[4] Initially, 700 harmless chronic female patients lived in single-storey pavilions of wood and corrugated iron radiating from the main corridor.

An isolation hospital was built in the southwest part of the site and an existing farm bordering Horton Lane provided work for the patients and helped the asylum to maintain self-sufficiency.

[3] In 1901 accommodation was added to the site for 100 male patients who were to provide labour for the Horton Estate's Central Pumping and Power Station.

[4] In the 1930s Horton Lodge, a large Georgian era mansion on Christchurch Road, was purchased by the LCC as an annexe for the Manor and West Park Hospitals.

[5] The hospital joined the National Health Service in 1948, and continued to care for moderately mentally handicapped young adults and disturbed adolescents.

[4] Following the introduction of Care in the Community, the hospital was gradually reduced in size as patients were moved into alternative accommodation: by 1990 only 454 beds remained.
