Draft London Plan Imposes Highest Housing Target on Barnet 2026

Key Points:

• Housing Target Surge: Mayor of London Sadiq Khan’s draft London Plan (effective 2028–2038) imposes a 38% increase on the Borough of Barnet’s housing targets, assigning it the highest target in Greater London at 32,730 new units over ten years (3,273 per year).
• Green Belt Development: The draft plan earmarks 7,000 homes to be constructed on Barnet’s Green Belt, designating areas including Mill Hill and Chipping Barnet as “Green Belt Broad Locations for Growth”.
• Density and Height Rules: Small sites face minimum optimization rules (3–4 storeys typical), and the baseline for a “tall building” rises from 6 to 10 storeys, alongside new “Midrise” categories.
• Accessibility Metric Shift: The existing Public Transport Accessibility Levels (PTAL) framework will be superseded by a new Sustainable Access Measure (SAM).
• Injustice Allegations: Conservative Councillors Josh Mastin-Lee and Shimon Ryde argue that high-performing boroughs like Barnet are being penalized to compensate for housing delivery deficits in outer boroughs like Lewisham, Greenwich, and Barking & Dagenham.
• Cross-Party & Community Response: Barnet Council’s Labour administration and Conservative opposition are forming a joint working group alongside planning officers to submit a formal response before the consultation closes in mid-October.

Barnet (North London News) August 22, 2026 — As reported by Cllr Josh Mastin-Lee and Cllr Shimon Ryde of The Barnet Post, the publication of Mayor of London Sadiq Khan’s draft London Plan (effective 2028) has sparked severe local alarm. The draft document imposes the highest housing target in the capital on the London Borough of Barnet, requiring the construction of 32,730 homes between 2028 and 2038. Critics warn that the strategic directive threatens to irreversibly transform outer-London suburban environments and carve out green space for high-density residential development.

What Are the Key Planning Reforms Proposed in the Draft London Plan?

According to analysis by Cllr Josh Mastin-Lee and Cllr Shimon Ryde in The Barnet Post, the incoming framework establishes structural shifts designed to maximize land density across Greater London:

• 38% Target Increase: Barnet’s 10-year housing requirement increases by 38% over the 2021–2031 baseline, creating an annual requirement of 3,273 new homes.
• 7,000 Homes on Green Belt: The Mayor’s strategy mandates that approximately 7,000 of the required housing units be delivered on designated Green Belt land.
• Broad Locations for Growth: Mill Hill and Chipping Barnet have been formally allocated as “Green Belt Broad Locations for Growth,” making local green spaces accessible to developers.
• Mandatory Small Site Optimization: Small development sites across the borough will be bound by density targets requiring typical heights of 3 to 4 storeys.
• Redefinition of Building Heights: The threshold defining a “tall building” increases from 6 to 10 storeys, alongside the introduction of high-density “Midrise” categories.
• Adoption of SAM: The legacy Public Transport Accessibility Levels (PTAL)—which previously limited high-density developments in areas far from transport hubs—is set to be replaced by the Sustainable Access Measure (SAM).

As stated by Cllr Shimon Ryde in a press statement picked up by the Barnet Conservatives,

“Barnet residents are increasingly asking what the point of local planning is when decisions are being dictated from Whitehall and City Hall. First the Government sets ever higher targets, then the Mayor signs off on them, and Barnet is left to pick up the pieces”.

Why Are Local Representatives Calling the Target Allocation an “Injustice”?

Writing for The Barnet Post, Cllr Josh Mastin-Lee and Cllr Shimon Ryde argue that the distribution of housing allocations penalizes compliant local authorities.

Under the 2021 London Plan framework, Barnet delivered substantial housing stock via major brownfield regeneration initiatives in Brent Cross, Colindale, and West Hendon. Conversely, underperforming London boroughs have seen their housing targets reduced or maintained:

As reported by The Barnet Post, Mastin-Lee and Ryde stated that:

“Instead of marshalling underperforming London boroughs to do their bit, the mayor has instead dumped the unmet targets on Barnet. No good deed goes unpunished”.

They further compared the situation to George Orwell’s Animal Farm, asserting that

“London’s suburbs must be treated as partners in his plan, rather than its workhorse. Barnet must not be ‘Boxer’ in Sadiq Khan’s Animal Farm”.

How Are Barnet Council and Local Residents Responding?

As reported on the official Barnet Council News Portal, standard leadership has stressed the need for national financial backing. Cllr Ross Houston, Deputy Leader and Cabinet Member for Homes and Regeneration, stated:

“We are committed to building the homes residents need, including genuinely affordable homes… However, even achieving our current target has been challenging, given the years of austerity and the council’s financial position. We want to play our part in achieving responsible growth which takes the community with us, but to do this we will need significant government investment to help unlock the necessary infrastructure”.

To manage the strategic challenge, Conservative and Labour councillors in Barnet are forming a joint working group alongside local planning officers to formulate a unified response before the public consultation closes in mid-October. Additionally, representatives are formally requesting that City Hall extend the consultation window to accommodate the summer recess and the Jewish High Holy Days.

Background of the Development

The London Plan serves as the overarching spatial development strategy for Greater London, setting out an economic, environmental, transport, and social framework for the capital’s local authorities over a 10-year horizon.

In recent years, acute housing shortages across Greater London have intensified political pressure on City Hall to increase overall delivery rates. While inner-city brownfield parcels have absorbed urban density over the last decade, land availability in centrally located industrial zones has steadily diminished.

As detailed by planning reviews in Building Design and analysis from Urbanist Architecture, the draft London Plan shifts away from a “brownfield-only” paradigm. By identifying strategic “Broad Locations for Growth” inside outer-borough Green Belts, City Hall aims to unlock peripheral suburban land adjacent to existing transport networks to achieve broader municipal housing targets.

Prediction: How Will This Development Affect Barnet Residents and Property Owners?

If adopted in its current iteration without major revisions, the draft London Plan will significantly alter the socio-economic and structural environment for residents in Barnet:

• Suburban Character & Density Shifts: Residents can expect a transition away from traditional single-family detached and semi-detached developments. Planning applications will lean heavily toward multi-family apartment blocks and 1- to 2-bedroom flats, accelerating the densification of low-rise suburban corridors.
• Pressure on Infrastructure: Without immediate, dedicated capital expenditure from central government or City Hall, local public services—including healthcare clinics, schools, municipal water systems, and transport networks—risk severe capacity strain under a projected population increase of nearly 25%.
• Erosion of Green Belt Boundaries: Landowners and residents situated near Chipping Barnet, Arkley, and Mill Hill will see increased speculative planning applications from commercial housebuilders as designated Green Belt protections are relaxed under “Broad Locations for Growth” provisions.
