They obtained their first commission from Steedman's dentist in 1952, while still in their final year at ECA. The resulting house, Avisfield, at Cramond (1957) was listed at category B in 2007, as one of the first modern-movement houses to be built in Scotland. Their second house, at Kevock Road, Lasswade, was built on a narrow site above the River North Esk. The narrow site required the building to be cantilevered over the slope. The Sillito House on Blackford Hill followed in 1959, with the main living space placed on the first floor to take advantage of views across Edinburgh. By 1970 around 15 houses had been completed, including Morris' own house at Fala (1970), and Steedman's in Ravelston (1960), as well as the Principal's House at the University of Stirling (1967), which was listed at category A in 2009.
