A Contemporary Expression of Refined Family Living. Welcome to 176 Rumble Avenue, an exceptional custom-built residence set within the coveted Mill Pond community of Richmond Hill, an address where timeless neighbourhood appeal meets sophisticated contemporary living. From the moment of arrival, the residence makes a distinguished impression, with an impressive architectural presence and a dramatic 21-foot grand foyer establishing a sense of scale and elegance. Inside, approximately 5,000+ square feet of beautifully appointed living space unfolds across three levels, designed for both grand entertaining and effortless family living. The principal living spaces are defined by 11-foot ceilings, expansive proportions, premium engineered hardwood flooring and an open-concept design that creates a natural flow from one room to the next. Skylights introduce additional natural illumination, while integrated sound and carefully considered construction details elevate both comfort and everyday living. The heart of the home is an impressive contemporary kitchen with generous proportions and a center island, complemented by sophisticated principal rooms and a dedicated office. Upstairs, the private bedroom level features four generously proportioned bedrooms, including an expansive primary retreat with walk-in closet and luxurious ensuite, while the second floor is enhanced by 9-foot ceilings and convenient bedroom-level laundry. The lower level introduces an entirely different dimension of versatility. With 10-foot ceilings, heated floors, a second kitchen, living area, bedrooms and a separate entrance, it provides an exceptional environment for extended family, guests, a private retreat or additional lifestyle space.
