Soane Hall and Galleries at One Marylebone

The combined hire of Soane Hall and Galleries at One Marylebone brings together two spaces that couldn’t look more different — and that contrast is the point. The ground-floor Soane Hall is the Grade I-listed deconsecrated church: 27-foot ceilings, mosaics, stained glass, and the original altar by Sir John Soane. The first-floor Galleries are a U-shaped suite of contemporary rooms — East, West, and South — with floor-to-ceiling windows, white walls, wooden floors, and natural daylight. Together, they create a two-act event experience for 750 standing or 300 seated.

The Two-Act Event at One Marylebone

The natural flow runs reception drinks in the bright, pared-back Galleries before guests descend to the dramatic heritage grandeur of Soane Hall for the main event. The shift in atmosphere is immediate and theatrical — from light and contemporary to ornate and awe-inspiring — and guests feel it. This architectural storytelling is the combined hire’s defining advantage over venues that offer one consistent register throughout. The Galleries hold 350 standing, 150 dining, or 170 theatre independently. Floor-to-ceiling windows in the East and West Galleries flood the space with natural light, making them effective for daytime receptions, fashion show runways, exhibition displays, and corporate presentations where visual clarity matters. The contemporary aesthetic — wooden floors, white walls — functions as a brandable canvas. A pop-up bar installs within the space for drinks receptions. Soane Hall provides the grandeur. Crystal chandeliers, gilt mirrors, opulent mosaics, and 27-foot ceilings create immediate visual impact. The original altar and organ remain intact, giving events a ceremonial weight that themed decoration cannot manufacture. Light projections against the architecture amplify the drama for events wanting maximum spectacle.

Events Across One Marylebone’s Soane Hall and Galleries

Large-scale weddings use the Galleries for ceremony and reception drinks, then move to Soane Hall for the wedding breakfast and evening celebration — 300 seated in a setting where every photograph captures genuine architectural distinction. Major corporate events and conferences run 350 theatre in the Hall with the Galleries serving as breakout, registration, or pre-event networking space. Fashion shows and brand launches split between the Galleries for runway or display and the Hall for guest reception — or reverse the layout depending on creative direction. Awards ceremonies and gala dinners seat 300 across Soane Hall with reception drinks flowing through the Galleries above. Large Christmas parties take up to 750 standing across both spaces, the architectural contrast giving guests different environments to explore across the evening. The combined hire suits events that need scale, flow, and the kind of spatial variety that single-room venues cannot offer.

Extending Beyond Soane Hall and Galleries

The Vaults — directly underground, 300 standing, d&b audiotechnik sound system, licensed until 3am — serve as the after-party space that extends the evening’s arc. God’s Garden on the west side (80–200 guests, own bar and stage area, partially open-air) adds an outdoor element for summer events. The nine individually designed Greenhouses on the east side provide intimate private dining for up to 22 per greenhouse. The full venue combination creates a multi-chapter event across four distinct environments within a single building. Production is included in the combined hire — lighting, security, and cleaning come as standard. One Dining provides in-house catering, with approved external caterers also accepted and dry hire available. The alcohol licence runs until 2am with extensions. Kitchen hire is available for events bringing external catering alongside or instead of One Dining’s service. One Marylebone stands on its own island opposite Great Portland Street tube station, with mainline connections at King’s Cross, Euston, and Paddington all within a 10-minute taxi ride. The NCP car park nearby holds 200 vehicles. For events requiring 750-capacity prestige architecture with genuine spatial variety, Soane Hall and Galleries at One Marylebone deliver a combination that very few London venues can match — heritage and contemporary, intimate and grand, within the same booking.
