One Marylebone

Set within a prestigious Grade I listed building next to Regent's Park, One Marylebone is one of central London's most striking event venues, where soaring architecture and natural light come together to create a setting unlike any other in the capital. Originally built in 1825 and in operation as an event space since 2008, One Marylebone has welcomed everything from brand takeovers and film premiere after-parties to fashion shows, and today stands as a byword for versatility, scale and sheer visual drama. In 2025 it was named Best Venue for Gala Dinners, Awards or Weddings, recognition of a venue that consistently delivers on both atmosphere and execution. At its heart is the Soane Hall, a breathtaking space with 27ft ceilings that can transform from either an intimate seated dinner to a 400-guest ceremony or a full-scale gala. Around it sit four further spaces, each with its own character: the elegant Galleries, ideal for drinks receptions and exhibitions; the atmospheric Vaults, a moody subterranean space across two levels; the Garden, a rare large slice of outdoor space in central London perfect for drinks receptions, summer parties or ceremony; and the Greenhouses, a striking intimate private dining venue. Because these spaces connect, events can move fluidly from one room to the next: drinks in the Garden, dinner in the Soane Hall, dancing in the Vaults, all without guests ever leaving the building. One Marylebone plays host to an exceptionally broad range of events: weddings, corporate conferences, product launches, Christmas parties, private celebrations, gala dinners and awards ceremonies. Its flexibility is matched by its location: directly opposite Great Portland Street Underground station, with multiple alternative underground and mainline stations a short walking distance away. For a venue of this scale and grandeur, it is remarkably easy for guests to reach from anywhere in London or beyond. Food and drink can be provided in-house by One Dining, the venue's resident catering team, who can design menus around each event; from formal plated dinners and roaming canapés to interactive food stations and full cocktail programmes. Clients who prefer a different style can instead choose from a curated list of approved external caterers, giving every event the flexibility to match its own brief. What sets One Marylebone apart is the combination of heritage and adaptability. Few venues in central London can offer Grade I listed architecture, a large outdoor space, multiple distinct indoor spaces and the technical infrastructure for large-scale production, all under one roof. Event organisers can dress the space to suit almost any brief, from stripped-back and contemporary to opulent and traditional, and the venue's in-house events team, along with a curated network of approved suppliers covering everything from lighting and production to florals and entertainment, is on hand to help bring that vision to life. For anyone planning an event in London that needs to feel genuinely memorable, whether that's 20 guests in The Greenhouses or 800 in the main building, One Marylebone offers a rare combination of scale, character and location.
