An extraordinary opportunity awaits at The Devlin Estate—an ultra-luxury legacy property at 15125 Devlin Drive set on 38.25 private acres in the rolling countryside of Glenelg. Envisioned as one of the most ambitious private residences in the Mid-Atlantic, the nearly 32,000-square-foot estate is already framed and enclosed, offering a rare chance to complete a world-class residence without the years of planning typically required. Architectural drama defines the home, from soaring two-story spaces and walls of windows capturing pastoral vistas to a sculptural floating spiral staircase connecting three expansive levels. The main floor was designed for grand-scale living and entertaining, with dual kitchens for daily use and catered events, expansive gathering areas, and a stately library suited for quiet work or private meetings. Upstairs, the spectacular two-story primary suite serves as a private sanctuary, featuring separate spa-inspired bathrooms and extraordinary dressing areas—including a dramatic two-story closet with a dedicated designer shoe showroom that might make even Imelda Marcos take notice—while eight generously sized bedrooms provide luxurious accommodations for family and guests. The lower level was conceived as a destination for recreation and entertainment, complete with a private bowling alley, 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 forward-thinking sustainable living. Despite its tranquil setting, the property offers convenient access to the Baltimore–Washington corridor via Interstate 70 and Interstate 95, placing major employers such as Johns Hopkins University and the National Security Agency within reach, while upscale shopping, dining, and entertainment await in nearby Columbia. Outdoor enthusiasts will also appreciate proximity to scenic escapes like Patapsco Valley State Park, completing a setting that blends privacy, accessibility, and natural beauty. With permits, approvals, and architectural plans already in place—saving an estimated five years of development time—The Devlin Estate offers discerning buyers a singular opportunity to complete one of Maryland’s most extraordinary residences and shape a true generational landmark. Howard County’s updated allowance for Accessory Dwelling Units (ADUs) enhances the flexibility of this estate, offering possibilities for private guest residences, extended family living, or staff quarters.
