There are currently over 3,000 brownfields in the Brownfield Land Register
led by the Greater London Authority, their summarised area being over 2,800 hectares. The majority of them are not large (the mean brownfield area in London is under 1 ha).
IAT© data can help in the process of choosing a brownfield for development. We analysed the brownfield locations, area and the infrastructure provision level around them. Further from the centre, brownfield areas are larger, and there are also more of them. There are 1,303 brownfields in Inner London with a mean area of 0.72 ha and 1,712 in Outer London with a mean area of 1.1 ha. Almost a third of the total brownfield area is located in three boroughs - Barnet, Barking and Dagenham, and Wandsworth.
The highest IAT© values around brownfields are located in Inner London; the mean brownfield index in Inner London is 47 while the mean brownfield index in Outer London is 32, corresponding with the overall IAT© distribution.
Through our research, we can compare different brownfields, identify their challenges and benefits in terms of different infrastructure types, clarify the requirements for development and choose the best options for specific conditions.
