Data source
Ordnance Survey: National Geographic Database (buildings, land and sites)
Building footprints, heights and form; land parcels with their land use and built coverage; the residential and commercial unit mix of each building.

Role
What Ordnance Survey data lets a tool answer
The physical layer. Plot utilisation, mixed-use buildings, roof screening for solar, built-stock profiles and the map density layers are all read from it, and the land parcels are what sourcing searches when the question is about land rather than units.

- Used under licence from Ordnance Survey. Responses that carry NGD-derived records are priced as licensed data.
- Refresh
- Periodic full reloads; each record carries its source and load in the provenance block of a full property record.

This page describes how MarketCode uses the data. It is not legal advice on how you may reuse what a tool returns; the tool pages say when a response carries licensed records.
Tools
Tools that read Ordnance Survey records
Physical form of buildings
building_physical()Physical form of the buildings a set of UPRNs sit in: height, volume, footprint area, floor count, construction and roof material, basement, green roof, solar panels, and the residential/commercial unit mix.
Built-stock profile of an area
area_stock_profile()Composition of the built stock in an area: unit counts, HMO share, mixed-use share, median building height and footprint, solar penetration.
Plot utilisation of land parcels
plot_utilisation()Land parcels by size and how much of them is built on. Set `max_built_coverage` to 0.2 to find largely undeveloped plots.
Mixed-use buildings in an area
mixed_use_buildings()Buildings holding BOTH residential and commercial units — the conversion and permitted-development cohort.
Solar potential of roofs
solar_potential()Roof characteristics for solar screening: footprint area, roof shape and material, building height, and whether panels are already present.
Hex-binned density for maps
h3_density()Hex-binned stock and transaction density for map layers, at H3 resolution 8.
Search land or units by criteria
sourcing_search()Find land parcels or residential units matching investment criteria — the sourcing tool. Give a `location` (place or area name) or a `bbox`.
Full property record
property_lookup()Full property record for a UPRN, grouped into tiers: identity, property,
Derived
Models and indices built on it
These tools do not return Ordnance Survey rows; they return a MarketCode model or index computed from them. The methodology page explains each.
Site appraisal dossier
site_appraisal()Everything known about ONE site, assembled and judged — the site dossier.
Reconcile a property across sources
property_reconcile()Cross-source feature reconciliation for a UPRN — surfaces divergence
FAQ
Questions about Ordnance Survey data
What Ordnance Survey data does MarketCode use?
+
Building footprints, heights and form; land parcels with their land use and built coverage; the residential and commercial unit mix of each building. The physical layer. Plot utilisation, mixed-use buildings, roof screening for solar, built-stock profiles and the map density layers are all read from it, and the land parcels are what sourcing searches when the question is about land rather than units.
Which tools read this dataset?
+
10 tools: Physical form of buildings, Built-stock profile of an area, Plot utilisation of land parcels, Mixed-use buildings in an area, Solar potential of roofs, Hex-binned density for maps and more. Each is available as an MCP tool and a REST endpoint at the same price.
Under what licence?
+
Used under licence from Ordnance Survey. Responses that carry NGD-derived records are priced as licensed data. This page describes how we use the data; it is not legal advice on how you may.
How often is it refreshed, and what does it cover?
+
Periodic full reloads; each record carries its source and load in the provenance block of a full property record. Coverage: Great Britain.
Is there a building footprint data UK?
+
Yes, in effect: the MarketCode tools that read Ordnance Survey are the building footprint data UK most people are looking for, reachable over REST with an API key or over MCP from Claude, ChatGPT, Codex and Cursor with a sign-in.
