Brian MacKay-Lyons has evolved an architecture out of the vernacular of his native Nova Scotia that combines simplicity of form and construction with a subtlety of placing a house on its site. In three recent houses, the expansiveness of the structures has increased and the landscape has become more integrated with the interiors, physically and visually. Both extremely rational and highly idiosyncratic, MacKay-Lyons' work shows how rootedness in a place, however geographically isolated, can result in architecture as rigorous as that produced anywhere.
