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. A rare opportunity to
own one of Ancaster's most extraordinary residences!
