Clarke & Bell & R. A. Bryden was a major Scottish architectural firm based in Glasgow, created by (1809–1889), (1814–1887) and Robert Alexander Bryden (1841–1906) around 1875. The practice dissolved in 1902, but several of their designs are now listed buildings. Bryden was again running his own practice, behind a glazed door within the Clarke & Bell office, by the time of the partnership's dissolution in 1902. That year, he and his son, Andrew, went into partnership and moved out of the Clarke & Bell office, by which time was at 212 St Vincent Street in Glasgow, and into 147 Bath Street.
