Feeding the Pipeline …– looks at how many additional implementable planning permissions on sites are needed to boost housing delivery from 243,770 net additional homes (2019/20) to achieve ambitions of delivering 300,000 net additional homes per annum across England. It does this by exploring how 10 of the country’s largest housebuilders draw upon their land pipelines to bring forward new homes, illustrating how many additional planning permissions will be necessary for the housebuilding sector as a whole to scale-up their delivery to achieve the national 300,000 homes per annum ambition.
The research shows that, with generally short pipelines held by housebuilders equivalent to 3.3 years’ output and each ‘outlet’ delivering on average 45 homes each year, to bridge the gap to 300,000 net additional homes will require additional sites – or ‘outlets’ – being granted planning permission. The scale-up needed is equivalent to each District in England granting permission for an extra 4 to 5 medium sized sites per year, or alternatively 4 to 5 large sites which deliver each year over a longer period, in addition to continuing to approve its usual ambient level of permissions being granted.
