The Regent Theatre was built in 1927 as the largest and most ornate theatre in Brisbane. The magnificent decorative plasterwork within the theatre building has been admired by visitors of all ages for many decades.

In 2014 and 2015, McMillan Heritage Plastering carried out traditional plaster conservation works to the original fibrous plaster ceilings and decorative balconies in the Grand Foyer room. Cornice and pier capital restoration works were also completed in the Grand Entrance, along with decorative wall panel repairs in the adjoining Aromas coffee shop.
