About this room

On the ground floor to the rear of the main foyer in this spectacular Westminster event venue is the Stephenson room – one of our smaller yet traditional-style function rooms.

The event space, although slightly smaller than some, has high ceilings and large windows along the west wall allowing in lots of natural daylight. The walls are partially covered with rich, dark-oak paneling and the ceilings are adorned with beautifully-embellished plaster and lit by a large chandelier. There is a grand fireplace on the South wall framed by a splendid dark wood mantelpiece, above which hangs the portrait of Isambard Kingdom Brunel one of the Institution’s most noted past presidents.
