Land Survey Barnet: Complete Guide
icelabz provides land (topographical) surveys throughout the London Borough of Barnet, from small residential plots in Finchley, Muswell Hill, and Golders Green through to larger sites in Mill Hill, Edgware, and Hendon. The work is delivered to the RICS Measured Surveys of Land, Buildings and Utilities standard and tied to the Ordnance Survey National Grid (EPSG:27700).
Why Barnet is a special case for land surveys
Barnet is the second-largest London borough by area and contains a wide range of planning contexts. For a land survey, the most common constraints are:
- Hampstead Garden Suburb and other conservation areas — Barnet has over 40 conservation areas, including parts of Hampstead Garden Suburb, Highgate, and Totteridge. Conservation-area sites typically need a survey that records the street-scene context (adjacent building ridge and eaves heights, chimney positions, and roofscape) as well as the site itself, to support a planning or Design and Access statement.
- Green Belt — significant parts of Barnet (around Mill Hill, Totteridge, and Hadley) lie within the Metropolitan Green Belt. A planning application in the Green Belt usually requires a more detailed existing-conditions drawing, including any existing outbuildings, hard standings, and changes in ground level.
- Tree Protection Orders (TPOs) and BS 5837 — Barnet has a high number of TPO trees. A land survey for a site with TPO trees typically needs to record species, trunk diameter at breast height (DBH), and crown spread, and to indicate the Root Protection Area (RPA) calculated to BS 5837:2012 (Trees in relation to design, demolition and construction).
- Article 4 directions — parts of Barnet are subject to Article 4 directions that remove permitted development rights. A planning application in these areas will usually require a more detailed survey than a standard topographical drawing.
- Sub-surface ground conditions — Barnet sits on London Clay, with localised sand and gravel deposits. While a topographical survey does not include ground investigation, the survey output often feeds into a subsequent ground investigation or foundation design, and the level data should be tied to Ordnance Datum Newlyn (ODN) so it is directly usable downstream.
The practical upshot is that a "standard" topographical survey in Barnet is rarely enough. The brief should always specify any conservation-area, TPO, green-belt, or Article 4 context, and the survey output should be planned accordingly.

What a Barnet land survey covers
A standard topographical survey in Barnet records the following elements to the RICS Measured Surveys standard:
| Element | Description | | --- | --- | | Boundary features | Walls, fences, railings, hedges (with heights where relevant) | | Ground levels | Spot heights on a regular grid plus break-lines at every change of slope | | Trees and vegetation | Species, DBH, crown spread, and indicative RPAs to BS 5837 | | Services and manholes | Surface evidence of covers, valves, and indicators | | Adjacent road levels | Highway datum and kerb levels at the site frontage | | Buildings on site | All structures, including outbuildings and garden buildings | | Street scene | For conservation-area sites: adjacent building ridge and eaves heights | | Green-belt data | Where relevant: outbuildings, hard standings, and level changes |
The output is a 2D CAD drawing in DWG and PDF, tied to the OS National Grid (EPSG:27700), with spot heights on Ordnance Datum Newlyn. For sites that will feed into a 3D design or BIM model, a point cloud or 3D Revit model can be added as a separate deliverable.
2026 cost bands (ex VAT)
Cost depends on site size, complexity, vegetation density, access, and any conservation-area, TPO, or green-belt requirements. Typical 2026 cost bands for a standard topographical survey in Barnet:
| Site Type | Cost | | --- | --- | | Small residential (under 0.1 ha) | £595–£800 | | Medium (0.1–0.5 ha) | £800–£1,200 | | Large or complex (0.5+ ha, conservation area, or TPO) | £1,200–£2,500+ | | With point cloud or Revit BIM add-on | +30–60% |
These are planning-reference figures; the final figure depends on the access, the vegetation, and any additional deliverables. icelabz provides fixed-fee quotes once the brief is confirmed.
When to commission
A land survey in Barnet is typically commissioned:
- Before a planning application — to provide the existing-conditions drawing that the architect or planning consultant needs.
- Before a design starts — to give the architect an accurate base for the new design.
- Before any construction — to confirm the building footprint against the title plan and to set out the foundations.
- For a BS 5837 tree survey — to provide the base plan that the arboriculturist works from.
- For a Green Belt or conservation-area planning application — to provide the detailed existing-conditions drawing that the planning authority requires.
