All Eyes on London

 As the capital sets its sights on delivering 30% of the government’s  1.5 million new homes, the Mayor of London invites you to comment on his New London Plan

Bills, bills, bills. The Planning and Infrastructure Bill has gone to the House of Lords, the Land Use Framework is currently under review post consultation and now we have GLA’s New London Plan Consultation to trawl through. One thing we know for certain (following the new NPPF at the end of last year), is that the government plans to build, build, build, and the nation’s capital is expected to  lead by example. 

But how and where does Sadiq plan to put 880,000 new homes in our already congested city? He has a plan, and he wants to know what you think. So please make your voice heard before the consultation wraps up on the 22nd June 2025. In the meantime, here is a quick overview:

London-wide Green Belt Review 
London’s Green Belt will undergo a review in which potential housing development opportunities will be identified. 

“The green belt can often be low-quality land, poorly maintained and rarely enjoyed by Londoners. Only around 13% is made up of parks and areas that the public can access,” explained Khan last month. 

There is a proposed hierarchy; brownfield first, followed by what the NPPF refers to as ‘grey belt’ – Green Belt areas that have either been previously developed or do not significantly contribute to the three golden rules of the Green Belt. Existing brownfield sites within GLA are thought to have capacity for 40,000 homes so it looks likely that the Green Belt has nowhere to hide. However, any new developments must provide affordable housing in ‘sustainable, liveable neighbourhoods with access to public and active travel options, with improved access to green space and nature.’  Large scale developments (10,000+ homes) on London's Green Belt are being considered in areas with good transport links. The success of increasing housing construction will hinge on securing funding for transport enhancements, a recurring theme throughout the consultation.

Metropolitan Open Land 
The Mayor has stipulated that the New London Plan must separate Metropolitan Open Land (MOL) from Green Belt considerations, given it a degree of protection. However, he has suggested that some golf courses should be reviewed for landscape-led redevelopment. 

The Rest 
Encouragingly the new plan suggests that smaller green areas and linear green spaces should be given more value, not just parks and open spaces. This points to a shift towards appreciating kerbside pocket public realm. This is an opportunity for new developments to really make the most of the outside spaces between the buildings that they create. 

Green Infrastructure and Biodiversity
Alongside the Local Nature Recovery Strategy (Environment Act 2021) the New London Plan proposes a London Green Infrastructure Framework. These initiatives will work in tandem to map existing green spaces and pinpoint areas where green infrastructure can be implemented to alleviate flood risk and reduce heat risk as well as opportunities for rewilding and nature restoration. The Mayor is encouraging stakeholders to share evidence and experience of using the Urban Greening Factor (UGF) in London. As Landscape Architects we certainly advocate for a cohesive approach between UGF and BNG so that there is no ambiguity and that both tools work together to enhance biodiversity across the city.

The New London Surface Water Strategy 
The New London Plan suggests that a Greenfield Runoff Rate for new developments should be introduced to ensure that rates match natural levels. The plan encourages the use of permeable surfaces on sites that are redeveloped and that people might be forced to apply for planning to change front gardens into parking spots. There is no direct mention of Sustainable Drainage Systems (SuDS). However a surface water strategy (more on this later) has been released to sit alongside the Thames Estuary Plan which focuses very heavily on nature-based SuDS. 

Challenges 
Housing delivery in London, and indeed across the country, is up against spiraling construction costs, higher interest rates and regulatory changes. In 2023/24, just 43,600 homes were approved and only 33,000 homes were completed – less than 50% of the new annual target. 

Many would argue that the real problem isn’t necessary the planning process itself but the staggering house prices each year. High density housing in London is going to receive push back from the public. Tall buildings may just become the norm along the city’s skyline. 

There are difficult choices to be made. But the new London Plan is an opportunity for the capital to set a high standard for the rest of the country. If we want the right choices made, we must comment and share our experiences in order to shape an effective, flexible, streamlined new London Plan that fosters a resilient and sustainable capital that can continue to thrive and grow without turning all green to grey.
