11 Penlan House

11 Penlan House is a two-storey building featuring scribed rendered fronts. It has two windows for No 11, one window for No 13, and three windows for No 15. The roofs are covered with slate, which has been renewed for No 15. There are very tall stone chimney stacks for Nos 11 and 13, with one stack having a stock brick flue, while No 15 has a low pebbledashed stack. The eaves are boarded. The first floor has sash windows, with 4-pane windows for Nos 11 and 13. The ground floor has modern shop fronts, and No 11 features a six-panel door with a splayed entrance. No 15 has a modern glazed door at the extreme right end and a splayed corner entrance supported by two cast iron pillars, with the shop front overlapping the corner.

The left end of the building is pebbledashed and includes a modern window and a chimney stack at the rear. At the back, there is a two-storey and attic cross range with a slate roof, facing Market Square, which has a gable at the rear of No 15 that features a 4-pane attic window, although the rest has been modernised.

The interior has been largely modernised but retains the original roof structure with chamfered purlins. There is a dog-leg staircase, with the lower part boarded in and turned balusters further up. Some panelled doors remain.
