30, Grainger Street

No. 30 Grainger Street is a commercial building constructed between 1884 and 1886 by John Johnstone for the Newcastle and Gateshead Gas Company. It is designed in the French Renaissance style and built from sandstone ashlar with slate roofs. The building stands three storeys high with attics and has a basement on the south front facing St. John Street. It features three wide bays on each side, plus an angled corner bay.

The ground floor has been altered on the west front to accommodate shop windows, and the central bay on both fronts projects forward with a two-storey rounded oriel topped by a balustraded parapet. This is supported by an elaborate three-stage pilastered gable that leads to a pavilion roof. The side bays have shallower square pilastered projections and smaller pedimented two-stage attic gables. The corner bay features an oriel supported by a heavy rounded and moulded corbel, rising to a dome with a smaller drum, dome, and finial above.

The building's horizontal stability is enhanced by banded rustication on the narrow wall spaces and by entablatures with panelled blocking courses at the floor levels. Each bay contains three or four plain windows.
