Rarely does a property of this caliber hit the market - a designer transformed 3+2 bedroom, 3 bathroom masterpiece that feels like a true 5-bedroom home in beautiful Alderwood. Situated on a large 43' x 137' lot with over 3000 sqft of living space, it offers a scale of luxury and privacy that narrower lots simply cannot match. This "one-of-a-kind" residence features inspiration and design by a celebrated Canadian artist. The interior is highlighted by soaring 8 ft ceilings vaulted to 9 ft on the main floor, accented with natural wood details and wire-brushed wide plank oak flooring. At the heart of the open-concept main floor sits a stunning chef's kitchen equipped with a 36" 6-burner Bertazzoni range, a 66" Frigidaire Professional side-by-side refrigerator, and a massive quartz island. Each of the three bathrooms is curated with its own unique character; the primary ensuite is a west-facing sanctuary with Stelpro heated floors and a rain shower, while the main 4-piece bathroom impresses with a concrete double sink and heated Italian Terrazzo porcelain flooring. The bright lower level functions as a true extension of the home with impressive 8 ft ceilings, a gas fireplace, and custom millwork. The home is mechanically superior with a high-efficiency Bosch boiler and Daikin AC system. Beyond the double-car garage, the property boasts an oversized, fully insulated backyard studio with electrical power, offering an ideal home office or potential garden suite conversion. Perfectly positioned near the great schools, parks, Long Branch GO Train and major highways. 18 Treeview Drive is the definitive choice for a family seeking space, style, and a premier location.
