About us


Built in 1826 on its own ‘island’ in the heart of the capital, our flagship ONE MARYLEBONE location opened its doors as an events space in 2008 and quickly rose to become one of the leading venues of London.

Beautifully refurbished to the original grand designs of Sir John Soane, our Grade-One listed heritage venue boasts several exclusively hireable spaces including a magnificent triple height ground floor function room, first floor double height galleries streaming with natural light, a landscaped garden with Victorian greenhouses and a private club space in the vaults under the church, all moments from Regents Park.

The grandeur of One Marylebone has attracted clients from all backgrounds – from blue-chip brands to private individuals and the Arts. Our flexible spaces offer endless possibilities to host a huge range of events from corporate & charity events, exhibitions, and film premiers to weddings, fashion shows and Christmas parties.

Whatever the event and whatever your style, ONE EVENTS can offer you something spectacular. From standing parties with up to 750 guests, to intimate weddings, and even small private dinner parties for as few as 20 people.

Our amazing ONE EVENTS Team strives to give each occasion a unique feel to impress clients and friends.
