Welcome to Valhalla, an extraordinary historic residence set in one of the most beautiful and private pastoral settings in Western Howard County. Originally built in the early1800s and thoughtfully expanded over the years, this remarkable 5-bedroom, 4-full and 2-half-bath home offers just under 5,000 square feet of living space, an oversized side-loading two-car garage, timeless character, and an exceptional connection to the surrounding countryside. Offered at $1,500,000, this listing includes the Valhalla residence at 1575 Marriottsville Road and its approximately one-acre parcel. What makes this offering even more exceptional, however, is a potential opportunity for the right buyer to expand beyond the subject property and assemble one of Howard County's most distinctive private estates. Surrounding Valhalla is an approximately 92-acre agriculturally preserved property, along with 2 additional residences, each situated on its own approximately one-acre parcel. These additional properties are not included in the $1,500,000 offering price but may potentially be available for purchase separately or collectively, creating the possibility of assembling an approximately 95-acre private equestrian estate, multi-generational family compound, or legacy property. Imagine the possibilities: 3 separate residences, approximately 92 acres of permanently preserved land, extensive open pasture, large barn with full live-in apartment and office space, run shed, two garage/workshops, historic storage building, established white fencing, equestrian facilities, trails, extraordinary privacy, pastoral views and direct adjacency/access to Patapsco Valley State Park. Horses are currently enjoyed on the surrounding property, and the setting offers an exceptional opportunity for the equestrian buyer seeking space, privacy and access to miles of surrounding natural beauty. The approximately 92 surrounding acres are currently protected through agricultural land preservation, helping preserve the open-space character and pastoral setting that make Valhalla so special. The MD Agricultural Land Preservation Foundation recognizes equestrian activities and facilities as agricultural uses, subject to applicable requirements. The relationship between the residences, preserved acreage and surrounding parkland creates an opportunity that would be extraordinarily difficult to reproduce. A buyer acquiring the additional properties could potentially enjoy approximately 95 acres with multiple residences, expansive pasture, equestrian infrastructure and remarkable privacy-all within the Baltimore-Washington corridor. The broader setting is equally compelling, with the property neighboring both Patapsco Valley State Park and the expansive Bon Secours property, further contributing to the area's protected, rural character. Valhalla itself is equally impressive. A substantial 1999 addition expanded the home to create an extended primary suite, enlarged kitchen, wine vault and flexible lower-level living/office space. The home has been recently updated as the featured property for Historic Ellicott City, Inc.'s 35th Decorator Show House, bringing together its historic architecture and character with beautifully refreshed interiors. From the inviting front porch overlooking pastoral views to the property's direct connection with the surrounding countryside and parkland, Valhalla offers a lifestyle rarely available in Howard County. Purchase Valhalla on its own and enjoy an extraordinary historic home on approximately one acre-or explore the potential opportunity to create something truly exceptional by acquiring additional surrounding properties. For the equestrian buyer, multi-generational family, conservation-minded purchaser or buyer searching for a private legacy estate, the possibility of assembling approximately 95 acres, three residences and an established equestrian setting in Western Howard County represents a remarkably rare opportunity.
