Building Features
The OS National Geographic Database (NGD) Building Features Collection gives you access to the most current and comprehensive buildings data captured by Ordnance Survey as a standalone collection.
Collection applications
The OS NGD Building Features Collection allows you to:
Ensure your buildings data is always completely up to date with up to daily updates.
Perform powerful analytics, underpinned by unrivalled OS accuracy.
Use enhanced change metadata to monitor and understand how the building landscape is changing.
Determine whether buildings are residential or commercial by using the Building Use, Buildings Description or Address Count attributes. Alternatively, use the cross references to NGD Address or NGD Land Use feature types.
The OS NGD Building Feature Type allows you to:
Perform easy selection and analysis of individual buildings using new building footprint geometry.
Quickly understand the Building Use (e.g. Commercial Retail) and Building Connectivity (e.g. standalone). Examples of how these attributes can be visualised are shown in the images below:
Perform easy data linkage both within and outside (to other OS NGD collections) the building collection using the provisioned cross reference tables.
Quickly identify and select buildings of interest using integrated Address Count information.
Determine the age of a building using the Building Age Period or Building Age Year attributes to determine the condition and potential maintenance costs. Identify the source of this information using the Building Age Third Party Provenance attribute.
Identify the primary construction material for a building to develop an understanding of the buildings energy performance. Identify the source of this information using the Construction Material Third Party Provenance attribute.
Check whether a building has a basement or basement flat to inform building safety standards plans or emergency response plans. Improve insurance underwriting and detect insurance fraud. Identify the source of this information using the Basement Presence Third Party Provenance attribute.
Quickly identify and select buildings of interest using the Building Description attribute. Examples of how these attributes can be visualised are shown in the images below:
The OS NGD Building Part Feature Type allows you to:
Quickly interpret building type (such as clock tower, multi-storey car park or archway) using the Description attribute value.
Create simple height models of buildings by using the embedded height attribution.
Key elements
Up to daily updates to data.
Plug and play – the data is simple and quick to implement as you don't need to pre-process it before you use it.
Rich attribution ensures the data is straightforward to navigate and query for items of interest e.g. using Building Use or Building Connectivity attribution,
Simplified attribute naming helps make names easier to understand.
Persistent unique identifiers with lifecycle information.
Height data included.
Land use classification (for example, residential accommodation) provided for Building Part Feature Type to indicate the prominent use of the site which contains the building.
Coverage

Default coordinate reference system
British National Grid (EPSG: 27700).
