Accountancy and business advisory firm BDO has taken 220,000 sq ft at The M Building on Marylebone Lane in London’s West End for its new UK HQ.
The building, which was formerly a Debenhams department store, is owned and is being developed by Ramsbury in partnership with development advisers Capital Real Estate Partners.
The M Building will provide almost 280,000 sq ft of new workspace with more than 13,000 sq ft of landscaped terracing. Following the letting to BDO, there is 58,000 sq ft of workspace available across the top three floors of the building.
BDO has had a HQ in the West End for more than a century and has been located at 55 Baker Street since 2007. It will relocate to its new home in autumn 2027.
Paul Eagland, managing partner at BDO, said: “It’s exciting to have secured such a great building, which helps us meet many of our commitments: to our people, to our clients, the West End of London, and to our planet. Working together is what powers our business, and we remain committed to offering flexible, modern spaces where we can learn together, share ideas and collectively deliver work to our clients. We have a strong attachment to the West End and our new UK headquarters will provide a modern, flexible working space in the beating heart of the regenerated Oxford Street area.
“It marks the start of a new chapter in BDO’s history and gives us a new home from which to grow our UK business in a responsible and sustainable way.”
Lars Drangel and Ola Nilsson from Ramsbury added: “It is very exciting to be able to welcome BDO to The M Building and we are looking forward to building a long-term relationship with the team there as we work together to develop a new headquarters they can be justifiably very proud of and that helps them achieve their own ambitions as a business. We are honoured that BDO has placed its trust in Ramsbury to deliver one of the most prestigious and sustainable buildings in London.”
