1 Blythswood Square, Glasgow

Classical three-storey and basement terrace block of three-bay houses, built around 1829. No 5 has a stylised Art Nouveau inset pedimented doorpiece by Charles Rennie Mackintosh.

The main frontage of the building is 21 bays long with outer three-bay sections raised and breaking forward with fluted Ionic porticos. The ground floor central section has arched entries.

All entries to Blythswood Square have stairs oversailing a basement area. Windows are mainly sash and case in architraves, some with 12-pane glazing. The ground floor windows are set in recessed arches with moulded cills and aprons. Basement and 1st floor cill band. 1st floor windows corniced. Eaves cornice and blocking course. Spearheaded cast-iron railings. The seven-bay returns to Douglas Street and to Blythswood Street largely repeat the main elevation detailing.

There is a rendered addition to the rear of No 5 Blythswood Square in Bath Lane with five-light timber mullioned and transomed stained glass window with wrought iron Art Nouveau grille.

Nos 2, 3 and 4 were redeveloped behind the principle elevation in 1987. Some interior work was reinstated following the rebuilding behind the façade.
