Nestled along one of Glens Falls' most distinguished residential streets, this stately circa-1910 residence offers a rare blend of timeless architectural character and modern infrastructure. Set on nearly an acre, the home encompasses 4,864 square feet with six generously sized bedrooms, four bathrooms, and exceptional living spaces designed for both grand entertaining and everyday living. Rich in original craftsmanship, the home showcases an elegant staircase, soaring ceilings, detailed millwork, abundant natural light, and original hardwood floors beneath much of the carpeting. A comprehensive mid-1980s renovation modernized the electrical, plumbing, and heating systems, an uncommon advantage for a home of this era. Three of the four bathrooms have since been tastefully updated. Occupying the entire third floor, the expansive primary suite lives like a private penthouse, featuring a massive bedroom, walk-in closet, en-suite bath, and its own dedicated HVAC system for year-round comfort and privacy. The flexible floor plan offers multiple formal and informal gathering spaces, a rear staircase leading directly to the second-floor laundry, and outstanding versatility for entertaining, working from home, or multigenerational living. The heating system features eight independently controlled zones and a redundant boiler configuration for added efficiency and reliability. Outside, mature landscaping and nearly an acre of beautifully maintained grounds provide an uncommon sense of privacy just moments from downtown Glens Falls, parks, restaurants, shopping, and cultural attractions. Beautifully maintained, thoughtfully updated, and ready for its next chapter, 542 Glen Street presents a rare opportunity to own one of Glens Falls' truly distinguished residences.
