Queen's Gate House, still commonly known by its previous name of Baden-Powell House, is a conference centre in South Kensington, London. It was built as a tribute to Lord Baden-Powell, the founder of Scouting, and has served as the headquarters for The Scout Association, as a hostel providing modern and affordable lodging for Scouts, Guides, their families and the general public staying in London and as a conference and event venue.

South Kensington is a district just west of Central London in the Royal Borough of Kensington and Chelsea. Historically it settled on part of the scattered Middlesex village of Brompton. Its name was supplanted with the advent of the railways in the late 19th century and the opening and naming of local tube stations. The area has many museums and cultural landmarks with a high number of visitors, such as the Natural History Museum, the Science Museum and the Victoria and Albert Museum. Adjacent affluent centres such as Knightsbridge, Chelsea and Kensington, have been considered as some of the most exclusive real estate in the world.
