10-20, Sun Street

Nos. 10-20 on Sun Street in Lancaster is a terrace of six houses, one of which is now a shop. These houses were built in the late 18th century and have been altered in the mid-19th and 20th centuries. They are constructed from sandstone ashlar in narrow courses and feature a slate roof. The buildings have a double-depth plan and are designed as three pairs, each with linked doorways in the center, side rear extensions, and gable chimney stacks. However, No. 10 has a deeper plan and a staircase located in the rear extension to the right.

The terrace consists of three storeys above cellars, with one bay per house. The doorways have plain surrounds and six-panel doors, while the windows have plain reveals. No. 10 has had alterations to its first-floor windows, which now feature a pair of glazing bar sash windows. On the ground floor, there is a wide opening with chamfered reveals that has been filled by a shop front with canted sides and a full-width timber fascia topped with a segmental pediment in the center.

Nos. 18 and 20, located on the left, have late 20th-century bow windows on the ground floor, with the right-hand one set under a concrete lintel, and steel balconies on the first floor. Their first- and second-floor windows are glazing bar sashes. No. 16 has a glazing bar sash on the first floor, while No. 14 features similar windows on both the ground and first floors. The remaining windows in the terrace are either four-pane sashes or 20th-century casements. The rear elevation includes full-height stair windows at the center of each pair, except for No. 10.

Historically, this terrace was likely built shortly after the creation of Sun Street, which was laid out in 1791 on the garden of the Sun Inn on Church Street.
