Brent Mathews, Property Director, BT Group said: “The BT Tower sits at the heart of London and we’ve been immensely proud to be the owners of this important landmark since 1984. It’s played a vital role in carrying the nation’s calls, messages and TV signals, but increasingly we’re delivering content and communication via other means.

“This deal with MCR will enable BT Tower to take on a new purpose, preserving this iconic building for decades to come.”

Tyler Morse, CEO and owner of MCR Hotels, said: “We are proud to preserve this beloved building and will work to develop proposals to tell its story as an iconic hotel, opening its doors for generations to enjoy.”

MCR Hotels own around 150 hotels, including the historic landmark Eero Saarinen-designed TWA Hotel in New York City.

Payment for the sale will be made over multiple years, as BT Group equipment is progressively removed from the building, with final payment on completion of the purchase.
