Treatment spaces include a variety of room types ranging from specific treatment for individuals, to group rooms and multi-bed wards (some facilities will have individual bedrooms which are covered separately in this guide). Rooms need to be secure and safe, whilst potentially including a toilet, a waiting area, office/bedroom with en-suite. Therapy rooms can be for relaxation, music, drama or similar so consultation with staff is key to achieving the correct design.
