Measured Building Survey UK Guide
If you’re planning on buying a commercial property, planning particular renovations or require accurate floor plans, you might have been recommended a measured building survey. But what really are they, and do you really need one?
Quick answer overview:
- A measured building survey records exact dimensions and layout
- It produces floor plans, elevations, and drawings
- It does not assess conditions or defects
- Commonly used for renovations, design, and commercial property
- Costs typically range from £400 to £3,000+
Explaining measured building surveys
If you’re wondering what a measured building survey is, it’s a detailed, highly accurate survey that records and maps the exact dimensions and layout of a building, typically carried out by professionals in accordance with standards set by the Royal Institution of Chartered Surveyors.
At the end of the survey, it typically produces precise drawings like:
- Floor plans
- Elevations (external views)
- Cross-sections
- 3D models (in some cases)
To put it simply, this kind of building survey tells you exactly what a building looks like, right down to the millimetre.
What’s included in a measured building survey report
So, when it comes to a measured survey, it typically focuses on geometry and layout rather than property condition. See other survey types.
Typical inclusions:
- Internal room dimensions
- Wall thicknesses
- Door and window positions
- Ceiling heights
- Structural features (beams, columns)
Optional extras:
- Reflected ceiling plans
- Roof layouts
- Topographical data (if combined with land surveys)
Do not confuse a measured survey with a building survey. It does not include an assessment of structural condition, nor does it identify defects like damp or cracks. If you need this, you’ll want to get a Level 2 or Level 3 building survey.
