About this home

Known as "Glenowre," this distinguished 1906 south-facing Tudor estate offered for the first time in 50 years blends historic pedigree with refined modern living. 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.
