THE LEGACY AT OLD COLONY Inspired by Frank Lloyd Wright's philosophy of organic architecture, this exceptional residence brings together timeless design, natural materials and a deep connection to its surroundings. Strong horizontal lines, expansive walls of glass, rich wood and stone, and a seamless relationship between interior and exterior create a home of rare scale, warmth and architectural presence. Set amid beautifully landscaped grounds and mature trees, the estate is designed for a life well lived. Expansive terraces extend the living space outdoors, while a professional tennis and multi-sport court, dedicated wellness spa, wine cellar and tasting room, gallery walls, and professional home theatre offer a remarkable setting for recreation, entertaining and quiet retreat.At its centre, the Cameo kitchen is both beautifully composed and highly functional, complemented by generous gathering spaces and private bedroom suites with refined ensuites and separate dressing rooms. Throughout, natural light, thoughtful proportions and carefully selected finishes create an atmosphere that is elevated yet entirely livable.Ideally positioned in one of Toronto's most sought-after residential enclaves, this private estate is moments to the Granite Club, Toronto Cricket & Curling Club, Donalda Club, Rosedale Golf Club and Bayview Golf & Country Club. Yorkville, Bayview Village, York Mills and Shops at Don Mills offer exceptional dining and shopping, while leading independent schools, major highways, downtown Toronto, private aviation and Pearson International Airport are all within convenient reach.A distinctive architectural offering for those who value privacy, design and an exceptional way of living. A World of Magnificence Awaits....
