There is a legal requirement for Local Planning Authorities to prepare, maintain and publish registers of previously developed (brownfield) land.
Brownfield sites that meet the relevant criteria must be entered in Part 1 of brownfield land registers. Sites can optionally be entered in Part 2 of the brownfield land register, granting them Permission in Principle.
Part 1 of the register currently (December 2019) contains 63 sites, including a mix of housing allocations and sites with planning permission. Most sites fall below the threshold of 0.25ha, but are deemed capable of sustaining at least 5 dwellings.
There are no sites proposed for Part 2 of the Newham Brownfield Register.
