| Where Was War Filmed? All 2026 Series Filming Locations. |
War was filmed across London and surrounding areas, with the production combining purpose-built studio sets, corporate districts, historic squares, riverside streets and private properties to create its wealthy, cut-throat legal world. Principal photography for the first season began on 8 September 2025 and wrapped in February 2026. Not every precise filming address was made public while cameras were rolling, which is hardly surprising for a production involving recognisable actors and busy London locations. Keeping some details private also helped prevent unwanted interruptions to filming.
The main production base was OMA X Film Studios in Enfield, where much of the fictional world of War was built from scratch. The North London studio provided the controlled environment needed for the rival law firms, Taylor & Byrne and Cathcarts & Sons, as well as residential interiors, boardrooms and a fully dressed courtroom.
The contrast between the two firms was particularly important, with one designed around a modern, technology-driven aesthetic while the other leaned into darker, traditional legal surroundings. Enfield therefore did a surprising amount of heavy lifting without needing to pretend every courtroom in London was suddenly available for television.
The wider Enfield area also gave the production an established North London setting around its studio base. With OMA X Film Studios acting as the central production hub, the district provided the practical backdrop for a production that needed large-scale interiors without dragging an entire cast and crew through London's traffic every time a boardroom argument had to be filmed.
The production then shifted dramatically in appearance at Canary Wharf, London's famous financial district. Its towers, glass façades and corporate streets were used to establish the enormous business world surrounding billionaire Morgan Henderson, played by Dominic West.
The location works particularly well for the series because the architecture already looks as though someone has spent an unreasonable amount of money trying to impress investors. The financial district's polished exterior helps establish the scale of Morgan's technology empire and the corporate stakes surrounding the divorce.
The Canary Wharf setting also connects War with London's modern financial identity. The area is packed with office towers, restaurants, transport links and public spaces, making it one of the city's most recognisable expressions of corporate power. For a drama about wealth, legal manoeuvring and reputational battles, the glass-and-steel surroundings are almost doing the production design for free.
Over in Westminster, Smith Square provided a very different visual language. The historic square was used for exterior sequences requiring a more formal and institutional atmosphere, helping establish the world occupied by the older generation of senior lawyers. Its architecture brings a sense of permanence that contrasts neatly with the sleek corporate landscape of Canary Wharf.
The wider Westminster setting also suits the traditional side of the show's legal establishment. While Canary Wharf represents modern money and technology, the historic architecture around Smith Square gives the series somewhere to place characters whose power comes from reputation, connections and decades of professional influence. In War, apparently even buildings have a side in the argument.
The production also used Smith Square Hall, whose exterior supplied another imposing heritage backdrop for scenes involving the established senior legal partners. The building's formal appearance helped reinforce the old-school character of the firm representing Morgan and the traditional legal culture surrounding his substantial prenuptial assets.
For viewers visiting Westminster, the surrounding streets provide plenty of additional architectural context for the series' visual style, from historic government buildings to quiet residential squares. These locations also demonstrate why London works so effectively as the backdrop for War: a few streets can shift the atmosphere from modern wealth to institutional power without requiring a journey across the country.
The cameras also reached the Southbank, where the River Thames became a more open and atmospheric setting. The riverside district was used for outdoor dialogue, transitions and walk-and-talk sequences away from the formal offices. It gave characters room to argue, strategise or simply look considerably more thoughtful while walking beside one of the world's most recognisable rivers.
The Southbank itself offers plenty of visual variety, with the Thames, bridges, cultural buildings and busy pedestrian spaces creating a distinctly London backdrop. For War, that made it useful whenever the story needed to leave its boardrooms without abandoning the city's identity. Legal battles are apparently easier to digest with a river view.
The production also used The Plant Building in Basingstoke, a distinctive architectural location with a terraced design that was adapted to represent an elite corporate property. Its appearance allowed the series to expand its corporate world beyond central London while maintaining the polished, expensive look required by the story.
Basingstoke also adds an interesting contrast to the better-known London locations. The production did not rely solely on London's most recognisable landmarks to sell the scale of the fictional business empire. Instead, it used contemporary architecture and carefully selected spaces to create the impression of an expansive corporate network.
