The Langham London is to invest a further £7.5m in the refurbishment of its luxury hotel over the next year.
Three new areas are due to launch as part of the upgrade to the hotel, which is its most extensive since 2009 when it was reopened after a £80m refurbishment.
When completed the hotel will feature the new Regent Wing, which will see the Club wing reworked to have 46 rooms and suites all decorated in the Regency period style.
The new Sterling Suite will also open in April 2015 with up to six bedrooms and other rooms covering 450 sq m. The suite will have a personal butler service; private media lounge and special security features.
Work has also commenced on the new Langham Club Lounge that will feature private check-in/check-out; an adult-only Drawing Room and library.
