The oldest building on the site, currently known as The Croft, was used in part for accommodation and as a training centre from early on in the centre's use but took time to renovate due to the poor condition of parts of the building and to convert the various buildings from their farm uses. It was extended in 1991 and 2008, which is today occupied by reception and the Ferny Crofts offices, and again from 2007 to form a conservatory at the rear, to be named the Sky High Conservatory in recognition of the Hampshire Scouts who reached the summit of Mount Everest in 2007. A self contained accommodation unit, the Inca Suit, was constructed in 2009 as part of the complex.
