Check at a selected point
Point-only, partial England coverage. Tap the map first. Point checks are separate from manual whole-polygon designation intersections (available after loading an official outline); neither verifies highways.
Requires new data coverage or licences
Amber = published brownfield, purple = indicative freehold index, red = user-selected DRAFT red-line boundary. No automatic planning red line or legal title is verified.
MapTiler imagery is prepared but disabled pending an approved account, licence and spending limit. A commercial beta needs a permitted plan and origin-restricted key; the street map remains the free default.
MapTiler's Free plan is for testing and non-commercial use. A commercial beta needs an eligible plan; no account upgrades or charges happen here.
Red line = user-created draft site area, NOT an official planning application red line, surveyed title or legal boundary. Draw 3+ points and Finish.
HISTORICAL LAND-USE RESEARCH
Explore the site's past
Compare older Ordnance Survey mapping with today's geography. Historic mills, gasworks, tracks, ponds and buildings are clues to verify, not proof of contamination, ownership or legal access.
Tap a site or map point to open historic viewers near its location.
Links open original library viewers in a separate tab; SiteFound does not download, copy or embed historic map tiles. Select an available 25-inch or six-inch edition in the viewer and check its actual survey date and sheet. The Charles Close Sheetfinder has its own location search.
