In a landmark shift in urban planning policy, Sadiq Khan, the Mayor of London, has revealed plans to actively explore construction on London’s green belt, a move poised to trigger significant changes in how the city addresses its long-standing housing crisis. This step, if executed, would mark the largest transformation in housing development strategy in the UK capital since the 1960s.

The Crisis at Hand

London currently faces a massive housing shortfall, with central government targets indicating the city must build 88,000 new homes per year over the next decade. This figure dwarfs current construction levels and surpasses any historical precedent. Mayor Khan acknowledged that the existing strategy of developing only brownfield land—previously used or industrial land—is no longer sufficient to meet housing needs.

In a speech expected Friday, Khan is set to state:

“The current approach will not be enough to meet our needs.”

This signals a reversal of his earlier stance where he strongly opposed development on green belt land.

Understanding the Green Belt

Green belts, established in the UK to prevent urban sprawl, now cover vast areas surrounding cities like London. While intended to preserve natural landscapes and restrict overdevelopment, critics argue that the policy has inadvertently contributed to housing shortages, inflated home prices, and economic inefficiencies, especially in regions experiencing robust job growth.

Khan argues that public perception of the green belt as pristine and widely accessible is not entirely accurate.

“Only around 13% of the green belt consists of parks or publicly accessible land,” Khan will say.
Much of it, he claims, is poorly maintained, inaccessible, or underutilized.

The New Vision for London

The mayor’s vision does not involve unchecked development. Instead, he intends to focus construction efforts on less ecologically sensitive areas of the green belt, especially those near transport hubs, thus ensuring sustainability and connectivity.

To balance urban development with environmental responsibility, the plan includes promises to:

• Enhance biodiversity

• Create accessible public green spaces

• Maintain ecological buffers

Khan stated that these changes are critical if the city is to meet its obligations to provide secure homes for current and future generations.

Political and Public Response

Khan’s initiative has garnered support from national Labour Party leadership, including Deputy Prime Minister Angela Rayner. She emphasized that:

“Khan has our backing to deliver the housing this city needs, in line with our ambition nationally to unlock the dream of a secure home for a generation.”

However, environmental campaigners and local preservation groups are expected to fiercely oppose the move, citing risks of losing natural habitats and irreversible ecological damage. These voices may play a critical role during the public consultation period.

Timeline for Implementation

The plan’s development is tied to the London Plan—a strategic document that lays out how the capital will evolve over the next 20–25 years. Key dates include:

• Public Consultation: Open until 22 June 2025

• Draft Plan Publication: Expected in 2026

• Formal Adoption: Projected for 2028

The consultation will gather public opinion on which areas of the green belt might be suitable for release, alongside considerations around infrastructure, transportation, and local community impact.

A Balancing Act

This strategy illustrates the difficult balancing act between economic necessity and environmental preservation. With the Labour government prioritizing infrastructure and economic growth, there is a broader political push to accelerate housebuilding, even if it challenges entrenched urban planning norms.

By opening the green belt to limited, strategic development, Khan aims to reframe the green belt not as untouchable land, but as an asset to be managed—improving quality, usability, and relevance to modern urban needs.

He seeks to:

• Reclassify underused land for responsible development

• Preserve genuinely valuable ecosystems

• Deliver housing stock to meet London’s explosive demand

Economic and Social Implications

The implications of this plan are multi-dimensional. If successful, it could:

• Relieve pressure on housing prices, making the city more affordable

• Encourage investment in new infrastructure

• Support job creation in construction and related sectors

• Improve access to green spaces for underserved communities

However, opponents worry that once green belt development is normalized, future projects might push deeper into protected land, setting dangerous precedents.

Final Outlook

This proposed policy by Sadiq Khan is not just about bricks and mortar; it reflects a philosophical shift in how London envisions its growth. By challenging historical orthodoxy, the mayor is betting on a new model of sustainable urbanism—one that navigates the tension between preservation and progress.

The success or failure of this initiative will likely set a blueprint for other cities across the UK and globally, where similar housing and development pressures are mounting.

With a public consultation now underway, Londoners will have their say on how the city balances its past with its future.
