The site is of irregular shape and relatively flat. It is bound to the perimeter by fencing and vegetation.

Historically, The Hollies was occupied as an outpatient facility by the Southern Health NHS Foundation Trust as a part of the adjacent Parklands Hospital. It was acquired by Homes England in 2018 which has subsequently demolished buildings and associated foundations to a depth of 3m with excavations backfilled and a small area of hard standing also remaining. Services are understood to have been isolated to the boundary of the site.

Currently access to the site is from Aldermaston Road to the east.
