory charge is separate and comes on top. The householder application fee in England is £548, rising to £610 for a full application. We quote the drawings as a single fixed figure, and there is no charge for the site visit anywhere in SW14. Source: HM Land Registry Price Paid Data
Reckon on three to four weeks between instructing us and the application going in on an SW14 job across Mortlake, East Sheen and the North Sheen fringe. The survey happens in the first of those weeks. Drawings follow, and so does a round of your amendments, which together take up most of the next fortnight. After that comes validation and Richmond's own statutory clock, which runs eight weeks for a householder case. Anything an officer asks while it runs, we answer.
All of SW14 falls inside Richmond upon Thames, so Richmond Council decides every application here and there is no boundary question to settle. Nothing under Article 4 applies across the whole of Richmond to remove householder permitted development from a family house; a condition attached to an earlier consent can achieve exactly that at a single address, however. Mortlake and The Green, East Sheen and Sheen Common are the SW14 conservation areas, and inside them external work goes the full-application route with a Heritage Statement. We check the constraints on your exact address before quoting.
Nearly always. Cutting a new opening, dropping in a steel, forming a loft floor or touching foundations all require Building Regulations approval. Three parts of the regulations are engaged: A for structural adequacy, B for getting out of the building in a fire, L for thermal performance. It goes through Richmond Council Building Control or an approved inspector. Because terraces and semis make up most of SW14, a party wall notice has to be served and answered before any beam is installed. Our Complete package covers the regulations submission and the notices together.
In money terms it is, on the district's 2025 sale prices. The larger exposure is a scheme that was never approved, or one that cannot be signed off: that is what stalls a sale in SW14, and it is why the drawings need to be council-ready and the Building Control file clean.
Extensions on a boundary plot can involve two authorities. Everything we draw and submit is listed for SW13, TW1, TW2, TW9, TW10, TW11 and TW12.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
The table sets out the SW14 area we survey in, what the housing is, and who validates an application built on that survey. Fees in it are the 2026 statutory scale for England, payable to the council and unrelated to what a survey costs.
| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|---|---|---|
| SW14 | Mortlake / East Sheen | Edwardian villas, 1930s semi-detached | SW14 does not cross a borough boundary at any point, which puts Richmond Council in charge of validating every application drawn from a survey in the district. |
| SW14 | East Sheen | Edwardian villas, 1930s semi-detached | East Sheen lies inside SW14 and inside Richmond upon Thames, so Richmond Council is the authority for anything drawn from a survey here. |
| SW14 | Mortlake | Victorian and Edwardian terraces | Mortlake is SW14 throughout, with Richmond Council determining every application that follows from a survey at one of its addresses. |
| SW13 | Barnes | Georgian villas, Edwardian terraces | Adjoining district to SW14. Surveying needs no consent here either — Richmond upon Thames has no say in it, and the survey is the same record whichever side of the line the property sits. |
| TW1 | Twickenham | Georgian fragments, Victorian terraces, Edwardian villas | Adjoining district to SW14. Surveying needs no consent here either — Richmond upon Thames has no say in it, and the survey is the same record whichever side of the line the property sits. |
| TW2 | Twickenham / Whitton | Georgian fragments, Victorian terraces, Edwardian villas | Adjoining district to SW14. Surveying needs no consent here either — Richmond upon Thames has no say in it, and the survey is the same record whichever side of the line the property sits. |
Ridge heights, wall construction and back-plot depth are not consistent across SW14, and each of them bears on what a survey will let you propose at a given address.
How designation changes a SW14 survey: Richmond Council maintains 72 conservation areas and three of them cover SW14 — Mortlake and The Green, East Sheen, and Sheen Common. Inside a boundary, permitted development narrows sharply: roof alterations, side extensions and cladding all fall away as article 2(3) land, which turns a £249 prior approval into a full householder submission. The householder application fee in England is £548. It also raises the standard of the drawing, because a heritage judgement is being made from your elevations.
Article 4 and your SW14 (Mortlake / East Sheen) measured building survey: Richmond Council has made no borough-wide direction, so permitted development for a measured building survey in SW14 (Mortlake / East Sheen) generally survives outside SW14 (Mortlake / East Sheen) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SW14 owner records that a measured building survey was lawful.
What SW14 (Mortlake / East Sheen) is built from: Georgian in Richmond Green and Twickenham; Edwardian villas in Barnes and East Sheen; 1930s semi-detached in Whitton; riverside cottages along the Thames. Highest conservation area coverage in London; Royal Parks and Thames corridor add heritage layers; design quality heavily scrutinised. That mix decides the measured building survey route in SW14 (Mortlake / East Sheen) more than the postcode does, and it is what a Richmond Council case officer reads first. A householder application costs £548 paid to Richmond Council direct, with 8 weeks to a decision once validated.
