Given the failure of the London housing market to keep pace with demand, do you agree that the assumptions in your Further Alterations to the London Plan, have over-estimated the likely number of houses that will be built in East London between now and 2025 by nearly a third? Do you regard it as realistic that the private sector has the capacity to meet these ambitious targets, or is a degree of 'smoothing' required, so that the houses are built on these sites but at a later date?

Housing targets are based on a joint borough and GLA Strategic Housing Land Availability Assessment which follows a consistent pan-London methodology. Realistic assumptions are made on the phasing and likely build out rates on large sites. This is supported by an independent viability assessment which examined areas of East London in detail, given historic viability issues and concentrations of London's housing capacity.

Historic trends in approvals suggest that the planning system should be able to bring forward this capacity but, as explained at the Examination in Public into the London Plan, trends in completions suggest that translating it into capacity will be a challenge. However, recent independent research provides a more optimistic picture in terms of starts on large sites. My Housing Zones initiative aims to accelerate house building and seven Housing Zone bids have been received in East London.

Annual average monitoring targets are set out in the London Plan. These allow some flexibility year on year, providing the overall long-term trajectory is maintained.
