83, Harmire Road

No. 83 Harmire Road is a former railway junction keeper's house, now used as an office, built around 1856 for the Stockton and Darlington Railway Company. The building is constructed from snecked stone with ashlar quoins and dressings, topped with a Welsh slate roof and a stone chimney. It has a low, one-storey structure with an L-plan layout and a two-window range.

The central entrance features a renewed six-panel door with a small overlight, set in alternate block jambs beneath a flat stone lintel and a wooden-bracketed sloping stone hood. On either side of the door are paired renewed four-pane sash windows, which also have similar jambs and lintels, along with projecting stone sills. The low-pitched roof has gable coping at the right end, with block kneelers, and a small square chimney on the right end with a top band.

The left gable is built over by an adjacent house. A square plaque from the railway company is located on the right, displaying a painted low relief shield with the letters 'F 10' and 'S & DRC' at the base of the shield. The right return of the building has a blocked door, and there is a gabled rear wing with a chimney, along with a 20th-century flat-roofed rear extension.

The interior has not been inspected.
