590 Gagnon Place, Newmarket, ON L3X 1V8

About this home

NEARLY 4,200 FINISHED SQ. FT. IN STONEHAVEN WITH A CHEF'S KITCHEN, 5 BEDROOMS & A PRIVATE 123 FT DEEP LOT! From the moment you enter, this home feels elevated in every sense, with soaring ceilings rising above a sweeping curved staircase, polished tile underfoot and rich hardwood carrying through beautifully proportioned principal rooms. Crown moulding, expansive windows and French doors into the dining room add architectural detail, while formal living and dining spaces feel made for candlelit dinners and special occasions. The magazine-worthy chef's kitchen pairs extensive white shaker cabinetry and quartz countertops with a statement range hood, high-end stainless steel appliances and an oversized contrasting island. It opens to the family room with custom built-ins and a gas fireplace, while sliding doors frame the landscaped backyard. A private main-floor office, well-appointed laundry room with garage access and powder room complete the level. The recently updated primary retreat feels more like a private wing, with custom built-in storage, an oversized walk-in closet and a renovated 5-piece ensuite with a freestanding tub, glass shower and double vanity. Three additional bedrooms and another full bath complete the second floor, while the finished basement adds a fifth bedroom, recreation room, extensive storage, bathroom rough-in and pre-wiring for speakers. The fully fenced backyard is framed by mature trees and established gardens, with a multi-level deck for outdoor dining. Notable updates and features include updated windows, newer air conditioning, a high-efficiency furnace, 200-amp service, central vac, an owned hot water tank and a water softener, all contributing to the quality that makes Stonehaven such a coveted Newmarket address.
