Description
The Great Western Hotel is a Gothic-style hotel building located on a rounded corner site, constructed in the 19th century. It stands three storeys tall and is faced in random stone, primarily Radyr stone, with bathstone dressings and slate roofs. The windows feature plate tracery, and there are corbelled turrets, although the pinnacles have been lost.
The entrance block includes a tower topped with a steep pyramidal roof that has two levels of louvres. The top floor features paired 2-light windows, while the first floor has a 2-light Gothic window and a Gothic doorway with a modern canopy. On either side of the tower, there are narrow bays with gabled dormers that enclose Gothic windows. Below these, there are round windows and 2-light square-headed windows. The ground floor has a blocked doorway with a cinquefoil in a Gothic head.
To the right of the entrance block, there are four gabled bays, each with a 3-light Gothic window on the top floor, a 2-light Gothic window on the first floor with panelled aprons, and a 2-light Gothic window under a straight hood on the ground floor. To the left of the entrance block, there are seven bays that mirror the design of the right side, with doors under modern canopies for two of the bays. Beyond a buttress, there is a broader bay featuring a stone balcony on the first floor and a 3-light window on the ground floor. A similar bay is located at the splayed corner, where the upper window is recessed and there is a camber-headed doorway. The west side of the building has a two-window elevation.
