When You Need a Topographical Survey in Camden
A topographical survey is required for:
- Planning permission: Camden requires accurate site plans for most applications
- New builds and replacement dwellings: accurate site data for design
- Basement excavations: levels affect drainage and structural design
- Sloping or irregular sites: levels impact access, drainage, massing
- Conservation areas: detailed site record required
- Development feasibility: identify constraints early
Most projects spend £595–£4,000 depending on complexity.

Frequently Asked Questions
Q: Does Camden require topographical surveys for planning?
Yes — Camden Council typically requires a topographical survey for new builds, basement excavations, and significant extensions.
Q: What coordinate system?
OS National Grid (EPSG:27700) with Ordnance Datum Newlyn (ODN).
Q: Can you survey occupied buildings?
Yes — laser scanners work around occupants. Minimal disruption.
Q: What contour interval do I need?
Standard is 0.25m or 0.5m. Specify your requirements when booking.
Q: How do I commission a topographical survey in Camden?
To commission a topographical survey in Camden, send a brief covering the site address, the site extent in acres or hectares, the desired contour interval (0.25 m or 0.5 m is standard for most planning and design work; 0.2 m for high-precision SuDS or drainage design), the features that need to be captured (drainage, trees, utilities, building footprints, boundaries, road levels), the coordinate system (OS National Grid EPSG:27700 with Ordnance Datum Newlyn heights), the deliverable format (DWG, PDF, or both), and the target turnaround. icelabz responds with a fixed-fee quote within 24 hours, and the on-site visit is typically scheduled within two to three weeks of instruction. For Camden sites in a conservation area or adjacent to a heritage asset, the brief should flag any access constraints imposed by the planning condition so these are reflected in the schedule. All icelabz topographical surveys in Camden are issued with a signed accuracy statement aligned with the RICS Measured Surveys of Land, Buildings and Utilities standard (3rd edition) for downstream planning, design, drainage, or building control use.
