Exciting Development Opportunity in Uptown Waterloo’s Sought-After Mary Ellen Neighbourhood! This prime property offers unparalleled potential in one of Waterloo’s most desirable locations. Situated on a generous lot extending from Mary Street to Dodds Lane, it features dual access—a rare find that opens up endless possibilities. Whether you envision building a luxurious single-family home with a spacious rear garage or capitalizing on the incredible development potential, the choice is yours. With the City of Waterloo now permitting up to four units per semi-detached lot, this property can potentially accommodate up to eight residential units (buyer to verify with city planning). Located just one block from King Street, this property is steps away from the vibrant heart of Uptown Waterloo. Enjoy boutique shopping, fine dining, entertainment, and more—all within walking distance. Seize this rare opportunity to create something extraordinary in an unbeatable location. Whether for personal use, investment, or development, the possibilities here are truly exceptional. Please note: 223 Mary Street and 9 John Street currently share a merged title, but the seller will apply for a technical severance, ensuring each property will have its own separate lot and title. The proposed boundary line has been outlined (see photos for reference).
