From Monday 29 February, BMB will be based in The Crane Building in Lavington Street. The agency has been based in Covent Garden for ten years.
BMB was launched in 2005 as an independent agency by Trevor Beattie, Andrew McGuinness and Bil Bungay.
In December 2008 BMB sold a 49 per cent of the business to Cheil Worldwide, which later increased its stake to 75 per cent.
Last year Cheil hired Paul Hammersley, the former chief executive of EDC UK, as its first UK group chief executive. Hammersley has been tasked with representing Cheil's interest in BMB, as well as helping Cheil grow in the UK.
Juliet Haygarth, the chief executive of BMB, said: "We’ll be sad to say goodbye to our higgeldy piggeldy home in Covent Garden, but it's time to move on. The pain of packing up will disappear on Monday when we walk into our new space which has everything we hold dear as well as lots more room for us to think, make and create.
"While staying true to our heritage, we now have a chance to build the agency with an eye to the future.
"We’re doubling the size of our in-house production studio, integrating our designers into one space - all the stuff we’ve wanted to do for a while."
