Find properties next to brownfield development sites
30,684 UK brownfield sites tracked from planning.data.gov.uk. Surface properties with land-assembly potential and planning precedent on the adjacent site, before the rest of the market spots them. Refreshed every 12 hours.
Why brownfield-adjacency is an investor edge
UK planning policy strongly favours redeveloping previously-developed (brownfield) land over greenfield. Once a council has approved a redevelopment on a brownfield site, three things happen to the adjacent properties: (1) land assembly — you may be able to combine the property plot with the adjacent brownfield to create a larger viable development; (2) planning precedent— similar applications on adjacent land become much easier to push through; (3) uplift — when the brownfield site is built out, surrounding property values typically rise. We surface every UK property within 250m of a tracked brownfield site, rank Gold (on site / within 50m), Silver (within 100m) or Bronze (within 250m), and link straight to the brownfield record on planning.data.gov.uk so you can read the actual planning history before bidding.
Land assembly opportunities
Gold-tier properties (on the brownfield site or within 50m) are the strongest land-assembly candidates — combine plots to create a larger viable development scheme that no individual lot supports alone.
Planning precedent attached
Every signal links directly to the brownfield record on planning.data.gov.uk so you can read the actual permission status, scheme type and council's historical approval pattern before making an offer.
Post-build uplift modelled
Once a brownfield scheme is permissioned and built out, surrounding property values typically rise by 8-15% in the first 12 months. Listings inside the 250m radius are flagged so you spot the spread before it's priced in.

Frequently asked questions
What is brownfield land?
Brownfield land in the UK is land that has been previously developed (industrial, commercial, residential) but is no longer in use. Planning policy strongly favours brownfield redevelopment over greenfield, so adjacent properties often benefit from established planning precedent.
Why does adjacency to a brownfield site matter for investors?
Three reasons: (1) Land assembly — you may be able to combine the property plot with the adjacent brownfield to create a larger viable development; (2) planning precedent — once a council has permissioned redevelopment on a nearby brownfield site, similar applications on adjacent land are easier to push through; (3) uplift — when the brownfield site is built out, surrounding property values typically rise.
How do I use the brownfield-adjacency signal in negotiation?
The chip surfaces a tier (Gold = on site / within 50m, Silver = within 100m, Bronze = within 250m) and links to the actual brownfield record on planning.data.gov.uk. Use the tier to filter your shortlist, then dig into the planning history of the adjacent site — permissioned brownfield next door is usually under-priced into the listing.
Where does the brownfield data come from?
The 30,684 sites are sourced from planning.data.gov.uk (the Department for Levelling Up, Housing & Communities Brownfield Land Register). The proximity scoring (count within 250m + distance to nearest within 1km) runs every 12 hours against active UK property listings.
