Come and explore Dartmouth House on Sunday 22 September

Open House London

An architectural gem

Dartmouth House is an opulent Grade II*-listed townhouse boasting a marble courtyard, French panelling and a Robert Adam fireplace. It is home to the English-Speaking Union, an educational charity equipping young people with the speaking and listening skills and cross-cultural understanding they need to thrive. The house you see today is actually two houses, nos. 37 & 38 Charles Street, combined between 1890 and 1891 by banker Edward Baring, one of the most conspicuous consumers of the decade, who had been raised to the peerage as Baron Revelstoke in 1885.


We will be holding seven guided tours throughout the day (approx. 40mins long). These will run on the hour from 10am until 4pm. Booking is essential and will open on this website on 20 August.

Dartmouth House information booklets are also available, free of charge, at reception for self-guided tours throughout the day, or can be downloaded here. Activity sheets for children will also be provided.

Book your next event at the house

Dartmouth House is available for hire for weddings, private dining functions and events including conferences, product launches and lectures. Meeting rooms are also available. Over thirty percent of all proceeds from Dartmouth House events go towards supporting the English-Speaking Union in its charitable work, equipping young people with the speaking and listening skills and cross-cultural understanding they need to thrive.

About the English-Speaking Union

The English-Speaking Union believes every child should be able to make their voice heard. We believe that the ability to progress and thrive in life relies on oracy – speaking and listening – skills, skills which are not currently a prominent part of the state school curriculum. Our debate and public speaking programmes help young people to engage with complex ideas more effectively and, just as importantly, to listen. These skills improve young people’s attainment, self-esteem and social skills, helping them to achieve their goals and to change their lives and communities for the better.
