20 Market Street

20 Market Street is part of a terrace of five tall and narrow three-storey, two-bay houses. The houses feature scribed roughcast fronts, except for No 18, which is pebble-dashed. They have graded slate roofs, although No 22 has had its roof replaced, and each house has a roughcast stack on the right side. The doorways are located on the right side of each house, with blind windows above them. Nos 16 and 20 have retained their panelled doors with three-pane overlights, while No 24 has a fielded-panel door. The other houses have replaced doors and overlights. No 16 still has its original 16-pane hornless sash windows, which are shorter on the upper storey. No 20 features similar horned sashes, and No 24 has 20-pane sashes on the lower two storeys and 16-pane sashes on the upper storey. Nos 18 and 22 have had their windows replaced.

The rear elevation is made of rubble stone, with single-storey projections, except for No 16, which has a two-storey projection. No 24 has a slightly deeper plan, causing it to project in front of the other houses. The original openings have slate lintels, but the windows have been replaced.

This terrace is part of the group of buildings at 16-24 Market Street.
