    What this listing tells us

    Property description

    Improved price! Welcome to 10 Thairs Ave nestled in the prestigious and highly sought-after Woodruff Estates community, one of St. Catharines most desirable neighborhoods. Just steps from Montebello Park, this beautifully updated 3-bedroom, 4-bathroom home offers the perfect balance of timeless charm and modern luxury. Reimagined between 2019 and 2020, no detail was spared in its transformation, making it an exceptional blend of character and contemporary upgrades. Inside, you'll discover a thoughtfully renovated kitchen, updated bathrooms, and generously sized rooms that are ideal for both family living and entertaining. The abundance of windows floods the home with natural light, creating a warm and inviting atmosphere throughout. The formal living room, featuring a gas fireplace and a rebuilt mantle, adds sophistication and charm. A brand-new gas boiler, recently installed (spring 2025), ensures comfort and energy efficiency for years to come. The stunning garden/family room, added in 2019, opens up to a lush, private backyard, your own retreat in the city. The beautifully landscaped gardens are perfect for relaxing, entertaining, or cultivating your green thumb. Upstairs, the home features three generously sized bedrooms, two with its own ensuite bathroom and ample closet space. A staircase leads to the third-floor attic, offering abundant storage space or the potential for additional finished living area. Families will love the proximity to top-rated schools, while commuters will appreciate the easy access to the 406 and QEW. Move-in ready with endless potential, this home offers both style and practicality in one of St. Catharines' most beloved communities.
