In 1860, Douglas had heard about the government's plans to build a water reservoir and park on the island's south-western part at the valley around Pok Fu Lam.

Pok Fu Lam Road soon developed as the connection of the Western district to the smaller harbor of Hong Kong in Aberdeen, where Douglas planned to set up his docks.

In 1861, he bought the 900 square meter hill, which includes the location of today's University Hall, the High West and tennis courts.

The gross building area of the castle was around 2000 square feet, which was a two-story structure, located at today's Warden Flat.

The government, which considered the castle for numerous purposes, finally decided to grant the building to the University of Hong Kong.

When completed around 1867, the single-storey compound provided an octagonal penthouse bedroom that faced directly the sea and being surrounded by hill and the nearby water reservoir, the villa also included a side house and a rectangular outhouse.

With the change in ownership to the French Missionaries in 1894, a new wing, a chapel and printing house on the north-eastern was erected in accordance with the existing style under the architects Danby, Leigh, and Orange to meet the development of the commission.

Apart from participating in interhall competitions, it also actively organizes and joins different activities, including a yearly Halloween ball in which the castle turns into a haunted house, Current Affairs Forum, Round Island Bike Trip, Drama Public Show and Fire Dragon crafting.

University Hall offers a number of sports, such as lacrosse, softball, hockey, dragon boat, table tennis, badminton, soccer, athletics, and snooker.
