**Addendum**

Following an extensive multi-year transformation completed in 2024, this sun-filled home offers a thoughtfully reimagined layout featuring 5+1 bedrooms, 4.5 bathrooms, and a beautiful sunroom office, complemented by a sophisticated palette of natural materials and refined finishes.

The ambitious renovation included a substantial three-storey extension incorporating a rare three-car garage and expansive rear patio, excavation of the original basement to increase ceiling heights, and significant structural modifications. Exceptional attention to detail is evident throughout, from custom white oak cabinetry, herringbone white oak flooring, exquisite natural stone and marble finishes, and architectural ceilings details to bespoke lighting and integrated smart-home technology. Luxurious marble bathrooms with heated floors, an expansive primary steam shower featuring 11 water outlets, premium appliances, built-in audio, and thoughtfully designed living spaces combine sophisticated aesthetics with modern comfort and convenience.

The beautifully landscaped grounds are equally impressive, featuring manicured gardens, extensive privacy hedging, and a secluded backyard oasis centered around a year-round swimming pool. An oversized heating system allows the pool to heat quickly, even in winter temperatures, while a heated pathway from the home to the pool steps creates a unique Nordic spa experience at home.
