During the following 40 years, he won competitions and commissions for a wide variety of buildings including for the 1901 Glasgow International Exhibition, of which his Sunlight Cottages are the sole remains; in 1901 for the Glasgow Royal Infirmary, which resulted in a bulky and unpopular baronial-style design; and in 1904 for the Glasgow & South Western Railway's Turnberry Hotel. He undertook significant work for the Caledonian Railway at this time, including extensions to Glasgow Central Station and its hotel (1900–1905), Wemyss Bay railway station (1903), with its circular booking office and curving timber walkway to the steamer pier, and Stirling railway station (1915), also with circular elements. He designed the Govan memorial church to Margaret Macgregor.
