Written by David Williams, FRICS, Executive Director at Savills, this piece examines the scale and ambition of Old Oak Common. It sets out how infrastructure, connectivity and placemaking could shape a new district for London.

The overall opportunity at Old Oak Common targets the delivery of 25,000 homes and the creation of 56,000 new jobs and therefore represents London’s biggest brownfield opportunity¹. The scale of the district’s potential is elevated significantly by its infrastructural and locational setting, which lays the foundations for the development and placemaking to follow. 

As we move forwards into 2026, where the Labour government is expected to pass verdict on various key infrastructure schemes across the country, including some for which Old Oak Common is being designed, this paper seeks to lay out the scale of the opportunity at this new district through examining the specific plans in place for the community, assessing current and potential passenger flows, and providing a clear timeline of expected completion dates as they stand at the time of writing (albeit with the traditional caveats on delivery dates that are a prerequisite for projects of this magnitude). Ultimately, are the proposals worthy of City status and will they merit a privy charter?

But first, some background: the design, assembly and implementation of the masterplan is to be carried out by a Mayoral Development Corporation, the Old Oak and Park Royal Development Corporation (OPDC), within the boundaries of an allotted development zone² (Figure 1), which spans the boroughs of Hammersmith & Fulham, Brent, and Ealing. This is the broader area which is expected to accommodate the aforementioned 25,000 homes. At the core of this development zone sits Old Oak, the section surrounding the new station in which the majority of OPDC land assembly, placemaking and development will take place, and as such the specific location on which this article shall focus.

The scheme itself

The new district at Old Oak Common, supported by the planned infrastructure, is poised for exponential growth: it will be accessible to Euston in 10 minutes, as will be both Bond Street and Heathrow, Birmingham in 38 minutes and Bristol in 1hr 30 minutes⁵. Old Oak itself will provide 8,000 homes, 1,500 of which will be targeted in Phase 1 as the most immediate delivery priority, as well as up to 200,000 sq m of commercial and community accommodation across 70 acres - of which 30% will be public open space⁶. An illustrative Allies & Morrison masterplan framework, with the support of the OPDC board, is currently in place to set out the vision for the area. The masterplan encompasses a mixed-use scheme centred around focal points including the HS2 Station, Acton North and Old Oak Common, with a heavy focus on integrating green residential neighbourhoods to a bustling town centre via high quality public realm in this currently isolated corner of West London. Please see figure 3 below for a map of the first phase of the development. 
Headline features include the blending of a major town centre area between Old Oak Common and North Acton Stations with a pedestrianised, green residential community along an enhanced Grand Union Canal⁸. Connecting these two distinct neighbourhoods will be The Old Oak Mile and The Common Cut, broadly following the routes of the existing Victoria Road and Old Oak Common Lane respectively. The Old Oak Mile will be a tree-lined street with green pockets designed to reflect the 7 distinct characters it passes through from  North Acton to Harlesden High Street⁹. The Common Cut, meanwhile, will provide a bright, landscaped route prioritising active travel to connect the canal to Wormwood Scrubs via Old Oak Common Station¹⁰. 

Figure 3: The Initial Old Oak Common Development⁷.
There will be new public parks outside both Old Oak Common and North Acton Station (Old Oak South and Acton Wells parks respectively), with a focus on connecting North Acton on its northern flank from which it is currently isolated. The area alongside Old Oak Common’s new public realm will form the start of the predominant office and commercial location which stretches along The Old Oak Line to North Acton, enabling easy commuting, with the greener and less intensive northern areas forming a residential neighbourhood around Channel Gate Park and along the canal¹¹, as shown by the use areas map in Figure 4. 

Figure 4: The Old Oak development Area by Planned Use Allocation¹².
In total, Old Oak is set to include 8,000 new homes (including affordable), with a long-term target by 2050 of 25,500 across the wider OPDC development area, of which 50% of those on government land will be affordable¹³. This is to be supplemented by over 2 million square feet of commercial and community accommodation, the majority of which will be concentrated by the plaza alongside Old Oak Common Station¹⁴. 

In terms of the stations, Old Oak Common itself has been subject to £1.7bn of investment¹⁵, and will be the largest sub-surface station ever to be built in the UK with a public plaza twice the size of Trafalgar Square¹⁶. 