For the series' luxury residential atmosphere, production teams used Bayswater boutique hotels, selecting specific areas of classic London hotel properties to represent the upscale lifestyle surrounding Carla Duval, played by Sienna Miller. The setting fits a character whose public image, wealth and career are all central to the story, while the classic architecture provides a different kind of luxury from Canary Wharf's glass towers.
Bayswater itself is one of London's more visually varied districts, combining elegant terraces, hotels, restaurants and residential streets. Its location also places it within easy reach of several major West End areas, making it a natural visual extension of the sophisticated London world established throughout the series.
The cameras also moved through Piccadilly and Mayfair, using atmospheric and high-angle views of the West End to reinforce Morgan's elite lifestyle. These areas are closely associated with expensive properties, luxury retail and some of London's most recognisable streets, so the production could communicate considerable wealth without having to put a giant sign saying "VERY RICH PEOPLE LIVE HERE" in the background.
The broader Mayfair and Piccadilly area provides plenty of visual continuity for the show's upper-class setting. Its streets, hotels, private clubs and historic façades allow the drama to move between personal and professional spaces while keeping the same sense of privilege hanging over the story.
Private properties across Greater London were also used for homes, secure meeting locations and the more secretive spaces connected to the two legal factions. Production agencies supplied properties in areas including Earls Court and Shenley, allowing the series to create personal environments that would have been difficult to reproduce convincingly on a conventional studio set.
Earls Court brings another distinctly London residential texture to the production, with its mixture of period architecture, apartments and busy urban streets. Meanwhile, Shenley offers a quieter suburban setting, giving the production access to a very different atmosphere when the story moves away from corporate offices and into more private territory.
The production also used Regent's Park and Regent's Canal as part of its wider London environment. The combination of greenery, water and residential architecture provides a softer visual contrast to the legal offices and skyscrapers that dominate much of the series. It is the sort of setting where characters can have a serious conversation while the scenery politely tries to make everything look less stressful.
Southwark and Lambeth were also incorporated into the show's London geography, adding streets and urban environments that helped connect the polished corporate locations with more everyday parts of the capital. Their inclusion gives War a broader sense of place rather than making the entire city look like one enormous luxury office.
The Caledonian Estate in Islington provided another residential backdrop for the production. Its architecture and surrounding streets helped expand the visual geography of the series, particularly for scenes that needed a recognisably lived-in London environment rather than another glossy corporate interior.
It is worth stressing that the published location information does not necessarily represent every single place where the cameras stopped. Productions often keep precise addresses, private properties and short-term shooting spots quiet during production, particularly when large crews, actors and equipment are involved. In the case of War, the publicly identified locations give a strong picture of the production's London footprint without necessarily revealing every doorway that appears for three seconds on screen.
The locations also make sense alongside the story. War follows the bitter legal fallout from the breakdown of Morgan Henderson and Carla Duval's marriage, with rival firms Taylor & Byrne and Cathcarts & Sons turning the divorce into an increasingly intense professional battle. The contrast between modern financial districts, traditional legal surroundings, luxury properties and private residential spaces mirrors the show's central clash between new money, established power and increasingly personal legal tactics.
My take on the locations is that War has made a smart choice by letting London provide much of the drama's personality rather than treating the city as simple decoration. Canary Wharf brings the cold corporate scale, Westminster supplies institutional weight, the Southbank adds breathing room, while Mayfair and Bayswater quietly remind viewers that this is a world where luxury is practically part of the furniture.
The studio work at OMA X Film Studios is just as important because it gives the series control over its most demanding interiors. What makes the combination interesting is the contrast: old buildings against glass towers, private homes against enormous offices, and quiet riverside scenes against the relentless pace of corporate London. It is a suitably expensive-looking setting for a story about people fighting over money, reputation and everything else that becomes complicated once lawyers get involved.
For anyone hoping to visit War filming locations, many of the publicly identified areas are accessible to visitors, although private properties and working buildings naturally have different access arrangements. The exact locations can also change as more production information becomes available. If you have watched the series, which War location would you most like to see in person? And if you recognise another filming spot that deserves to be added to the guide, share it — the London location hunt may not be finished yet.
