Finding available land to build new homes on isn’t always straightforward. We’ve updated our brownfield map to help make it easier.

One of the barriers to building homes is sourcing suitable, available, affordable land in the right areas. Looking at brownfield land is a good place to start but even then it’s not always easy to locate where it exists and where the most appropriate new sites are to suit your organisation’s development programmes.
Last year, we collated and mapped all individual brownfield registers that local authorities in England have been required to publish since 2017. But these registers change over time as old brownfield sites are redeveloped and new sites become available. We have therefore updated our map, using more recent data from updated local authority registers. By collating more than 300 updated registers, we were able to map 98% of all sites published in all available brownfield registers in England: almost 18,000 brownfield sites in total. The map summarises key information such as the number of sites and the number of potential homes that could be built on these sites.
Not only have we updated the data on our brownfield map, we have also added new features. By combining the brownfield registers with data from the land registry, we have mapped out approximate site boundaries for each individual brownfield site. This allows you to easily get a sense of the size and shape of each brownfield site as you zoom in to it.
We have also added new filter functionality. As well as being able to filter sites by planning and ownership status, it is now also possible to filter by site size in hectares and whether or not the site is deliverable. Just like last time, you can also add layers such as constituencies, combined authorities, regions and local authorities and get information about the development potential on brownfield sites within these areas.
We’re hoping that this updated map will be a useful resource for housing associations to identify new sites for building more homes but also for anyone interested in planning and housing.
