What Is a Combined Measured Building and Topographical Survey?
A combined measured building and topographical survey captures both the building's internal and external dimensions and the surrounding land features in one visit, producing one unified dataset. One surveyor team, one site visit, one coordinated CAD/BIM dataset — no inconsistencies between separate surveys.
What It Covers
| Component | What It Measures | | --- | --- | | Measured Building Survey | Internal floor plans, elevations, ceiling/roof plans, cross-sections, door/window positions, floor levels, structural elements | | Topographical Survey | Ground levels, contours, boundaries, trees, drainage, street furniture, utilities, adjacent buildings, site features |
Typical Costs in London (2025)
| Property Type | Combined Survey Cost (ex VAT) | | --- | --- | | Small residential (e.g., 350m² house) | £1,600–£2,200 | | Basic measured building only | From £495–£800 | | Topographical only (small site) | £800–£1,100 | | Large commercial sites | £5,000–£50,000+ |
Pricing depends on: property size (GIA), complexity, number of floors, required deliverables (2D CAD vs 3D BIM), site access, and occupancy.
Deliverables
- 2D AutoCAD drawings (DWG + PDF) at 1:50 or 1:100 scale
- Floor plans (each level), roof plans, ceiling plans
- External elevations (all façades)
- Cross-sections (floor-to-ceiling heights, stair profiles)
- Topographic site plan with contours, boundaries, drainage, trees
- 3D point cloud data (.RCP)
- Optional: 3D BIM/Revit models (LOD 200–400)
Delivery time: typically 3–5 working days after the site visit.
London Coverage
We cover all 32 London boroughs including Westminster, Camden, Islington, Kensington & Chelsea, City, Southwark, Lambeth, Hackney, Hammersmith & Fulham, Wandsworth, Barnet, Croydon, Ealing, Brent, Bromley, Greenwich, Hillingdon, and more.

Frequently Asked Questions
Q: What's the advantage of combining both surveys?
One mobilisation covers both building and site — saving 10–20% versus ordering separately, and eliminating inconsistencies between separate survey teams.
Q: What format are the deliverables?
2D AutoCAD (DWG) and PDF as standard. Point cloud data and Revit/BIM models available on request.
Q: How long does it take?
On-site: 1–2 days. Office processing: 3–5 working days. Total: typically 5–10 working days from instruction to delivery.
