The IHR's first premises were in "temporary" huts on Malet Street, on a site now occupied by Birkbeck College. Despite the supposedly temporary nature of this accommodation, the IHR was not to move until 1947, when it took up residence in the north block of Senate House. The new location was built by architect Charles Holden, along with the rest of the University, at a projected cost of £3,000,000 and duration of 30 years for the whole project. Still occupying this position, many rooms in the IHR overlook the grass lawn in between Senate House and SOAS, which is where Senate House's unbuilt fourth court would have been.
