Number 55 (Darlington House) and Numbers 57 and 59 and Garden Wall in Front of Nos 55, 57 and 59

Number 55, known as Darlington House, along with Numbers 57 and 59, features a garden wall in front of all three properties. This terrace, originally called Gloucester Place, was built in 1817 and is constructed of stucco. It has a parapet and a slate mansard roof with half-hipped ends. The buildings rise four storeys, including an attic and basement.

Each house has an arched porch with open pediments supported by Tuscan columns, a traceried fanlight, and panelled doors. They also feature sash windows with glazing bars and segmental bowed bay windows made of sashes with glazing bars on each floor. Number 55 has a three-storeyed canted bay window with sashes that do not have glazing bars, replacing the original bowed window. The properties include square-roofed dormers with sash windows that have glazing bars.

There is a flight of steps leading to each doorway, accompanied by iron railings with turned newels. The terrace is elevated above the road, with gardens set on a red brick terrace wall topped with iron railings featuring arrow-head shafts.
