1,3 and 4, Unity Street

Nos. 1, 3, and 4 Unity Street is a terrace of three houses, now used as offices, built around 1742, possibly by James Paty the Elder. The buildings are constructed of limestone ashlar with brick party wall stacks and feature a pantile hipped roof. They have a double-depth plan and are designed in a Palladian, mid-Georgian style.

The terrace is symmetrically arranged, each house having three storeys, an attic, and a basement. The middle house has a five-window middle range and three-window outer ranges. It features rusticated pilaster strips on the party walls, a cornice and parapet, and a rusticated ground floor with a plat band. The middle house has a distinctive 1:3:1 arrangement, with rusticated quoins framing a pedimented centre that is slightly advanced. The central doorway is adorned with blocked Ionic pilasters, a pulvinated frieze, a pediment, a rectangular overlight, and an eight-panel door. The outer houses have semicircular-arched doorways on the left, with similar decorative surrounds to the centre, fanlights, and six-panel doors.

The buildings have 20th-century plate-glass shop fronts, with architraves and sill blocks on Nos. 2 and 3, while No. 1 has plain, segmental-arched heads. The windows include 6/6-pane sashes and 3/6-pane sashes on the second floor, along with two hipped dormers. The rear elevation of No. 4 features an early 19th-century addition with six Doric columns supporting an entablature with metopes.

Inside No. 1, there is an entrance hall with a panelled division from the front room, a semicircular arch with panelled reveals leading to a side dogleg stair with column-on-vase balusters, a moulded ramped rail, and panelled wainscot. The interior also includes six-panel doors, panelled shutters, and fireplaces.

Historically, the terrace is named after the reconciliation between George II and Frederick, Prince of Wales. It is likely the earliest of a group that includes Nos. 5-9, with its early Palladian facades setting a trend that influenced architecture into the 19th century.
