Looking east from the Hospital Ward toward the back of the Main Building.

Because of overcrowding many additions and outbuildings were added over the years. By the end of the Second World War, the patient population had soared to over 1600 with no end in sight. as WWII mental cases started arriving. To answer this need. a rehabilitation facility was built in 1948, a forensics department later that year. Then a new wing holding Arts and Crafts was added, extending behind and perpendicular to the Second wing, north of the main structure. As a result, the north and south ends were no longer identical, a departure from symmetry that would surly have offended architect Richard Snowden.

In 1953 another building was added exclusively for geriatrics and the former laundry/segregated ward/orphanage building was torn down and replaced by a maintenance facility. Despite these improvements conditions at the asylum remained grim.
