Presenting a truly rare offering in the heart of South Hill, one of Toronto's most established, architecturally significant, and tightly held enclaves. Moments from the private, gated avenue of Edmund Gate, 181 Poplar Plains Rd represents an extraordinary 67 x 144.64 ft landholding, a scale and presence seldom available in this supply-constrained luxury neighbourhood. Acquired in its entirety, the property offers the opportunity to create a landmark custom residence of approximately 7,600 sq ft above grade (subject to final approvals), allowing a purchaser to fully capitalize on the site's exceptional frontage, depth, and architectural potential. For those seeking flexibility, Committee of Adjustment approval has been secured for severance into two 33.5 ft parcels (181A and 181B Poplar Plains Rd). The proposed configuration supports approximately 3,800 sq ft above grade plus 1,600 sq ft below grade per residence (5,400 sq ft total), delivering meaningful scale for contemporary luxury homes in a neighbourhood where large-format new construction is exceptionally limited. Surrounded by mature canopy, estate residences, and enduring architectural character, this address offers privacy, prestige, and proximity, just moments to Summerhill, Yorkville, top-tier schools, transit, and the city's ravine network. A compelling acquisition for a builder pursuing premium infill. An exceptional canvas for an end user envisioning a generational legacy home in one of Toronto's most distinguished residential pockets.
