30, Blackett Street

No. 30 Blackett Street is a shop and offices built in 1902 by Marshall and Tweedy for W. Glendinning. The building is constructed of sandstone ashlar and features a dark slate roof. It stands five storeys tall with an attic and has two bays. The ground floor shop was altered around 1980. The building has stone mullioned and transomed windows, with the left window being narrower, all set in lugged and aproned architraves with cornices. There is an Ionic window case above with a swagged frieze and an open and broken pediment.

To the right, a four-storey canted bay features a broken first-floor pediment with a coat of arms, swags between the second and third floors, and a balustraded balcony on the fourth floor. The top of this bay has a lunette flanked by squat Ionic pilasters that support a deep, keyed hood. The left bay includes an attic sash window in a square turret, which has diagonal pilasters and a coped, shaped parapet. The mansard roof is topped with a tall chimney that has a string course and cornice.
