10-15 Princes Street, Edinburgh

10-15 Princes Street in Edinburgh is a former Woolworths building, likely designed by W Priddle in 1925, with a western portion added in 1956 and an early 19th-century block at the rear. This three-storey and attic structure is situated on a prominent corner site and features a canted corner with an ogee-roofed octagonal tower. The exterior is made of polished cream sandstone ashlar, and the ground floor has modern shops beneath the original cornice. The first and second floors are adorned with a giant Roman Doric order, complete with an entablature and a mutuled cornice, and the first floor has balconies between pilasters. The building has a mansard roof with rectangular attic windows and an ashlar tower at the corner with segmental open pediments on the south and east faces, which contain keystoned oculi.

On the Princes Street elevation, there are 13 bays with a modern canopy for the shops and five dormers. The east elevation consists of five bays, with the three right bays being broader and divided by paired pilasters, featuring tripartite windows. The principal corner design is similar to that of the Princes Street elevation, with the north bay showcasing an ashlar attic storey and an earlier curved corner on the rear elevation. This elevation also has two dormers.

The rear elevation features an early 19th-century scabbled ashlar quadrant corner with three adjoining rear bays, including pilasters at the ground level, architraved corniced windows on the first floor, a cill course on the second, and a cornice with a 20th-century attic. A large tripartite window has been inserted above the loading bay to the right. To the west, there is a mid-19th-century four-storey, seven-bay block with lugged architraved windows, which has been much altered, along with a modern block beyond.

The building has mullioned and transomed metal windows, with an internal arch at the first floor. The mansard roof is covered with grey-green slates, and the dome is lead-covered. The interior has been converted into modern retail units.
