Architect. Born in Edinburgh and educated at George Watson's College and the College of Art in the city. He was an apprentice under Sir Edwin Lutyens and worked with Sir Basil Spence in the Edinburgh-based architectural practice of Rowand Anderson and Paul. In his work, Kininmonth mixed a modern style with Scottish vernacular. Examples of his buildings are Adam House in Chambers Street (1954), the Mary Erskine's School at Ravelston (1966) and Holland House (1959), the first of Edinburgh University's Pollock Halls, built in the shadow of Arthur's Seat. He lived nearby in Dick Place.
Kininmonth was knighted in 1972 and awarded an honorary degree by the University of Dundee in 1975.
