Castle Chambers, 59-69 Renfield Street, Glasgow

Castle Chambers, located at 59-69 Renfield Street in Glasgow, is a commercial building designed by Frank Burnet and Boston between 1898 and 1902, featuring sculpture by Ernest Gillick. This five-storey structure, with a double attic and basement, has a polished red ashlar facade and is organized into ten by six bays. The ground floor, which rises to the full height of the street, has channelled strips and a plinth that forms a cill band. The windows are sash and case, with plate glass, and there are blocks around the windows on the first and fourth floors. The ground floor has been partly altered, particularly along Renfield Street.

The entrance at No. 69 Renfield Street features a segmentally scrolled pediment with a sculpted tympanum. At 57 West Regent Street, there is a columned doorpiece with a segmental pediment.

The corner bay is a full-height canted bay that is corbelled out on sculpted brackets, supported by columns with figure sculptures in the outer bays. A sculpted frieze adorns the first floor, with simple pilastered mullions on the second and fourth floors. The tower breaks through the roofline, featuring a cornice supported on columns and a blocked oval oculus in each bay, topped with a polygonal bell-cast roof and a colonnaded lantern.

On the elevation facing West Regent Street, there is a full-height canted bay in the fifth bay from the east, with another canted bay above the first floor in the third bay, and over a six-light ground floor window. A balcony is present at the first floor above the entrance, with aedicule windows at the second floor above and in the west bay. The third and fifth bays on the third floor have segmentally pedimented windows, and there is a modillion cornice. Aedicules serve as dormers set in gables, featuring two and three-light pedimented windows, along with elaborate relief sculptures, finials, and balustrades. Axial stacks are also present.

The elevation to Renfield Street continues the detailing from the West Regent Street elevation, with canted bays corbelled out and featuring balustraded balconies in the first, second, and sixth bays from the south. The south corner turret is corbelled out with sculpted stops at the fourth floor, and there is a balustraded parapet with a single gable that has a segmental aediculed window and a sculpted finial. The detailing on West Regent Lane is simplified.
