About this property

Exquisitely finished modern mansion in prime Thornhill, fully renovated top-to-bottom with sophisticated, high-end detailing throughout. The interior showcases a dramatic foyer and great room with soaring 21+ ft cathedral ceilings, enhancing light and volume, while 24" x 24" Crema Marfil limestone slabs flow seamlessly across the main level. A custom walnut kitchen is appointed with Caesarstone countertops, premium built-ins, and top-tier appliances including Sub-Zero fridge, Miele dishwasher, and Wolf cooktop with hood fan. A striking three-level floating staircase with wrought iron railings serves as a central architectural feature, complemented by three fireplaces and a refined private office with natural wood cabinetry. The primary suite offers a tranquil retreat with its own balcony, while all washrooms and the lower level have been fully renovated to a fresh, modern standard. California Closets provide tailored organization throughout. The exterior completes the offering with a private backyard oasis featuring a Betz concrete pool, waterfall, hot tub, Credit Valley flagstone, interlock driveway, and a full sprinkler system, ideal for both relaxation and upscale entertaining.

What can you build here?

Lot dimensions: 30.5 m x 55.5 m (100'-0" x 182'-0")

A fourplex is as-of-right on nearly any detached lot in the GTA, and many go further, a sixplex in the right ward, a garden suite, or a two-lot severance. Whether the numbers work comes down to the zone, the overlays, and the parcel, which is exactly what a TESA development read tells you. Get one on this lot before it goes.
