Set within one of Toronto's most prestigious west-end enclaves, 78 South Kingsway presents a striking custom residence backing onto the lush surroundings of the Humber River. This 4+1 bedroom, 5-bathroom home spans approximately 3,700 SF and embodies modern sophistication with timeless appeal. The interior reveals itself with intention. Sunlight filters through a dramatic overhead skylight, illuminating wide-plank engineered oak floors and a sculptural oak staircase framed by glass. Every element has been carefully considered, from tailored millwork to integrated technology, including built-in speakers powered by a Sonos system, smart lighting, and automated blinds. Prodigious principal rooms are designed for both comfort and entertaining, featuring expansive windows and a statement chef's kitchen that anchors the main level. The kitchen features a quartz waterfall island at centre stage, complemented by a suite of Thermador appliances, and opens effortlessly onto a raised deck, creating a seamless transition for indoor and outdoor entertaining. The upper level is thoughtfully composed with four generously scaled bedrooms, each with access to ensuite baths with electric heated floors. The primary suite offers a quiet retreat, complete with a private balcony, dual walk-in closets, and a spa-inspired ensuite with a freestanding tub, glass shower, and double vanity. A dedicated laundry room adds practical convenience. Below, the walk-up lower level introduces a flexible extension of the home, featuring a spacious recreation area, wet bar, fifth bedroom, and a well-appointed bath, suited for guests, extended family, or income-generating potential. Outdoors, the landscaped grounds unfold into a private backdrop with no rear neighbours. A custom deck with integrated lighting and audio enhances the setting, offering a peaceful escape framed by nature. Positioned moments from top-rated schools, Bloor West Village, High Park, and the Humber River Recreational Trail.
