About this room

The Marks Room is our smallest space, so it is ideal for intimate meetings and presentations. It is appointed as a formal meeting room with a boardroom table and chairs, accessible directly from the impressive reception hall of Number 10. It is a bright, practical room with a large window overlooking the Duke of York’s Column and Steps.

Rules of the space

Most events are absolutely fine just bearing in mind that we are Grade 1 heritage listed building.

Whether you are looking for a boardroom for a discreet meeting or a selection of distinct suites for a major conference, reception or fine dining occasion, {10-11} Carlton House Terrace provides versatile spaces and unrivalled standards of service. Twelve different rooms are available to hire, from 2 – 200 people, each offering their own unique style. Many of our rooms feature floor to ceiling windows, creating light and relaxed environments.

{10-11} Carlton House Terrace was built during the late 1820s and early 1830s on land previously occupied by Carlton House, the residence of the Prince Regent, who became George IV.
