Located on the ground floor of this spectacular Westminster event venue is the Stephenson room, one of our smaller but really traditional function rooms. This cosy meeting room has high ceilings and large windows allowing in lots of natural daylight. Your delegates will be amazed by the rich, dark oak panelling and the ceilings adorned by beautifully embellished plaster and lit by a large chandelier.
