Welcome to Penthouse 10 at 15 Grenville Street - a rarely offered, calm, contemporary retreat above Toronto's urban core. Step through floor-to-ceiling glass to a remarkable terrace that opens to pure sky - no ceiling, no shadows, just panoramic city views and quiet air far above the street. The contrast is striking: steps from the pulse of Yonge & College, yet tranquil and still once inside. A thoughtful interior pairs clean design with practical luxury, open-concept layout, and floor-to-ceiling light amplify the sense of calm. Here, morning coffee comes with horizon views; evenings stretch out under open air. An address that anchors you in the Bay Street Corridor - minutes to U of T, Ryerson, Financial District, subway & Queen's Park. Includes heat & water & building insurance covered in monthly fees. A penthouse designed not to impress, but to soothe.
