[1] After the war, in 1922, the Royal Army Service Corps (RASC) took over the site and buildings to serve as its Mechanical Transport Depot.

(Believed to have been built in the 1770s for the Villebois family, the house (then known as Feltham Place) passed through several owners, serving for a time as a boys' school before being bought by 'Cabbage King' Alfred Smith in 1897.

It continued in use as an officers' mess through the 20th century (and was extended in the 1960s); however, as of 2018, it is unoccupied and has been placed on the Heritage at Risk Register.

[6] In the 21st century the site remained in use as the Defence Geographic Centre (DGC) 'its primary role [being] to provide land maps, aeronautical charts, positional information, geo-referenced imagery and digital data in [various] formats for UK defence planning, operations and training'.

In 2012 DGC had a (largely civilian) staff of 400; its library included a global collection of over 700,000 maps, charts and atlases.
