The Emlyn Arms Hotel, including attached ranges each side of rear outbuildings

The Emlyn Arms Hotel is a large inn from the mid-19th century, accompanied by extensive outbuildings. The main hotel building is three stories tall with three windows, facing a slate-paved terrace. On either side, there are low two-story ranges; the left side features an archway leading to the rear courtyard, while the right side has a plain four-window range that also faces a terrace. The rear courtyard contains an L-plan range of outbuildings on the south and west sides.

The main building has a whitened roughcast front with some raised painted stucco dressings added in the late 19th century. It has a half-hipped roof and yellow brick end stacks. The upper floors feature late 19th-century four-pane sash windows with stucco hoodmoulds above the square second-floor windows, and stucco labels above the large first-floor windows, all with slate sills. The ground floor includes late 19th-century canted bay windows with 2-4-2-pane sashes and a central six-panel door with a margin-glazed overlight. A large late 19th-century timber open porch, similar to that of the Plough Hotel in Emlyn Square, has chamfered piers, a nogged cornice, and stained glass top-lights.

The right range is lower and roughcast, with a slate roof and two brick stacks. It has four sash windows on the upper floors with late 19th-century raised labels. The ground floor has been mostly altered, featuring a window to the left and three to the right, with the center one previously a door and the end one wider than the others, all with matching stucco labels.

The left range is smaller, with two four-pane sashes above a carriage entry and a small shopfront. The shopfront on the left has a simple later 19th-century timber pilaster and fascia framing, with a two-pane window and door. Behind this, there is a whitewashed L-plan service range with slate roofs; it is single-story adjoining the entrance arch and rises to two stories on the south side, featuring a corner hipped-roofed range and a louvred lantern. A two-story range returns to the north.
