The Wikipedia entry on Weedon has this to say:
There was also a barracks in the village, holding a standing battalion, plus a troop of cavalry and a troop of horse artillery. The barracks were demolished in the 1950s. Three large pavilions were built between the depot and barracks to house the senior civilian officers of the depot. These were demolished in the 1960s. Next door to the barracks was the Army School of Equitation, also demolished in the 1960s. The depot became redundant in 1965 and was sold by the Ministry of Defence in 1984. It is now used for storage and light industry.
