6-8 Castle Street, Edinburgh

6-8 Castle Street in Edinburgh is a three-storey and attic office building designed by Thomas Leadbetter in 1889, with some later alterations. The building features a symmetrical, four-bay French Renaissance style that projects slightly from the street line. It has moulded architraves and a modern shop at the ground level, along with an entrance to the offices above.

On the first floor, there is a plinth with Doric pilasters situated between the windows. The outer windows next to the central ones are wider and adorned with elaborate carved crests, topped by a cornice. The second floor showcases individual pedestals with fluted Ionic pilasters paired with broader piers and shouldered architraves. The eaves cornice is complemented by a balustraded parapet, and there is a broad slate-hung box dormer over the three right bays.

The building has multi-pane timber windows, with casements on the first floor and 20-pane windows on the second floor. There is a rendered stack on the inner left and a stone mutual stack on the right, all covered with grey slates.

Inside, the first-floor front room features timber panelling, a chimneypiece framed by paired fluted Ionic pilasters, and an enriched panelled ceiling. The rear rooms are separated by a massive archway, which is also repeated on the second floor.
