Le 205 is a minimalist house located in Montreal, Canada, designed by Atelier Moderno. A designer, his two sons, and their tireless terrier Winston share a small 1950’s building that stands rather unnoticed among its neighbors in the Mile-Ex district. The robust walls of this former workshop, however, hide a jewel conversion within. If the recomposed facade is surprisingly private, its large windows and full-height steel door, slightly recessed, announce the minimalist mastery of the interior plan: a wide corridor extends along the north-south axis, adjacent an existing party wall of exposed masonry accentuated by a thin line of light, serving well-defined living spaces, bright and convivial, where everyone can go about their activities without affecting those of others, all the while fostering a certain air of intimacy and affection.
