The company, owner of Soho Coffee Company, Apostrophe cafés and Euphorium Bakery, will invest £125m in the acquisition and building work to turn the historical property, once the home of the Bow Street Runners, into a luxury hotel.
Earlier this year former owners - Austrian hoteliers Rudolf and Christian Ploberger - secured planning permission to turn the 90,000 sq ft former court house, which hosted the trials of Oscar Wilde and the Kray twins, into a hotel with plans to open in two years' time.
Mehdi Ghalaie, managing director at BTC UK, said: “Bow Street Magistrates' Court is an iconic part of London’s heritage and we are delighted to be bringing it back into public use. After many years under different owners, our focus is now on delivering a world class boutique hotel that befits the history of this landmark building.
“We will be engaging with English Heritage, Westminster City Council and the Metropolitan Police in our planning process to maintain the building's illustrious legal heritage and history and to ensure that the traditions and spirit of Bow Street are preserved.
“This acquisition further enhances our expanding hospitality credentials in the UK and reflects our desire to develop businesses that provide unparalleled customer experience.”
BTC UK - the UK arm of BTC in Doha, was founded in 2015 when it bought Soho Coffee Company.
Michael Elliott acted for BTC UK and Gerard Nolan & Partners co-invested and acted for the Plobergers.