Flanking this enormous project are two more modest proposed stations, not to be funded by HS2 themselves. We shall begin with the more promising: Old Oak Common Lane Station would be located approximately 300m to the west of Old Oak Common Station, and would allow internal connections for West London commuter passengers from the Mildmay and proposed West London Orbital lines to HS2 and Elizabeth Line services into Central London¹⁷. It is deemed by Transport for London (TfL) as holding a good transport case¹⁸, but similarly to the other three proposed new West London Orbital line stations - Neasden, Harlesden and Lionel Road - is heavily dependent on government funding¹⁹. Notably, the West London Orbital line has recently seen £6.65M pooled by the OPDC, TfL, and four London Boroughs in order to further the business case²⁰, which is assisted by the line’s proposed route along existing underutilised rail links, minimising potential costs. Hythe Road, meanwhile, seems to be more problematic: whilst it is supported conceptually by the OPDC in placemaking terms, the transport case is deemed insufficient by TfL to warrant funding²¹, so our view is that its creation is unlikely. 
Having seen the scale, designs and outline plans for the development, what will be the Old Oak effect? Ultimately, beyond simply increasing connectivity and providing London access to HS2, Old Oak Common represents the chance to create the new destination for London adding resonant social value by reversing the current unemployment and child poverty trends. Specifically, unemployment in Old Oak currently sits at 7.1% compared to a 3.5% national average, whilst the Borough of Brent has 40% of its children living in poverty and 47% of citizens in social housing compared to the 24% London average²⁴. 

Figure 5: The Proposed Designs for Old Oak Common²².
This regeneration is already instilling a significant economic impetus into Old Oak, hidden in plain sight. 8,000 new homes and 11,000 new jobs - with the promise of 65,000 jobs by 2041 - will be transformational²⁵, and whilst housing is understandably the foremost delivery priority for the OPDC, this includes new educational, health, leisure and retail facilities²⁶. This process is underwritten by this exceptional confluence of new rail led infrastructure: from a real estate perspective, one needn’t look further than the sharpening of yields seen around various stations in Central London after the arrival of the Elizabeth Line to understand the potential for significant investment and development across Old Oak - a new City in the making?

Site assembly

Whilst the assembly of a site of this size and complexity is always going to be challenging in London, the Old Oak Common development benefits from substantial initial public sector and stakeholder presence in the development area. Nevertheless, the Old Oak and Park Royal Development Corporation Compulsory Purchase Order 2025 (henceforth ‘CPO’) was issued on the 12th of September 2025 and is currently awaiting ratification²⁷. The CPO will facilitate the acquisition of the remaining land in private hands on the site, standing at approximately 7% of the 31 hectares required²⁸. 

We understand that in 2019, the attempt to acquire the sizeable plots of Cargiant land to the northeast of Old Oak Common Station via CPO, a key section of the masterplan for residential development, was rejected by the Planning Inspectorate which supported Cargiant’s refusal to sell due to sudden changes in market conditions²⁹. However, Imperial, a large historic landowner which developed its first buildings in Old Oak in 2015 and owns over 17 acres in the area³⁰, have recently invested into the project: Imperial purchased Victoria Industrial Estate, east of North Acton Station, from Segro at the end of 2024 with a view to repositioning the site to provide office and lab accommodation for the upscaling of spinouts from Imperial’s alternative locations across the WestTech Corridor³¹. 
WestTech London is a major initiative from Imperial to create a world-leading hub for innovation and technological advancement, predicated on the university’s own presence in South Kensington, Paddington, White City, Old Oak and Park Royal³³. Indeed, through the repositioning of Victoria Industrial Estate, Imperial will be the anchor occupier for the commercial element of Old Oak, a significant benefit for the area as the presence of the world’s 2nd-ranked university³⁴ has the potential to influence both the outcome of the future scheme and the occupier typology through cementing the area’s status as a hub of innovation and excellence. 

This partnership with Imperial is already beginning to bear fruit with the successful recent launch of the new Grapht Works facility in the Old Oak Innovation Cluster at North Acton, providing 28 units from 100-1,700sq m to support the pilot, demo and scale-up needs of deep tech businesses and bridge the gap between R&D and full-scale commercial production³⁵.

Connections and Infrastructure

Connections and Infrastructure

As has been discussed throughout the article thus far, transport connections are key both as an initial justification for the scheme’s importance, as well as a determinant of its success in encouraging the resurgence of the existing community. The current stations in place at Old Oak the site, their key destinations, and passenger numbers are as follows:

Figure 8: A Map of Old Oak Common’s Rail Connectivity at Present – Prepared by Savills.
Figure 9: A Table of Passenger Numbers at Old Oak Common as of Most Recent Surveys to October 2025.

