In 1897, work began on a new building nearby to house the school on Renfrew Street, funded by a donation of £10,000 from the Bellahouston Trust, left from the will of Moses Stevens of Bellahouston. The building was designed by Charles Rennie Mackintosh, chosen for the commission by the school's director, Francis Newbery, who oversaw a period of expansion and fast-growing reputation. The first half of the building was completed in 1899 and the second half in 1909.
