O2 Site Development

Latest News – October 2026:

Following extensive delays, the overall O2 masterplan approved by Camden Council in August remains a multi-phase, 10–15 year project that will eventually culminate in the demolition of the O2 Shopping Centre. However, the latest updates highlight significant shifts in both short-term investments and long-term planning:

1. Approved 2026 Planning Amendments (“The Reset”)
Landsec has utilized emergency housebuilding guidelines to significantly amend their proposal, which now includes:

• A Drastic Cut to Affordable Housing: Affordable housing across the 1,800-home masterplan has been slashed from the originally promised 35% down to just 20% (a reduction from 630 to 360 affordable homes). This change triggered heavy pushback from local community groups and political opposition.
• Increased Building Heights: To recoup costs, several blocks in Phase One (the former Homebase site and part of the car park) have been granted extra floors, with some towers now rising up to 17 storeys.
• Phase One Scope: This initial phase will construct 651 homes. Enabling works are tentatively projected to start in 2027, with main construction kicking off in 2028.
• Infrastructure Funding: Landsec remains committed to a £10 million contribution to finally deliver step-free access at West Hampstead Underground station.

2. Interim Upgrades to the O2 Centre
While Phase One and Phase Two stages develop, the O2 Centre building itself will remain open. To cover this period, Landsec is implementing a refurbishment program:

• Atrium Refresh: Ongoing work is introducing new staircases, plants, and relaxed public seating spaces.
• Vue Cinema Revamp: The upper-floor cinema has completed an extensive upgrade.
• Luxury Gym Takeover: Operator Third Space is set to open a wellness centre with swimming pool during 2027.
• Pop-up Padel Courts: An independent sports operator has opened 10 temporary padel tennis courts on the car park land, to remain until active home construction begins.
• Sainsbury’s: The supermarket will remain operational as a core asset for the foreseeable future.

However, the approved 17-storey building heights at the O2 Centre site have sparked significant debate regarding their visual impact on the neighboring Frognal ward.

Located directly northeast of the development, Frognal features elevated, sloping topography and sensitive heritage areas, including parts of the Fitzjohn’s/Netherhall, Redington/Frognal, and Hampstead Conservation Areas. According to planning assessments, public objections, and local community findings from the RedFrog Association, the visual impacts on views from the Frognal ward break down into three main categories:

1. Disruption of “Protected” Long-Distance Views
A primary concern for Frognal and Hampstead residents involves the obstruction of panoramic skylines due to increased heights: Historic England and local amenity groups formally warned that pushing the tallest residential towers up to 16 and 17 storeys will visually encroach upon and damage designated viewing corridors toward St Paul’s Cathedral and the City from the higher ridges of the ward. In addition, the increased massing creates a prominent high-rise backdrop where there was previously a low-slung retail footprint, permanently altering the traditional low-to-medium-rise character of North West London.

2. Visibility and Contrast from Conservation Areas
Because the Frognal ward sits on higher ground sloping down toward Finchley Road, the visual impact could be extreme:

• From Lower Frognal / Finchley Road Border: The towers will appear highly prominent. The 17-storey height creates a stark, modern contrasting mass right on the boundary of the Fitzjohn’s/Netherhall Conservation Area, which is characterized by Victorian and Edwardian domestic architecture. Local groups have described this high-density cluster as “intrusive” to the setting of these heritage assets.
• From Upper Frognal Ridge: Due to the elevated topography, the tops of the 17-storey blocks will be visible as a distinct artificial cluster jutting into the south and southwestern horizons.

3. Mitigation Efforts to Lower Visual Prominence
To secure final approval from Camden Council amidst fierce community resistance, Landsec made specific architectural compromises regarding the buildings’ rooflines in order to retain their 17 storey proposal:

• Elimination of Lift Overruns: To minimise the 17 storey heights, the developer excluded lift access from the rooftop plant areas, eliminating the need for bulky vertical boxes sticking out from the top of the roofs.
• Compressed Floor-to-Floor Heights: Ceiling heights were mathematically compressed to shave off total physical meters while keeping the high storey count.

Despite these technical mitigations, the consensus from the Draft Camden Local Plan Consultation and local civic groups is that the scale of the approved masterplan will permanently impose an intense, urban high-density aesthetic onto Frognal’s historic, village-like vistas.

The specific corridors of Arkwright Road, Frognal (the street/central avenue), and Lindfield Gardens will bear a heavy portion of the visual and structural impacts from the newly approved 17-storey heights. Because these residential streets sit directly on the rising hill northeast of the 14-acre development site, their elevated topography creates a highly sensitive relationship with the masterplan’s skyline.

1. Visual Disruption and Framing

• The “Wall” Effect: Rather than the existing established skyline or distant horizons, residents of the lower ends of Arkwright Road and Lindfield Gardens will face a prominent vertical “wall” of high-density housing blocks.
• Intrusion into the Domestic Setting: The extreme scaling will permanently alter the visual context of the Conservation area. Many local amenity groups (including RedFrog) campaigned aggressively against this, as the historic, domestic brick villas that define these three roads will now be juxtaposed against a dense cluster of massed blocks rising up to 17 storeys.

