Career
Calvert"s work appears to have been exclusively confined to Edinburgh, and was mostly concerned with the creation of Baronial tenements (particularly in Marchmont) and villas in the Second Empire and Jacobean styles. He is responsible for a varied selection of villas on or in the vicinity of Colinton Road in Merchiston. One of these was for many years the home of author Dorothy Dunnett.
He is also known to have designed modifications for at least one New Town building, in Abercromby Place, in 1899.
He trained as an architect under Frederick Thomas Pilkington and is known to have worked on jobs relating to the Cowan Brothers, paper-makers in Penicuik. Much of his work (especially in Marchmont) shows strong stylistic influence from Sir James Gowans.
He died at his home, 80 Willowbrae Road, Edinburgh and is buried in the Grange Cemetery.
