To ask the Secretary of State for Communities and Local Government, what estimate his Department made of the number of starter homes that could be provided on sites in commercial or industrial use that (a) were otherwise unlikely to be brought forward for residential purposes and (b) are not currently identified for residential development but which might be brought forward as a windfall element in a local authority's five year land supply when assessing the availability of land for starter homes under the proposed exceptions policy.

I refer the rt. hon Member to my answers of 12 and 16 March to his Questions 226642, 226652 and 226673.
