Derwent London has appointed Multiplex as main contractor on the 50 Baker Street development in Marylebone, London.
The 236,000 sq ft office-led, mixed-use scheme will comprise office space, retail units and restaurants, in addition to 17 residential apartments.
Designed by AHMM, the nine-storey development will also feature a new cultural and educational facility operated by the Baker Street Quarter Partnership. Following the completion of demolition and enabling works by McGee, main works construction will commence in 2027 with completion targeted for 2029.
Richard Baldwin, director of development at Derwent London, said: “After a one-year pre-construction services agreement, we are pleased to be working with Multiplex once again to deliver 50 Baker Street following our successful White Collar Factory and 80 Charlotte Street redevelopment projects. We are excited about the prospects for 50 Baker Street and Multiplex have the capabilities to drive project certainty through their engineering-led approach and collaborative working culture.”
Callum Tuckett, managing director of Multiplex UK, added: “Over the past year, we’ve worked closely with Derwent and the wider project team to develop an approach that will deliver this ambitious scheme to the highest possible standards of quality, sustainability and technical excellence.
“Fifty Baker Street is a significant project for London, bringing together high quality workplaces, homes, retail and community spaces within one of capital’s most established districts. The project also represents a valuable opportunity to advance circular construction in the UK. We look forward to continuing our collaboration with Derwent as we move into this next phase, with preparation to start on site next year.”
