One Birdcage Walk

Venetian palazzo marble over a chequerboard floor, with fireplaces along both walls, brass chandeliers and a stone staircase at the far end. The adjoining Gallery is a lighter, timber-floored room with changeable coloured lighting, used together with the hall for receptions and exhibitions or on its own for catering and registration. Both spaces carry a wall-mounted sound system, and a cloakroom is built in.

Two storeys of oak shelving under a gilded ceiling, with a wrought iron balcony running round the upper level, original fireplaces and windows over St James's Park. It takes long tables or rounds for dinner and works as one room for a standing reception.

Edwardian oak panelling, gilt chandeliers, an ornate ceiling and two fireplaces, on the second floor with a kitchen next door. It rearranges easily between a long table, rounds and a standing reception, and has its own registration table and coat rail outside.

A first-floor room with restored gilt ceiling detail and a reinstated fireplace, looking over St James's Park. Changeable coloured lighting and a catering space inside the room make it the easier of the two large panelled rooms for a drinks reception.

A first-floor room with tall windows, heraldic shields on the wall and pieces from the Institution's Whittle holdings. Often taken as the catering or breakout room for an event in the Manufacturing Room next door.

On the ground-floor Presidential corridor, holding the desk that belonged to George Stephenson, the Institution's founder. Its position beside the Lecture Theatre makes it the natural green room for speakers at a larger event.

Part of the Presidential Suite: an oak-panelled room with a marble fireplace, its own reception area and a private cloakroom outside. Hired alone for an intimate dinner or with the suite.

A dual-aspect first-floor room with a portrait over the fireplace, a screen and conferencing camera built in, and space for catering inside the room.

A bright first-floor room named for the automotive and aerodynamics engineer, with a round table, a wall-mounted screen and a conferencing camera for hybrid work.

A small ground-floor room with arched windows, a screen and catering space inside. Close enough to the Lecture Theatre to serve as a private meeting room or green room during a larger event.