As both the maps and figures above show, Old Oak Common already benefits from strong passenger flows and rail connections, but via a disjointed plethora of smaller stops with limited interconnectivity and numerous challenges for passengers seeking to change between stations with a transport ‘black hole’ in the triangle between Willesden Junction, North Acton and East Acton.
The figures below show the expected layout of Old Oak Common upon expiry of the current local Plan in 2038, assuming the construction of the West London Orbital Railway. 

Figure 10: The Potential Transport Additions by 2038 (Minus Existing Infrastructure) – Prepared By Savills.
As Figures 11 and 12 show visually and statistically, even without the potential construction of Hythe Road and Old Oak Common Lane stations, Old Oak Common holds the potential to become one of London’s busiest and most accessible districts, and the largest rail conference since HS1. Old Oak Common station alone is being constructed to handle a capacity of 88.50M passengers per year⁴¹.

Figure 11: Combined Map Showing the Potential Connectivity of Old Oak Common by 2038 Including Current Infrastructure – Prepared by Savills.
Figure 12: A Table of Potential Passenger Numbers at Old Oak Common by 2038 (Assuming Existing Stations Maintain Current Levels).

Whilst it should be noted that this figure is a capacity rather than a confirmed annual volume (as the figures for the other stations listed are), it a reasonable assumption that given the scale of investment and development into the local area, as well as the importance and range of the services which the station will provide, with particular emphasis on HS2, the Elizabeth Line, and the Great Western Mainline, demand is likely to follow supply closely. If achieved in today’s climate, this figure of 88.50M would position Old Oak Common as the second most used station in the UK, ranking behind London Liverpool Street (94.50M) but notably ahead of London Paddington and Tottenham Court Road (66.90M and 64.20M respectively)⁴². 

Figure 13: A Timeline of Key Development Milestones at Old Oak Common. Created With Reference to Mayor of London & OPDC (2025a).

As shown in Figure 13, significant progress has already been made in the transformation of the area and construction of Old Oak Common station in particular, which secured planning in 2020 and has completed excavation of the 20-metre-deep underground station box to enable current work on the high-speed platforms⁴⁹. 

At present, the key process of land assembly is underway, set to be facilitated by the CPO process of which formal notice was given in September 2025⁵⁰. The complication and expense of this process, although still significant, is greatly reduced by over 90% of land required for initial redevelopment proposals being in public ownership. 

Additionally, the first meanwhile use has already begun, with OPDC’s Minerva Works scheme opening in the heart of Park Royal to house a group of local enterprises focused on the circular economy⁵¹. Specifically, Minerva Works is seeking to reuse waste materials from businesses in Park Royal and the nearby HS2 Development, including the clay extracted in the construction of Old Oak Common station, with a total aim of creating 35 jobs and salvaging 20 tonnes of otherwise wasted materials – saving 28 tonnes of carbon - over the scheme’s lifespan⁵². 

The next steps towards delivery involve negotiating a public land agreement with the Department for Transport and Network Rail following the presentation of the outline business case. Once this is completed, the OPDC can begin work on selecting a JV partner bring the long-awaited masterplan forwards.  

Key dates remaining in the delivery process include the construction of the first homes, slated to commence in 2029⁵³, the completion of Old Oak Common station in 2030, and the arrival of HS2 Phase 1 (Old Oak Common to Birmingham). The latter has been subject to review, with both Transport Secretary Heidi Alexander and HS2 Ltd CEO Mark Wild admitting that the initial 2033 deadline is now infeasible⁵⁴, precipitating a £25.3bn government funding packing for 2026-2030 in a bid to form a new business plan targeting cost limitation and certainty on timescales, which is still yet to be provided⁵⁵. Should it gain approval, The West London Orbital Railway is estimated to complete in the mid-2030s, providing commuters from across West London in areas such as Brent Cross, Brentford and Hounslow better access to the underground system, and subsequently Central London, via the Elizabeth Line from Old Oak Common⁵⁶. 

Beyond this, the HS2 station at Old Oak Common is expected to be fully operational by 2035 and when coupled together with the welcome news of the Old Oak to Euston tunnel commencing construction in January, it is anticipated that this vital link to Central London will be operational around 2040.  

Ultimately, the OPDC are leaving no stone unturned in their bid to drive this compelling regeneration forwards and ensure that Old Oak capitalises on its strategic location surrounding London’s first major new transport intersection to deliver a new community predicated on sustainability, community and innovation and opportunity for West London.
