The Four Seasons Hotel in Park Lane, London, has closed for a major refurbishment.

ReardonSmith is leading the design team responsible for the revamp, which will see a two-storey extension of the north west elevation in order to provide a new executive suite. On the ground floor, a new porte cochere will also built and a new staircase introduced.

The building’s double height atrium will be restored and include a Tea Lounge area with gallery space.

There will also be a rooftop extension to make for a new spa and fitness suite. The spa will be designed by Eric Parry Associates.

The interior design is being carried out by Pierre-Yves Rochon, which will see all eight floors of guestrooms redecorated.

The hotel will reopen next year.
