Set on a quiet crescent just steps from the lake, this Grimsby home offers the peaceful and established lifestyle buyers are searching for. Inside, over 2,300 sq. ft of well-designed living space delivers both comfort and versatility. The main floor welcomes you with a grand, airy entrance and soaring ceilings. At the heart of the home, a spacious kitchen with large island and breakfast bar overlooking the family room with gas fireplace and walkout to the bonus sunroom, creating the perfect backdrop for summer dinners, morning coffee, or a cozy reading retreat overlooking the rear yard. A separate open concept living and dining area provides space for entertaining, celebrations, or quiet evenings in. Also included on this level is main floor laundry, inside entry to garage, and guest half bath. Upstairs, a thoughtfully laid out upper level offers three generously sized bedrooms, including a private primary retreat overlooking the backyard, complete with a walk-in closet and a spacious 5 piece ensuite with separate shower and soaker tub. Two additional bedrooms share a large main bath, with ample storage throughout. The lower level is a blank canvas, with excellent potential for a recreation room, home gym, office, or additional living space. With thoughtful updates and worry-free maintenance already completed, including full interior painting (2026), heat pump (2023), washer and dryer (2020), and shingles (2019), this is a move-in-ready opportunity to enjoy a refined home in an exceptional lakeside neighbourhood. Located in one of Grimsby’s most sought-after neighbourhoods, you’re a short walk to Lake Ontario, waterfront parks, and scenic trails, while still enjoying quick access to the QEW for an easy commute to Niagara or the GTA. It’s a setting that perfectly blends nature, convenience, and community.
