About the space

This grand, circular venue is a masterpiece of Neoclassical architecture, designed in 1939 by acclaimed architect Sir Herbert Baker. Its monumental scale and heritage elegance are crowned by a stunning 30-foot stained-glass dome—an architectural focal point that floods the space with ambient light and timeless character. Ornate English oak panelling wraps the room in warmth, while carefully etched emblems offer a nod to its storied past. The space’s circular structure and elevated gallery seating establish a theatre-like presence, perfect for commanding attention during presentations, panel discussions, and keynote speeches.

With 519 square metres of uninterrupted space, this room accommodates up to 600 people, making it ideal for high-impact conferences, product launches, awards ceremonies, and live-streamed corporate events. Technological capabilities match its historic charm, with live broadcasting, web-streaming, hardwired interconnectivity across rooms, and full air conditioning ensuring modern functionality. Wheelchair access throughout and flexible staging options mean the space is not only visually impressive but also highly inclusive and adaptable.

Make your next event a showstopper—book this one-of-a-kind heritage venue today.
