2025 Highlights

A Year to Remember: One Marylebone’s 2025 Highlights

As we welcome 2026, we’re taking a moment to reflect on 2025 and what has been an extraordinary year at One Marylebone. From award wins and unforgettable events to industry-defining partnerships and immersive experiences, 2025 was one of growth, creativity and collaboration. Above all, it has been a celebration of people – our team, our partners and our clients – who continue to shape One Marylebone into one of London’s most iconic event destinations.

Award-Winning Excellence

We were incredibly proud to end the year on a high with recognition at the London Venue & Catering Awards, held at the historic Old Billingsgate on Friday 14th November. In the awards’ 10th anniversary year, One Marylebone was honoured with not one, but two prestigious accolades.

We were crowned Best Venue for Gala Dinners, Awards & Weddings, and also took home Bronze for Best Venue Under 750 Attendees. These awards are a true testament to the dedication, passion and attention to detail demonstrated by our exceptional team every single day. They also reflect the trust our clients place in us to deliver exceptional weddings, celebrations and bespoke events – a responsibility we are incredibly proud to uphold.

73 Exceptional Events

In 2025 alone, One Marylebone hosted 73 events, each one unique in its vision and execution. From elegant weddings and glamorous gala dinners to bold brand activations and high-profile award ceremonies, our spaces were transformed time and time again to reflect the individuality of every client we work with.

Each event was executed with meticulous planning, seamless delivery and a shared commitment to excellence. Seeing our venue continually reimagined remains one of the most rewarding aspects of what we do. View some of our past events here.

Strengthening Our Approved Partner List

This year also marked a major milestone in our commitment to collaboration and quality with a tender opportunity for our Approved Partner List. Spanning catering, production, floristry, furniture, branding and set and scenery, this list represents the very best of the UK events industry.

In 2025, we received an incredible 450 applications, a testament to One Marylebone’s reputation as a flagship venue. After a rigorous selection process, we shortlisted 58 finalists, welcoming new partners across core services and expanding into new categories including creative décor, photo/video and entertainment.

We are thrilled to grow this trusted network, inviting outstanding suppliers to collaborate with us and ensuring every event delivered at One Marylebone is supported by industry-leading talent.

Summer House 2025: Bigger & Bolder

One of the standout moments of the year was our Summer House party, which in 2025 welcomed a brand-new concept: The Partners Edition. Designed as a celebration of creativity and collaboration, the event also served as the official introduction to our Approved Partner List – and what an introduction it was.

With 800 attendees filling the venue, Summer House transformed One Marylebone into a vibrant, immersive showcase of what’s possible when the UK’s leading suppliers come together under one roof.

The Wedding Experience: From Aisle to Afterparty

A true highlight of Summer House was The Wedding Experience, an ambitious and unforgettable activation that captured the imagination of every guest. The stunning first-floor Galleries were transformed into a fully immersive wedding journey – from ceremony to celebration – in just 25 minutes.

Produced by the powerhouse trio Bespoke Events London, Bubble Food and Lavender Green – and with entertainment supplied by Young Guns and hosted by JP Toastmaster the experience showcased how seamlessly One Marylebone can adapt to every moment of a wedding day. From aisle to afterparty, it was a masterclass in creativity, logistics and storytelling and quickly became one of the most talked-about activations of the event.

Immersive Experiences Across the Venue

Summer House 2025 was packed with unforgettable immersive moments, each space offering something completely unique.

On arrival, guests passed through an incredible immersive party and club-style entrance created by Perception Live and Coloursonic, featuring neon lighting, smoke effects and a DJ soundtrack that amped up the energy and signalled the transition into the night ahead.

Guests were then welcomed through to the Bloom, Sips & Bites Garden by One Dining, where a jaw-dropping floral entrance designed by Amie Bone Flowers set the tone for the evening. The garden came alive with immersive production by NKN, alongside drinks from Graft Wines and Mondo Beer, all kept perfectly chilled courtesy of Ice Box. Styled with Yahire Furniture, the space offered a relaxed yet elevated setting, inviting guests to gather, sip and explore.

In the Lower Vault Lounge, guests eased into the evening with cocktails in a chic lounge environment. The space was brought to life by AV specialists RG Jones alongside mixology experts Sip Social. As the night progressed, Full Circle Entertainment elevated the energy, transforming the lounge into a vibrant late-night dance floor.

Upstairs, Monaco on the Mezz delivered full James Bond-style glamour, complete with martinis from Spook, a thrilling roulette experience curated by Full Circle Entertainment, and sleek technical production by Outline AV, adding polish and impact to the space.

The Soane Hall became home to botanical theatre, as Twilight Trees transformed the space with atmospheric installations in collaboration with Eventus, Options Greathire, Cover It Up, and Focus Productions, creating a dramatic and immersive environment. Also taking centre stage was The Drunken Jockeys, who launched their latest concept, Siena – more than a bar, but a full sensory experience. At the north end of the hall, The Altar Bar, designed alongside Invisible Blue, created a striking focal point, complete with live entertainment from Euphonica, performing on a floating platform above, while Megabooth added an interactive photo moment to the experience.

Outside, the venue made a bold statement as Bubblegum Balloons and Ficklestix adorned the exterior with a seriously Instagram-worthy installation, while inside, Bloomologie transformed The Vaults’ library entrance into something truly breathtaking.

For food lovers, the experience continued with Lettice Events Canapé Club, serving refined bite-sized creations, alongside Rocket’s Dessert Bar, delivering a playful and indulgent sweet touch. This area was elevated further by Illusion DC, whose production added theatrical flair and immersive impact to the culinary experience.

And for those who arrived hungry, The Tasting Mezz delivered in style, offering dishes from Mel’s Meals, Greenleaf, Chakra, Peppercorn, Clink Events, Leila Catering, and Spook – a true celebration of flavour, creativity and collaboration.

Bringing the entire experience together was the exceptional event staffing by Splendid, ensuring flawless service and seamless guest experience throughout the night.

The event was also captured beautifully by PR Films, Lucy Davenport and John Williams Photography.

Looking Ahead

As we reflect on 2025, we do so with immense pride and gratitude. Every award, every event and every collaboration has reinforced what makes One Marylebone so special: the people behind it.

We look forward to building on this momentum in 2026 – welcoming new partners, delivering even more extraordinary events, and continuing to push creative boundaries in one of London’s most iconic venues.

Here’s to another unforgettable year ahead!
