Property Description

This architectural masterpiece offers 7,000 sq. ft. of luxurious living space with 4+2 bedrooms, 6 bathrooms, an incredible resort-style backyard oasis, and a fully finished basement with separate entrance. Set on an 85 x 135 ft. lot in a mature Ancaster neighbourhood, just one minute to highway access and all Power Centre amenities, this dream home impresses with striking curb appeal, professional landscaping, and an oversized triple garage with 14 ft. ceilings and two car lifts. The grand foyer with a soaring 21 ft. ceiling and curved staircase opens to a sophisticated interior featuring bold millwork, expansive porcelain, and wide-plank hardwood all illuminated by massive windows allowing plenty of natural light. The main level boasts formal living and dining rooms with 12 ft. ceilings, a private office, powder room, mudroom, and a gourmet eat-in kitchen with top-tier appliances. A 4-season sunroom with radiant in-floor heating and a family room with 11 ft. ceiling and stone fireplace create the perfect entertaining spaces. Upstairs, the sensational primary suite includes custom built-ins, spa-inspired 5-piece bath, private balcony, walk-in closet, and a custom dressing room fit for any wardrobe. Three additional bedrooms, all with ensuite baths (heated floors), and bedroom level laundry complete the upper level. The finished lower level offers a recreation area, home theatre, 2 bedrooms, full bath, second laundry, and kitchenette—ideal for family enjoyment or a multigenerational in-law suite. Step outside to a private resort-style retreat with heated saltwater pool (waterfalls, lights, fire features), sunken hot tub, outdoor kitchen with pizza oven, extensive hardscaping, artificial turf, storage shed, and an elite K-Array sound system. Upgrades include Control4 automation, integrated security with cameras, whole-home sound, and dual furnaces, A/Cs, and HRVs for comfort and efficiency.
