Description

Nos 19 and 20 Bolton Street are a pair of terrace houses built in the early to mid 18th century, with some alterations from the early 19th century. They are constructed of darkened brick with rusticated stucco on the ground floors and feature slate roofs. The buildings rise to four storeys, with basements and dormered mansards. Each house has three windows across the front. The doorways are semicircular arched and recessed, located to the left and off centre to the right, with altered doors and plain fanlights. The upper floors have recessed sash windows without glazing bars, set under flat gauged brick arches. A main stone entablature runs across the fronts above the second floor. No 20 has a string course at the first floor and a stone cornice below the parapet, while No 19 features a patterned cast iron balcony from around 1800 across the first floor. The area railings are made of cast iron, with No 19 displaying foliated spearhead finials and No 20 featuring flambé torch finials.
