Property analytics
Join valuation, EPC and tenure data to a stable building polygon.
// 01 - mastermap-ngd
OS NGD Buildings
Every building in Britain - geometry, height, age, use class and a stable OSID.
// WHAT'S IN IT
Inside the dataset
The Buildings theme of the OS National Geographic Database (NGD) gives a single, authoritative record per building polygon. Each feature carries an OSID, building height (where surveyed), a use-class code where available, and links to addresses via UPRN.
This is the modern successor to deriving buildings from MasterMap. NGD Buildings is structured for analytics, retains stable identifiers across change, and is the cleanest input to any property, asset or risk pipeline.
Key features
- 32M+ building polygons across GB
- Persistent OSIDs - change-aware referencing
- Building height where surveyed (LIDAR-derived)
- Use-class context (residential, retail, industrial, etc.)
- UPRN linkage to occupants and addresses

// FAQ
Common questions
How does NGD Buildings differ from MasterMap?
NGD is the modern OS data model - themed (Buildings, Land, Transport, Water, Structures) with stable OSIDs, attribute-rich and structured for analytics. Many MasterMap consumers are migrating onto NGD.
Are heights available everywhere?
Heights are populated where OS has surveyed buildings via LIDAR. Coverage is national but not 100% per-feature; we can scope coverage in your area of interest before licensing.
Can we link buildings to addresses?
Yes - buildings link to UPRNs (Unique Property Reference Numbers), so you can join AddressBase records and your own occupant data.
Is this delivered as an API?
Yes - we offer hosted API access, file delivery, and custom pipeline builds.
