Description

Numbers 10 and 11 Lemon Street, also known as No. 1 Back Quay, is an early 19th-century town house that has been converted into a shop with accommodation above. The building features a stucco exterior on studwork and has a hipped asbestos slate roof with brick end stacks. It has a three-room-deep plan and stands three storeys tall.

The front facing Lemon Street has a two-window range, with flat stucco surrounds and moulded hoods above late 19th-century horned four-pane sash windows. The left side of the first floor has an additional window. The ground floor includes five segmentally-headed openings, with a doorway on the left, which features a three-light shop front with its doorway towards the right. This area has moulded architraves and a moulded cornice supported by consoles.

On the Back Quay side, there is a three-window range. The left-hand bay is similar to the Lemon Street façade, while the second bay is similar but lacks a cornice. The right-hand bay has openings that are set lower and features a circa early 20th-century double shop front with a sloping fascia and terminal consoles. The interior of the shops has been modernised and was not inspected further.
