A new home by Toronto architect Ian MacDonald in the Georgian Bay resort community of Collingwood. Too many homes in non-urban Ontario riff off traditional farm buildings, silos, milking sheds, but not this one. Its architectural vocabulary is entirely modernist, its atmosphere quietly rich and complex, free from even a hint of farm. Designed to fit its site by Mr. MacDonald for a pair of Toronto lawyers and their two small children, the 3,400-square-foot weekend residence responds to all that is around it.Tom Arban
