Measured building survey in Westminster
A measured building survey in Westminster records the true dimensions of your property so accurate plans can be drawn from it. It is not a level 3 building report, which describes condition instead. DrawingsDirect's measured survey and floor plan work starts from £200.

Level 3 building report or measured survey: which do you need?
People searching for a level 3 building report in Westminster are usually weighing up a purchase. That report is written by a chartered surveyor and describes the condition of the structure, roof, services and defects. A measured building survey does a different job: it records lengths, heights, openings and levels, then turns them into scaled plans, sections and elevations.
If you are buying and want to know what is wrong with the building, commission the condition report from a chartered surveyor. If you already own the property, or have bought it, and want to extend, convert or alter it, the drawings come first. That is the work described on our measured building survey service page, and the plain-English version is in our guide to what a measured building survey involves.
What a measured survey gives your designer and your council
Existing floor plans, sections and elevations are the base layer for every later drawing. A planning application, a building regulations submission and a party wall notice all depend on them being right. An error of a few centimetres in the survey carries into every sheet drawn on top of it.
Where a flat or house has been altered over the years, the survey also shows what is really there rather than what an old plan says. A neighbour's wall that sits closer than expected is the sort of thing a survey finds before it becomes a dispute, and our guide to party wall agreements explains when that conversation starts.


Westminster made 366 householder decisions in the four quarters to 2026 Q2, and 49% of those were prior approvals rather than full householder applications (our analysis of MHCLG planning application statistics, table PS2).
Westminster planning in figures
Westminster made 366 householder decisions in the four quarters to 2026 Q2, and 49% of those were prior approvals rather than full householder applications (our analysis of MHCLG planning application statistics, table PS2).
Of the householder decisions in that period that were not prior approvals, 66% were made within eight weeks (our analysis of MHCLG planning application statistics, table PS2).
Across every type of development, Westminster made 4,802 planning decisions in the same four quarters, homes and everything else together (our analysis of MHCLG planning application statistics, table PS2).
For Westminster, the national register lists 56 conservation-area entries (our analysis of the MHCLG Planning Data Platform conservation-area dataset); the City Council's own conservation area map confirms whether a building sits in one. If your address is inside one, the survey should capture external details such as windows, doors and roof features in full, because the council will look at them closely. Our conservation area glossary entry sets out what changes.
Of the householder planning appeals decided in Westminster since 2021, 35% were allowed (our analysis of the Planning Inspectorate Casework Database).
Fee and next step
A Westminster survey with floor plans is priced from £200. Where your fee lands above that depends on the size and type of building; the pricing page has the full list.
To start, send the address and what you intend to do with the property through the quote form on this page. If you want to see how the same service is set out for a neighbouring borough, the Kensington and Chelsea page is a useful comparison. For the planning side, the government's guide to planning permission is the place to start.
