403 des Seigneurs presents a rare, design-advanced ground-up development opportunity in one of Montréal’s most active residential submarkets — Griffintown / Petite-Bourgogne, in the borough of Le Sud-Ouest. The project is at the permit-application stage, with a complete architectural drawing set prepared by FRW (Fischer Rasmussen Whitefield Architectes) and design development substantially advanced, offering a buyer, investor, or developer a shovel-ready path to market with materially reduced pre-development risk and timeline.
