However, the practice continued to find work, with J M Dick Peddie's designs including the Bank of Scotland's George Street branch (1883–1884).
Kinnear worked on the practice's major schemes during the early 1880s, including Longmore Hospital and Craiglockhart Hydropathic, but in 1884 he became Colonel of the Midlothian Coast Artillery Volunteers, and his role in the firm reduced.
He died suddenly in 1894, and within a year or two Peddie had taken on George Washington Browne (1853–1939), with whom he had worked informally for some time, as a partner.
His contribution to the design work of his practices is increasingly obscure after this point, with greater reliance placed on carefully selected junior designers, often recruited from the Edinburgh School of Applied Art, which became part of Edinburgh College of Art in 1907.
These included his assistant James Forbes Smith, who Peddie took on as junior partner in 1909, an association which lasted until 1917, by which time the practice had limited work.
