Architect, of Belfast and Dublin. Thomas Duff entered the office of YOUNG & amp; MACKENZIE circa 1872 and after completing a four-year pupilage, continued in the practice for a further three and a half years as an assistant. He left in 1880, recommended by his employers as being 'an excellent draughtsman and well up in preparing perspectives and pen and ink etching'.(1) In 1876, he had been awarded a first prize in a competition held by the Belfast Architectural Association.(2)
Duff subsequently moved to Dublin. In 1882 he wrote a letter to the Irish Builder about its gate lodge competition from lodgings in 14 Nelson Street.(3) Later in the year he was placed second in another of the journal's competitions with a design for a mortuary chapel.(4) He was still at this address in April 1883 when he published a design by himself for a gate lodge 'near Dundalk' in The Architect.(5) and when he exhibited a drawing of the Charters Memorial Schools, Belfast, at the Royal Hibernian Academy in the same year.(6) A perspective view by him of GEORGE COPPINGER ASHLIN' s Annemount, Co. Cork, was published in The Architect in 1884.(7)
