Allowance for Windfall Housing within the Urban Footprint
Development plans must make allowance for windfall housing (development on unallocated sites) within the urban footprint to prevent excessive allocation of housing land, but greenfield windfall sites should not be included in this allowance.
Over the course of the plan period, windfall housing (see Glossary) can make up an important part of the supply of housing. In line with the objectives of the RDS, it is necessary to make allowance for this when deciding the number of sites to identify for development in the plan to prevent excessive allocation of housing land. For the purpose of making an allowance for windfall sites the assessment will be confined to within the Urban Footprint and greenfield sites will not be included and therefore no allowance should be made for greenfield windfalls.
