About This Home

450 State Route 146

Lovingly restored over decades of ownership, this remarkable 1880s Colonial seamlessly blends timeless character with thoughtful modern updates. Inside, you'll find a beautifully updated eat-in kitchen featuring brand-new quartz countertops, a stylish new backsplash, and updated appliances. The impressive great room addition (2007) is the heart of the home, boasting soaring cathedral ceilings, recessed lighting, a floor-to-ceiling stone fireplace, and ample space for entertaining. A custom bar with matching stone veneer creates the perfect setting for hosting family and friends year-round. The first floor offers flexibility with two bedrooms (one used as an office), a laundry room, a half bath, and a formal dining room. Upstairs, you'll find three additional bedrooms, each with its own en-suite full bathroom and walk-in closet, a rare and desirable feature. Step outside to your own backyard retreat, complete with in-ground pool (liner 2024 and pump 2026) and patio designed for relaxing and entertaining all summer long. The property backs up to Black Creek (flood zone free) adding to the charm and tranquility this home offers. Enjoy peace of mind with countless updates, including a brand-new heating system (2025), new electrical panel (2025), mini-split system for year-round comfort, updated windows, new flooring, and modern fixtures throughout. Enjoy the best of Guilderland living with nearby favorites like Indian Ladder Farms, Tawasentha Park, the Altamont Fairgrounds, local restaurants, and scenic trails. From weekend adventures to everyday conveniences, everything you love is right outside your door. This is a rare opportunity to own a true piece of history that is beautifully updated while preserving the charm and craftsmanship that makes this one-of-a-kind home so special!
