An absolute standout in the East Riverdale community, this 4-bedroom home has undergone a total professional transformation that offers the caliber of a custom new build. Backing directly onto the park for ultimate privacy and greenery, 103 Harcourt Avenue was meticulously rebuilt from the inside out (2021-2024) with full permits and ESA certification, providing complete peace of mind in a historic neighborhood. The main level is designed for seamless entertaining, flowing from a spacious dining area through a showstopping chef's kitchen-featuring a massive10-foot Caesarstone island and premium JennAir appliances-into a sun-drenched family room with a tucked-away powder room off to the side. This living space is anchored by custom built-in sand a massive wall of windows that make the room feel entirely open to nature, with direct access to an expansive back deck and a rare, large backyard that flows perfectly for indoor-outdoor living. Solid oak stairs with handcrafted metal railings lead to the second level, which hosts two good-sized bedrooms, a 4-piece family bath, and an additional impressively large bedroom. The entire third floor is dedicated to a massive primary retreat featuring a large spa-like ensuite, "His and Hers" custom closets, and designer finishes. Mechanically, this home is in a league of its own: a new roof (2024), 100% new plumbing and electrical, a high-velocity zoned HVAC system for floor-by-floor climate control, and a Lifebreath HRV for superior air quality. The high-ceiling basement features a separate entrance and design drawings for future development. Located in the coveted Frankland School catchment and just steps from the Pape subway station (the future Ontario Line hub), this home offers unmatched connectivity and long-term value, all within walking distance to Withrow Park and the vibrant shops of the Danforth.
