Prime Mountain Lot with Proven Buildability: This spectacular, nearly one-acre residential building lot at 1855 Ridge Rd, Haymarket, VA 20169, is a truly beautiful piece of land, offering a prime canvas for a custom home in the highly desirable Bull Run Mountain Estates community. The lot's value lies in its gorgeous setting: situated on the mountain's side, it provides serene Trees/Woods and the magnificent potential for coveted Mountain views yet it is still convenient to everything. This idyllic environment is easily accessible via paved roads. This beautiful 0.97-acre lot's appeal is significantly enhanced by its proven buildability, confirmed by the extensive site work, engineering, and successful permit applications previously executed by the seller. While those permits are now expired, all the detailed preliminary work, including soil testing and engineering for septic, grading, and architectural design, has been successfully completed and documented. This package provides a new buyer with a clear, high-confidence roadmap and a potentially accelerated path for submitting new plans and achieving their approvals. The available documentation shows that Prince William County previously approved plans for a spacious 2-story dwelling of 2,167 square feet, along with the corresponding Lot Grading Plan, demonstrating the style and scale of residence acceptable on the site. Furthermore, the Virginia Department of Health successfully certified the site for an onsite sewage disposal system designed to accommodate a 3-bedroom house. This approved septic design includes a robust 100% reserve area, indicating a fully compliant water and sewer solution is readily achievable. The future home will be served by a public water supply. Bull Run Mountain Estates is a picturesque community known for its tranquil setting, large lot sizes, and strong sense of community. Residents benefit from easy access to the Bull Run Mountains Natural Area Preserve, offering hiking trails and embracing the abundant wildlife, blending quiet, nature-focused living with access to excellent Prince William County schools, including Battlefield High School and Ronald Wilson Regan Middle/Junior School. The available documentation, including the expired permits and certification letters, may be useful in reducing a new buyer's upfront risk and non-construction timeline. Walk the property, stand on your future homesite, and capitalize on the magnificent potential and proven buildability of this exceptional lot.
