The land around Epsom and Leatherhead rises from the clay plains of Ewell and Stoneleigh to the open chalk of Epsom Downs and the Mole Gap at Leatherhead. The southern parts of the area are Green Belt and Surrey Hills National Landscape, and the River Mole and the Hogsmill bring flood risk to riverside sites.
We survey levels, contours, trees, boundaries and buildings, adding neighbouring heights and street elevations for planning drawings. Typical instructions include suburban infill and replacement dwellings, office-to-residential conversions, riverside sites in Leatherhead and sloping sites near the Downs.
Typical Epsom & Leatherhead topographical survey instructions
- Topographical survey of a suburban plot for two new houses with neighbouring heights
- Levels survey of riverside land in Leatherhead for a flood risk assessment
- Measured building survey of an office building for residential conversion
- Contour survey of a sloping site near Epsom Downs

Topographical Surveys in Epsom & Leatherhead | Frequently Asked Questions
Q1: How quickly can you carry out a topographical survey in Epsom or Leatherhead?
A: Epsom and Leatherhead are an easy drive from our Horsham head office, so most sites can be surveyed soon after the scope is agreed. Send a site plan or marked-up aerial with your deadline and we will confirm a date with the quote.
Q2: Can you survey an office building for conversion to flats?
A: Yes. We carry out measured building surveys with floor plans, sections and elevations, and can add a topographical survey of the car park and grounds, so your architect has everything needed for the conversion.
Q3: Do you survey for flood risk near the Mole and the Hogsmill?
A: Yes. We survey site, threshold and floor levels to Ordnance Datum, and bank and bed levels of the river where needed, for your flood risk consultant and engineer.
Q4: What does a topographical survey include?
A: A topographical survey records the levels and features of a site: spot heights and contours, buildings, walls, fences, kerbs, paths, trees, covers, street furniture and overhead lines. We can add building heights, street elevations, floor levels and a 3D surface where the design needs them.
Q5: What coordinate system will the survey be in?
A: Our surveys are tied to OS National Grid and levelled to Ordnance Datum Newlyn using GNSS, so they line up with OS mapping, other surveys and your design. We can also work to a local site grid if your project uses one.
