Measured surveys across Westminster — floor plans, elevations and sections to a 3mm tolerance. Captured on a Leica Disto and a BLK360 point-cloud scanner, drawn up in Revit or AutoCAD, by MCIAT chartered technologists.
Measured building survey in Westminster, a borough of Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density, are the full measured-survey-to-submission drawing set City of Westminster needs in order to determine an application: existing and proposed plans, elevations and sections at 1:100 and 1:50, a location and site plan, and the supporting statements the case officer asks for.

Measured surveys across Westminster — floor plans, elevations and sections to ±3mm accuracy. Leica Disto laser + BLK360 point-cloud scanning, AutoCAD and Revit deliverables, MCIAT chartered.
Housing stock in Westminster: Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density.
Character: Heritage-first planning approach; listed buildings on almost every street; basement and rear extension policies particularly strict.
Article 4: Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones.
Basement policy: a single storey is the limit here, generally covering under half the rear garden footprint, and inside a conservation area the lightwells and rooflights that serve it are controlled tightly on top of that. Heritage casework dominates the workload. Across three years of returns ending in March 2026 the council decided 4,689 listed building consents to alter or extend, granting 4,322 — more than a third of everything of that kind decided in London.
A chartered technologist arrives at the Westminster address with laser and scanner in hand. A mansion-block flat is often done in ninety minutes; a stucco terrace over four floors is emphatically not.
Drawings are issued from Revit or AutoCAD at 1:50 or 1:100, worked to a 3mm tolerance, and every room, opening, fitting and pipe run is labelled on them.
Four elevations and cross-sections. One set feeds the planning application, the structural design and any award under the Party Wall Act, and all three come unstuck if the set disagrees with itself.
A point cloud from the BLK360 stays with the file, and on Westminster buildings it is frequently the only honest record anyone holds. Listed facades, cornices, curved stair walls, ceiling heights that change floor by floor: 44.1% of the 132,190 dwellings in this city are pre-1900 (VOA CTSOP4.1, 31 March 2025), and almost none of them are square.
Delivered as DWG, RVT, PDF and IFC, so that your architect, your structural engineer and your contractor work from one model instead of three interpretations of it.
Accuracy is reported to RICS standard, 3mm point-to-point and 5mm absolute. That is the standard against which Westminster City Council, an insurer, or a party wall surveyor will sign the drawings off.

Single planning or regs submission.
Planning + building regs + structural.

| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|---|---|---|
| W1W | Fitzrovia / Great Portland Street | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | A measured building survey at an W1W address in Fitzrovia / Great Portland Street is determined by Westminster City Council under its own Local Plan policies for Fitzrovia / Great Portland Street. |
| W2 | Bayswater / Paddington | Victorian stucco terraces | A measured building survey at an W2 address in Bayswater / Paddington is determined by Westminster City Council under its own Local Plan policies for Bayswater / Paddington. |
| W9 | Maida Vale | Victorian terraces, mansion blocks | W9 is Maida Vale, wholly inside Westminster. The city council handles the measured building survey, and Maida Vale case officers read each address against the W9 conservation-area map. |
| WC2B | Covent Garden / Holborn | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | Covent Garden / Holborn is split at WC2B. Either Westminster City Council or Camden Council can determine a measured building survey here, so the WC2B address is checked against both policies maps first. |
| WC2E | Covent Garden | Georgian terraces, conversions | Covent Garden sits wholly inside WC2E, so Westminster City Council validates every measured building survey submitted from an WC2E address. |
| WC2H | Covent Garden / Leicester Square | Georgian terraces, conversions | WC2H covers Covent Garden / Leicester Square only; Westminster City Council handles the measured building survey, and Covent Garden / Leicester Square case officers apply the WC2H conservation-area map. |
| WC2N | Charing Cross / Strand | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | A measured building survey at an WC2N address in Charing Cross / Strand is determined by Westminster City Council under its own Local Plan policies for Charing Cross / Strand. |
| WC2R | Strand | Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density | Strand sits wholly inside WC2R, so Westminster City Council validates every measured building survey submitted from an WC2R address. |
Move a street in Westminster and the floor-to-ceiling height, the wall build-up and the plan depth all change with you. All three govern what a survey can support at a given address.
How designation changes a Westminster measured building survey: Westminster City Council maintains 56 conservation areas, including Covent Garden, St John's Wood, Mayfair. Inside any of them a Westminster measured building survey cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Belgravia sets the tone for Westminster casework.
Westminster and Article 4: Multiple Article 4 Directions — office-to-residential restrictions, HMO conversions, retail to residential in shopping zones. A measured building survey planned at a NW8 address is checked against that direction first; Westminster City Council publishes the Westminster extent, and the NW8 line rarely follows the Westminster boundary you would expect.
Westminster below-ground policy: Westminster basement policy restricts to single-storey, typically under 50% of rear garden footprint; lightwells and rooflights strictly controlled in conservation areas. Any measured building survey in Westminster that goes below existing foundations triggers two months notice under section 6 of the Party Wall etc. Act 1996, and Westminster City Council will want the NW8 ground and groundwater position set out.
What Westminster is built from: Grand Georgian and Regency terraces in Belgravia and Pimlico; Victorian and Edwardian mansion blocks; heritage-rich townhouses throughout; very high listed building density. Heritage-first planning approach; listed buildings on almost every street; basement and rear extension policies particularly strict. That mix decides the measured building survey route in Westminster more than the postcode does, and it is what a Westminster City Council case officer reads first. A householder application costs £548 paid to Westminster City Council direct, with 8 weeks to a decision once validated.

