About this property
A brilliant celebration of light, space, and architectural innovation, this extraordinary four-level estate spans over 5,500 sq. ft. of custom finished living space. Over $1M was spent transforming the interior redesign. Dramatic stacked fireplaces in slate, copper, and stainless steel connect a 20-foot-high office to a vaulted loft overlooking treetops with skyline views as far as Mississauga City Centre. Chef's kitchen features Imperial Green granite, two Sub-Zero fridges, new induction stove, an integrated island dining table, a 3-tier coffee bar and a walk-out to a glass-railed balcony with built-in BBQ. Ten skylights, bay windows, and an 18-light chandelier bathe the house with light. The home offers 4+1 bedrooms and 6 bathrooms, including vaulted ceilings in two bedrooms and a mini-loft in a third bedroom. Natural cherry, maple, and purple heart flooring includes design inlays that connect the bedrooms. Walk-out lower level includes an in-law suite, recreation/gym area, great storage, and a 48-bottle wine rack. Backing onto a lush ravine and its meandering Mullet Creek, the stunning $500K landscaping harmoniously merges the property with greenery beyond its glass fence. Exterior features include hand-cut limestone walls, stone pathways, and an outdoor oasis that has a 32'x10' heated saltwater pool, retractable safety cover, waterfalls, water shear, and a three-season Lanai with gas fire pit and Phantom screens. This unique home offers turn-key luxury living in prestigious Sawmill Valley, steps to top schools, trails, parks and Credit Valley Hospital.
