The Patenaude House (1723) -- A Heritage Gem in Old Longueuil A sublime heritage stone home built in 1723, set back from the street on a lot of over 13,000 sq. ft. An impressive amount of renovation work carried out with quality and respect for its original character: renovated kitchen, bathroom and powder room, grading, landscaping, paved driveway and a geodesic greenhouse. Calm and refinement, close to all services and just minutes from Montreal. A true gem to discover without delay.
