Welcome to this grand early 20th-century Colonial estate - an exceptional offering on one of West Mount Airy's most coveted park blocks. Set on nearly an acre and bordering the Wissahickon, the home combines timeless stone architecture with thoughtful renovations by a noted architect, showcasing custom detailing throughout.Behind the tree-lined frontage, privacy and serenity unfold with stone terraces, mature gardens, and a sparkling saltwater pool - all just minutes from the shops and restaurants of both West Mount Airy and Chestnut Hill. Inside, three levels (plus basement) offer over 5,000 square feet of living space with five bedrooms, five full baths, and a powder room. The gracious entry foyer with its curved staircase sets the tone, leading to a formal living room and dining room - each anchored by Mercer tile fireplaces. A sun-filled gourmet kitchen opens to a glass-wrapped sunroom with new French doors, alongside a den, mudroom, and powder room. The second floor hosts three en-suite bedrooms, a bonus room, a laundry room, and an additional full bath. The third floor offers versatility: a guest apartment or family retreat with two bedrooms, a living area, office, and full bath. Additional highlights include a full unfinished basement and a two-car garage. This is a home that balances classic grandeur with modern livability - a private retreat on the Wissahickon, yet seamlessly connected to all the best of Philadelphia.