Straight answers to what Westminster owners and lessees ask us about measured surveys.
Start a free quote →Survey fees in Westminster track size and complexity. A two-bed flat is the baseline; a three or four-bed maisonette, or a whole-house conversion, steps up from it; large and listed properties are quoted individually. Plans, elevations and sections come inside every quote. There is no hourly billing at any stage. See our fees.
Time on site in Westminster is typically 60 to 120 minutes according to the property. CAD drawings follow within five working days, with a 48-hour turnaround available at a small premium.
A Leica Disto X3 and a BLK360 scanner between them give 3mm point-to-point accuracy. The output is RICS-compliant, and it is accepted by Westminster City Council planning officers, by Building Control, and by the structural engineers and party wall surveyors working across the city.
Yes — Westminster's grand Georgian and Regency terraces in Belgravia and Pimlico period stock is our core work. We survey listed buildings, conservation area properties and complex geometries using BLK360 point-cloud scanning. The 3D scan captures every architectural detail for heritage statements and planning applications.
You get AutoCAD .dwg, Revit .rvt, PDF and IFC. Floor plans, elevations and sections, plus the 3D point cloud wherever the property was scanned. Everything annotated, and ready either for your own consultant team or for a submission to Westminster City Council.
Yes — flats, maisonettes, HMOs and conversions across all Westminster postcodes (SW1, W1, W2, W9, NW1, NW8, WC2). We handle communal areas, staircases and party walls between dwellings — essential for flat conversion planning applications or lease drawings.
Yes, and in Westminster the reason is the calendar. Every application here needs accurate existing drawings, and Westminster City Council validation officers throw out submissions in which the existing plans and the proposed scheme refuse to reconcile. What makes that expensive in this particular borough is how long a second attempt takes. Of 728 householder decisions measured against the statutory period, 542 were issued inside eight weeks — 74.5%, where the 33 boroughs pooled reach 92.5%. Nor is the council buying that time by agreement: it granted an extension of time on 3,819 of 14,408 decisions, 26.5%, which is below the 34.5% London figure. Cases here simply run long, without anybody having negotiated for the extra weeks. A survey that is right first time is the cheapest fortnight you will ever buy, and the same drawings carry straight through into the building regulations application afterwards.
We cover all Westminster postcodes — SW1, W1, W2, W9, NW1, NW8, WC2 — and adjacent boroughs. Survey appointments within 3 working days, no travel charges within Greater London.
