London Marriott Hotel Park Lane is scheduled to finish an extensive refurbishment in June.
All of the property's 152 rooms are undergoing renovation that includes entrance lobbies, five new suites are being introduced, while the lobby, executive lounge and meeting rooms have all been redesigned.
The hotel is also installing technology including Apple products, bluetooth LCD screen televisions and mobile check-in.
The works are being overseen by RPW Design.
Jan Wilson, the firm's managing director, said: "Our designs aim to bring out the English Heritage of the Francis Verity designed historic building extending its intimate feel and residential character into the hotel’s interior.
"Elegantly designed rooms and public spaces will have all the facilities expected in a leading luxury hotel."
Nicolas Kipper, the hotel's new general manager, added: "The new design, an increased suite count, an elevated service and an enhanced in-room offering, will make us even more appealing to the luxury market."
London Marriott Hotel Park Lane will announce renovation plans for The Club, which contains a steam room, gym and swimming pool, in due course.
It was recently announced that Marriott International will next year provide free wifi to all 47 million of its loyalty programme members (see news, October 31).
