Over the course of his career as a custom home designer, David Small has done everything from Arts and Crafts bungalows, to Cape Cod cottages to a French Provincial chateaux. But when the time came to design a home for his wife and their twin daughters, he took a chance on modernism. The Prairie Style ideas of Frank Lloyd Wright are evident in the overhanging eaves of the strongly horizontal roofline capping each tall exterior wall, and the clerestory windows high up the double-height walls of the open-plan dining area. At the heart of the interior is a fireplace of limestone and a hearth made from a huge chunk of the Canadian Shield quarried in Ontario’s French River district. Mr. Small has delivered a relaxed design that is directly modernist but without the sharp edges some think of when hearing the words “modern house”.
