Open to all, the London Brownfield Sites Database is the country's most comprehensive database of land available for redevelopment. It was developed by Arup and launched by the London Development Agency (LDA) and the Homes and Communities Agency (HCA) in October 2009. 

The Database records around 2,300 previously developed "brownfield" sites across London and uses up-to-the minute Geographic Information Systems (GIS) mapping.  It includes multiple layers of information such as access to transport routes, deprivation, social infrastructure and heritage status. Visitors to the database website can find sites suitable for development, and then explore and understand a site's context.
