The OWO: Great British Brand 2023

‘Across the past six years, we’ve been working to create a new destination for the capital, and when The OWO opens later this year, the public will be able to step inside this British institution for the first time. There’s truly nothing like it – a flagship Raffles hotel and 85 branded private residences will sit alongside nine restaurants, three bars, an immersive Guerlain spa, Pillar health club, and a 620-capacity ballroom. 


‘When we opened the sales of our residences in 2020, it was with the intention of welcoming prospective buyers in London to visit in person. Across the pandemic, we had to pivot quickly and find ways to recreate experiences virtually, presenting our show residences online, via film and CGIs. A challenge, but the rare opportunity The OWO presents still shone through, testament to the building’s historical significance and beauty. The OWO now spans 760,000 sq/ ft, with an interior courtyard dividing the 120-bedroom hotel and the 85 private residences. Because of the hexagonal shape of the building, it was like a jigsaw puzzle fitting everything together, but clever planning has resulted in residences each unique in size and layout. The building’s history has informed every stage of its transformation. 

‘We worked on a book to document The OWO’s past, gathering historic photographs which gave us an understanding of the original purpose of its numerous rooms. Many women undertook amazing work here and we have ensured that certain rooms are named after these individuals. We’ve also of course given serious thought to partners we’ve brought on board and are working with British craftspeople throughout the refurbishment. An exciting collaboration is underway with the National Portrait Gallery and Frieze, with whom we’re developing the art strategy for the building. Each of our esteemed partners has played a pivotal role as we usher the landmark building into a new era.’ Shalini Hinduja (Hinduja Group) and Jenny Naylor (Head of Marketing, The OWO)
