About this room

The ground floor of the building is home to the Oak Room, perfect for stylish pre-dinner receptions. The Antique Oak panelling is the predominant feature of the room offering a contrasting reception space for the main event in the Grand Gallery.

The Grand Gallery provides a stunning setting, offering incredible views of Buckingham Palace Gardens and natural light with high-ceilings, chandeliers and elegant tall windows. The room takes a U-shaped form with oak parquet flooring and classical gold cornicing. The Grand Gallery provides the real identity of the building and is equally suitable to host events from product launches to fabulous weddings.
