Bbc, 30 Queen Margaret Drive, Glasgow

The building comprises two distinct sections, a Renaissance villa constructed between 1869 and 1871 by J T Rochead, later adapted for educational purposes, and an Art Nouveau extension designed in 1895 by John Keppie in collaboration with Charles Rennie Mackintosh. A further addition by James Miller was made in 1936, alongside subsequent alterations. Originally a medical building for Queen Margaret College, the southwest part is two storeys and five bays wide, built in polished ashlar with rusticated angles and decorative entrance strips. It features sash and case windows with four panes to each window. The main entrance is distinguished by a central Doric portico with coupled columns, a panelled frieze incorporating triglyphs, a mutule cornice, and a balustrade above. Ground floor windows are recessed, with mask keyblocking, arched surrounds with moulded archivolts, and panelled aprons. A dentil band runs along the ground floor, leading to a cornice. The first floor has blind balconies and a tripartite central window supported by scrolled elements. A deep, bracketted modillion cornice incorporates a dentil band, surmounted by corniced parapet walls with a ground floor balustrade. The south return echoes the main elevation detailing, with single-light windows on the first floor. A 1936 extension to the south return comprises seven main bays, with a lower east bay, featuring channelled ashlar at ground level and two aediculed windows on the first floor, each topped with consoled segmental pediments. A dentil band and cornice cap the elevation. The interior of the southwest section includes a double-height entrance hall with coupled Doric columns and an arcaded gallery. It showcases elaborate plasterwork, top lighting via oculi, compartmentation, cornicing, and a barrel-vaulted ceiling. The northeast section, a two-storey, L-shaped extension, incorporates a facetted stair tower. Constructed with snecked rubble, it has a projecting entrance bay attached to the tower, above which sits a sculpted panel bearing the date. A stylised balustraded balcony is positioned above the entrance. Three simple, narrow single-light windows are located to the right of the entrance. A swept parapet and an elliptically arched opening define the eaves. To the left are two sash and case windows with eight panes per window, accompanied by keyblocked, shaped lintels. The stair tower features narrow stair lights, an open-arched belfry with an impost band, a corniced top, and a bell-cast roof. A rubble and ashlar boundary wall encloses the site, along with cast iron railings and an entrance gate to the west, supported by channelled, corniced piers with sculpted urns.
