A Rare Executive Estate. Unmatched Privacy. Limitless Possibilities. Set on 5.76 acres of private, tree-lined grounds, this custom-built estate offers a secluded retreat just minutes from the GTA. Meticulously crafted by its original owners, the home perfectly balances architectural presence with everyday livability, delivering space, privacy, and quality that is nearly impossible to replicate. Step inside to a dramatic 22-foot foyer with a floating staircase, where floor-to-ceiling windows frame serene natural views and flood the home with sunlight. Designed for both grand-scale entertaining and family living, the heart of the home is a chef’s kitchen with dual oversized islands seating up to 14, premium appliances, and effortless flow to the sunroom and outdoor kitchen—perfect for gatherings year-round. Indulge in resort-style amenities: a private spa with a 10-person jacuzzi, steam room, and sauna, a fully equipped home theatre, gym, games area, and full bar, plus a private elevator for ultimate convenience. A three-bedroom guest suite above the garage offers flexibility for extended family, live-in support, or visitors. The outdoors is equally spectacular: heated saltwater pool, two fire pit areas, tennis and basketball courts, walking trails around a private pond, and multiple terraces for entertaining or quiet reflection—all in total privacy. Sustainably built with solar and geothermal systems, full smart-home integration, and dual septic systems, this estate blends luxury, efficiency, and enduring value. This is a rare legacy property offering privacy, land, lifestyle, and unmatched proximity to urban centers. Don’t miss your chance: View this extraordinary estate today. (id:23309)
