About the Property

An extraordinary estate, The Devlin Estate, is set within 38.25 private acres in the rolling countryside of Glenelg, Maryland, United States. Envisioned as one of the most ambitious private residences in the Mid-Atlantic, this ultra-luxury property spans nearly 2,973 square meters and is framed and enclosed, offering a rare opportunity to complete a world-class residence without the years of planning typically required. The architectural drama of the estate is defined by soaring two-story spaces and walls of windows capturing pastoral vistas. A sculptural floating spiral staircase connects three expansive levels, enhancing the grandeur of the main floor designed for both living and entertaining. This level features dual kitchens, expansive gathering areas, and a stately library suited for quiet work or private meetings. The upper floor houses a spectacular two-story primary suite, complete with separate spa-inspired bathrooms and extraordinary dressing areas, including a dramatic two-story closet. Eight generously sized bedrooms provide luxurious accommodations for family and guests. The lower level serves as a destination for recreation and entertainment, featuring a private bowling alley, a dedicated theater room, and multiple flexible spaces ready to become a wellness suite, wine gallery, studio, or additional guest quarters. Outside, the estate’s scale continues across its 38.25-acre setting, offering exceptional privacy and sweeping countryside views alongside the home’s high-efficiency geothermal infrastructure for sustainable living. Location: - Convenient access to the Baltimore–Washington corridor via Interstate 70 and Interstate 95 - Proximity to major employers such as Johns Hopkins University and the National Security Agency - Upscale shopping, dining, and entertainment await in nearby Columbia - Outdoor enthusiasts will appreciate proximity to scenic escapes like Patapsco Valley State Park Price: €4,358,210 including fees (paid by the seller).
