Bush House is a Grade II listed building at the southern end of Kingsway between Aldwych and the Strand in London, England.

It was conceived as a major new trade centre by American industrialist Irving T. Bush, and commissioned, designed, funded, and constructed under his direction.

[2] Now part of the Strand Campus of King's College London, Bush House previously served as the headquarters of the BBC World Service.

The final BBC broadcast from Bush House was the 12 noon BST news bulletin on 12 July 2012.

Irving T. Bush gained approval for his plans for the building in 1919, which was conceived as a major new trade centre and designed by American architect Harvey Wiley Corbett.

Built from Portland stone, Bush House was in 1929 declared the "most expensive building in the world".

[13] A full refurbishment of Bush House and its adjoining wings was undertaken by John Robertson Architects following the BBC's vacation.

[16] as a substantial part of its expansion of its Strand Campus[17][18][19] John Robertson Architects undertook the interior fit-out to convert Aldwych Quarter into a fully operational, modern university campus, including installation of a 400 seat auditorium, lecture theatres, seminar rooms, academic offices and a health centre.

The courtyard has been converted from car parking to semi-public realm and features a new glass pavilion offering access to the Students' Union and undercroft joining the building's wings together.

[22] King's College London Students' Union (KCLSU) also occupies Bush House.
