Lochbourne - Woven into the very fabric of Upper Nyack, Lochbourne is one of the original “Barons of Broadway” mansions. Built circa 1865, this extraordinary residence remains a living testament to its remarkable past - as a summer retreat for the affluent, home to noted luminaries, and historical accounts suggesting it may have been a stop on the Underground Railroad. Unparalleled architectural integrity and craftsmanship virtually unchanged for over a century and a half. From the moment you step onto the gracious covered veranda, you are transported to another era. The grand entry foyer welcomes you with a sweeping staircase and an immediate sense of scale. Throughout the home, rich chestnut woodwork and exquisite parquet floors create warmth, depth and timeless elegance. Designed for both formal entertaining and comfortable living, the layout has exceptional flow and grandly proportioned rooms. A spectacular front-to-back living room/library spans the entire south side of the house, filling the space with natural light. Pocket doors open to the dining room, parlor, sitting room and playroom, allowing for intimate gatherings or large celebrations. An enclosed sunroom and a butler's pantry - complete with back staircase - enhance the charm. On the second floor you will find five bedrooms including a truly magnificent primary bedroom with an 18-foot cathedral ceiling, and one bedroom with its own private balcony overlooking the backyard. Two full baths round out the second floor. The third level offers remarkable versatility with a large great room/media room, two additional bedrooms, a den and a full bath - ideal for guests, au pair or just extra living space. A special bonus is the carriage house with a double-height, three-car garage offering tons of uses - art studio, home office or whatever you choose. Set on 2.18 acres of lush grounds, the property provides privacy and room to breathe. This gracious estate is in need of updating and provides a rare opportunity for the next steward to thoughtfully restore and reimagine this architectural treasure. With vision and investment, this grand mansion can once again shine at its full brilliance. A truly special opportunity to restore one of Upper Nyack's most significant homes.
