99 Birch Avenue, Richmond Hill, ON L4C 6C5

Rare offering in coveted community of South Richvale. This custom full stone two storey sits on a 1. 33 acre ravine lot at the end of a gated, dead-end cul-de-sac with total privacy. Held by its original owner and built with superior construction materials, the home offers 3,722 square feet above grade plus a bright finished walk-out lower level, four bedrooms, five bathrooms, and an elevator serving all three levels as well as the garage. Entertaining-sized principal rooms span the of the home, each framing the ravine: separate formal living and dining rooms, a main floor office, and a family room anchored by a floor-to-ceiling stone fireplace. The centre-island kitchen walks out to a terrace over the trees, with a sunny private breakfast area and southern exposure. Custom walnut hardwood floors, nine-foot smooth ceilings, custom cornice mouldings, a large skylight, and a sculptural floating oak staircase rising from the lower level to the second storey. The primary retreat offers a sitting area, walk-in closet, spa-inspired ensuite, and a private balcony over the ravine. A second bedroom enjoys its own four-piece ensuite, and all secondary bedrooms are generously sized. The walk-out lower level offers space to create a full in-law suite built for multi-generational living: an oversized living and dining area, second kitchen, sauna, wine room, abundant storage, and two walk-outs to a covered patio over the ravine. The setting is the rarity. A wrought iron gated entrance opens to an oversized interlock driveway. The home backs onto your own private ravine that cannot be severed or developed, steps to nature trails, minutes to highways and commuter routes and access to top private schools.
