Designed by noted Morristown architect Robert C. Walsh (Morris County Golf Club) for famed engineer Daniel E. Moran, the home reflects a rare level of architectural significance. Set on four private acres and surrounded by the protected beauty of the India Brook Preserve, the property offers exceptional privacy and a true estate setting. Inside, mahogany carved woodwork spans both the first and second floors, while grand-scale public rooms evoke a bygone era of elegance and craftsmanship. A distinctive ante room, leading to the dining room, features wood paneling sourced from a ship's quarters, and a discreet secret door off the receiving room adds a touch of character and intrigue. Sunlit piazzas with walls of windows overlook the preserve, seamlessly connecting indoor and outdoor living. A 2021 kitchen updated balances classic design with modern function, featuring a Wolf gas cooktop, two electric wall ovens, stainless refrigerator/freezer, dishwasher, and a butler's pantry with beverage fridge and wet bar for effortless entertaining. The grounds include a Har-Tru tennis court and a blend of open and wooded landscape of preserved land. Do not miss the opportunity to own a legacy Tudor estate in Mendham with history, character, and enduring appeal.
