591 Plantation Gate, Newmarket, ON L3X 2C2

Former model home in Summerhill Estates. This 4-bedroom detached two-storey offers over 2,700 square feet above grade on a landscaped, fenced 39x109 foot lot in one of Newmarket's most established family neighbourhoods. The layout works for both everyday family life and entertaining. The eat-in kitchen walks out to the patio and overlooks a hardwood family room, and main-floor laundry with direct garage access keeps the day-to-day easy. Pot lighting and crown moulding run through the main level, and a skylight above the circular staircase fills the home with natural light. Upstairs, four generous bedrooms include an oversized primary retreat, 18'8" 16'1", with a walk-in closet and 4-piece ensuite. Here's what sets this one apart: two separate staircases reach the unfinished lower level, one straight from the garage, with a rough-in bath already in place. That's clear in-law suite potential for a buyer who needs multigenerational space. Move-in ready, with the big-ticket items already done - furnace, tankless water heater, and shingles all about six years old, plus a 200-amp panel. Walk to Mulock Park, with quick access to transit, schools, highways, and Main Street amenities.