2. Daylight and Overshadowing Concerns

• Blocking the Sun: Because the development site sits directly southwest of these three streets, the towers will block low-angle sunlight in the late afternoons and evenings, particularly during autumn and winter.
• Loss of Direct Daylight: The shadows cast from Phase One’s towers will extend up the slopes of Lindfield Gardens and Arkwright Road earlier in the day than under previous layouts. Local independent assessments show that properties on the lower bends of these streets will experience a noticeable reduction in direct daylight, even though Camden Council’s planning review noted that “harmful overshadowing” must be managed.

3. Topographical Amplification

• Steep Grade Contrast: While the physical rooftops of the 17-storey blocks will sit lower than the top of the hill, as you travel down Arkwright Road or Lindfield Gardens, the towers will appear to “grow” in height, ultimately looming over the street-level vistas as you approach the Finchley Road boundary.

Ultimately, this localised geographical pocket—where Frognal’s quiet residential streets meet the major transit corridor—is where the tension between a high-density, visually massive £1 billion urban regeneration project and historic architectural conservation is most visible.

August 2026

As of August 2026, Camden Council has approved a major reset of Landsec’s £1 billion O2 Centre masterplan, which includes reducing the promised affordable housing quota and increasing building heights.

Local residents’ groups, including Redington Frognal Neighbourhood Forum, Redington Frognal Association, West Hampstead Gardens & Residents Association (WHGARA) and Combined Residents Associations of South Hampstead (CRASH) fought a long and hard battle against the changes, with welcome support from two local LibDem councillors, who also voted against, arguing that the reduction heavily watered down the community benefits—slashing social housing allocations and reducing the originally promised £10 million for step-free access at West Hampstead tube station. Frognall Conservative Cllr Juliette Graham not only voted in favour but was also the only councillor to raise no critical questions about the scheme.

Redington Frognal Neighbourhood Forum and Association had highlighted that the proposals were non-compliant with the National Model Design Code and would have a harmful impact on adjacent conservation areas.

Key Approved Updates and Changes:

• Affordable Housing Reduction: Camden Council has approved a reduction in affordable and social housing allocations, lowering the quota from roughly 32–35% down to about 18–20% (reducing the total count of affordable homes significantly).
• Building Heights and Scope: The masterplan adjustments allow for taller tower blocks in Phase One (up to 17 storeys) as part of the overall 1,800-home development.
• Timeline and Construction: Enabling works could potentially begin around 2027, with main construction following in 2028, which has pushed the phased completion timeline further into the future.
• O2 Centre Operations: The existing O2 Centre, car park, Sainsbury’s, and the recently upgraded Vue Finchley Road cinema will remain open for business during the phased rollout. New tenant additions—such as the Third Space gym—are still scheduled to open in 2027.
• Changes were voted on and approved on Thursday, 20 August 2026 by Camden Council’s Planning Committee. The Planning Committee passed the revised Section 73 application by a margin of 6 votes in favour to 2 against.

March 2026

As of March 2026, Landsec has submitted revised plans to reduce the affordable housing provision to 20% (approx. 360 units) from the previously agreed 35% (which would have created 630 more affordable units) saying this is in line with the government’s emergency housebuilding policy. The masterplan still aims to build 1,800 homes, new green spaces, and a new health centre.

A summary of the latest revisions and updates include:

• Affordable Housing Reduction: The developer said that economic challenges and government policy has led to the reduction of affordable housing to 20% to ensure the project’s financial viability, a move that has been criticized by local representatives.
• Main construction is due to start in 2028, with enabling works slated for 2027.
• Masterplan Scope: The 14-acre site is still intended to deliver 1,800 high-quality homes, a new community hub, and 3.7 acres of new green space, including a landscaped linear park.
• The proposal includes a £10 million step-free access provision at West Hampstead tube station.
• Sainsbury’s is exptected to stay on the site for many years, and while The Virgin Gym is set to close in Autumn a new Third Space gym is due to replace it in 2027.
• Padel courts: an application was submitted to Camden in January for 6 open air padel courts and 4 under a shared canopy on the site.

In February 2026 Camden held a Drop-In session followed by a Community Meeting and at the O2 Centre. Findings from these are now available directly from the O2 Masterplan website here: https://o2centremasterplan.commonplace.is/

June 2025

2025/0484/P
The Council agreed to use its s.203 planning powers to override access rights by the car showroom to use Blackburn Road. Statutory compensation is to be paid (based on the of difference in value of the showroom before and after access rights are removed). This is a material step intended to de-risk deliverability.

February 2025

Landsec submitted plans (2025/0484/P) to vary the conditions of the 2022/0528/P permission. These include an additional 1–2 storeys on most of the Phase 1 buildings.

December 2023

Stage 2 decision by the Mayor of London
Jules Pipe decision, 111223

November 2023

Further objections submitted, following new London Plan Guidance, including by Redington Frognal Association, Redington Frognal Neighbourhood Forum and Netherhall Neighbourhood Association:

October 2023

1. Allow the LPA’s decision to stand (be this approval or refusal). The Mayor will write a letter to the LA stating this and will have no further role in the decision.
2. Direct the LPA to refuse the application if it has been approved. The decision is announced in a letter and is binding. But this rarely happens: since 2016, the Mayor has directly refused only 10 applications.

May 2023

Letters sent by RedFrog residents and others have prompted The Planning Casework Unit to issue an Article 31 direction. This means that Camden may not grant planning permission until the Secretary of State has decided whether or not to call in the application.

The Planning Casework Unit has written as follows:

Best wishes, Keith and Nick
