Description

Set on a deep pool-sized lot in prestigious South Oakville, this custom-built estate offers approx 8,500 sq ft of meticulously finished living space. Upon entry, a striking foyer framed by a dramatic slab feature wall and oversized entry door introduces interiors rich in architectural detail, soaring ceilings, wide-plank oak flooring, and oversized windows and doors that blur the line between indoors and out. The designer kitchen is both unforgettable and a chef's dream, showcasing state-of-the-art built-in appliances, an oversized island, quartz and natural wood surfaces, custom cabinetry, a full prep pantry, and dedicated servery. Expansive principal rooms are flooded with natural light, while the stunning family room features a statement fireplace wall and seamless access to private outdoor living spaces. A spectacular 22-ft office/library creates a sophisticated work-from-home experience. The second level is anchored by a luxurious primary retreat complete with fireplace, custom walk-in closet, and spa-inspired ensuite with heated floors and freestanding tub. Spacious secondary bedrooms offer ensuite or semi-ensuite access, while the versatile third-floor loft functions beautifully as a private guest retreat, executive lounge, studio, or additional bedroom complete with wet bar, walk-in closet, and ensuite. Newly finished, the lower level delivers a true lifestyle experience featuring multiple entertainment lounges, a designer wet bar/kitchenette with walkout access, theatre/games room, sauna, wine cellar, guest suite, spa-inspired bath with double rainfall shower, and a newly installed elevator servicing all floors. Modern design and exceptional comfort converge with multiple fireplaces, built-in speakers, a pet washing station, landscaped backyard, and walkout access to multiple private decks. Moments from reputable schools, boutique shopping, private clubs, Lake Ontario, Bronte Harbour, and convenient access to the QEW and Hwy 403.
