33 College Street

33 College Street is a two-storey building with an attic, constructed from red and yellow brick with red and yellow terracotta dressings, topped with slate roofs and red tile crestings. It features two facades, including a canted corner entry. The facade facing College Street has a two-window range, while the side on Margaret Street has a five-window range arranged in a 1-3-1 pattern.

The ground floor is distinguished by large plate-glass windows from the 20th century, which are divided by striped brick piers and topped with broad yellow terracotta heads. These heads are nearly flat with rounded angles, composed of yellow voussoirs with moulded red center keystones and red roundels on the angle spandrel pieces. The piers and windows are narrower for the three central openings on Margaret Street, and the corner entry features recessed modern aluminium and plate-glass doors. Above the ground floor, two moulded strips create a sill-band framing a red brick band adorned with yellow terracotta decoration. This decoration includes the words 'Co-operative Society Limited' on both sides and 'Ammanford' above the entry. The longer side on Margaret Street has additional runs of pressed square tiles.

On the first floor, the windows are framed by yellow brick rusticated jambs, with a yellow brick band at one-third height, a moulded yellow terracotta impost band, and flat heads with rounded angles. These heads feature red terracotta keystones and spandrel roundels. A red moulded stringcourse runs beneath a white-painted eaves band, which is broken forward over the keystones. The moulded stringcourse steps over the window in the entry bay, and there is chequered brickwork above, leading to white stucco with an attic window, all beneath a steep bargeboarded gable. The windows on the first floor and attic have six panes in the top sash and two in the lower sash. A small sash window is located in a stucco gabled dormer at the center of the Margaret Street front.

On the first floor, within the yellow brick band, there are inset blue brick lozenges featuring moulded red terracotta plaques that date the building to 1906, with two plaques on Margaret Street and one on College Street. The interior has been altered.
