London's Connaught hotel will next year undergo a multimillion-pound extension and refurbishment.
Thirty-four bedrooms will be added to the iconic hotel in the heart of Mayfair, taking its total to 126.
Existing rooms will be completely refurbished and equipped with state-of-the-art technology while retaining their original features.
The hotel's general manager, Anthony Lee, admitted the project, expected to cost more than £30m, would inevitably mean "a short period of downtime" when the property would be closed.
Lee added: "We want to enhance and preserve the beauty of what we already have but also take the hotel into the 22nd century."
No official date has been set for the work to begin, although it is expected to be in early 2007.
