Wylie Hill's, 20 Buchanan Street, Glasgow

Wylie Hill's is a large department store located at 20 Buchanan Street in Glasgow, designed by John Hutchison with details by Andrew Black and assistance from Charles Rennie Mackintosh. The building was rebuilt in 1889 for Robert Wylie Hill after a fire in 1888 and suffered further fire damage in November 1903, leading to reconstruction the following year, during which an additional storey was added.

This six-storey commercial building, styled in the Italian Renaissance, features an attic and three tripartite bays. It is constructed from orange-red Corsehill sandstone and has large windows with the glazing set directly into the masonry. The ground floor has a modernised shopfront. The first, second, and third floor bays are separated by pilasters of varying sizes, either rusticated or banded, with central lights in each bay supported by elaborately designed Ionic columns. The second floor's central light is pedimented, and there are panelled pilaster strips on the fourth and fifth floors. A modillion cornice runs along the top, and the attic features a central square-domed pavilion with intricate pilastered and colonnaded details, along with pedimented dormers on either side. The south side windows have plate-glass casement and top hopper windows with small-pane glazing.

Photographic evidence from 2012 shows that unique Ionic capitals, likely from 1889, are present on the ground and first floors of the interior. Sales particulars from 2024 indicate that these capitals also remain on the fourth and fifth floors.
