Recent analysis from the countryside charity CPRE has unveiled significant insights into where England's future housing supply is likely to emerge – and the implications for existing homeowners are worth understanding.
The research reveals that brownfield land across England holds the capacity to deliver nearly 1.5 million new homes, with over half of these sites already benefiting from full or outline planning permission as of 2024. This means these developments could progress rapidly, fundamentally shaping local housing markets in the coming years.
Brownfield sites – previously developed land now available for redevelopment – typically enjoy proximity to established infrastructure. This includes public transport networks, schools, healthcare facilities, and existing amenities. From a planning perspective, this makes them considerably more straightforward to develop than greenfield locations, with shorter timelines from permission to completion.
Local authority registers show a 16% increase in brownfield sites identified as suitable for development, suggesting this resource continues to expand as town-centre premises become redundant and lower-density estates make way for more intensive housing schemes.
What's particularly relevant for existing homeowners is the regeneration potential these developments unlock. Brownfield schemes concentrated in areas of high housing demand – particularly London, the South East, the West Midlands, and the North West – often catalyse broader neighbourhood improvements. Transforming neglected sites into residential developments typically attracts both new residents and businesses, creating economic activity that can benefit surrounding properties.
This contrasts markedly with current patterns, where 46% of housing completions in 2021/22 occurred on greenfield sites, despite official policy favouring brownfield development. The Local Government Association estimates that planning permissions exist for a further 500,000 homes on greenfield land.
CPRE's advocacy for strengthening brownfield-first policies includes calls for regular register updates, focused investment through Homes England, and ambitious targets for affordable housing on ready-to-develop brownfield sites. Roger Mortlock, CPRE's chief executive, emphasises that whilst "brownfield passports are a great first step," enforcement requires "more teeth" including targets, current registers, and investment in genuinely affordable housing.
For homeowners contemplating a sale, understanding where new supply enters the market matters. Brownfield development in your locality could signal upcoming regeneration, improved infrastructure, and enhanced neighbourhood appeal – factors that influence both timing and positioning when bringing a property to market.
The concentration of brownfield capacity in urban and suburban areas means these developments will shape the competitive landscape for existing homes, making awareness of planned schemes in your area an important consideration in any sale strategy.
