The works were undertaken in the two-storey Farbey building, workshop and Mews building, which are all within the curtilage of the Grade II* listed Southgate House.  The 3 buildings renovated had a gross internal floor area of 3072 m², the overall site area was 6880 m² which included associated external works, car parking, access roads and landscaping.

The refurbishment and modification provides modern education facilities including a practice flat, vocational facilities for life-skills, creative arts and horticulture, a 6th form common room, therapy rooms and a gym and fitness room.
