5940 Barberry Trl, Lorton, VA 22079

Shovel-Ready Building Lot in Fairfax County - Fully Approved Septic & Well Permits Already Secured Selling at Virtual Auction | Gunston Manor Subdivision | Barberry Trail, Lorton, Virginia 22079 Rarely does a raw lot in Fairfax County come to market with its single biggest construction obstacle already solved. This +/-16,158 SF (+/-0.371-acre) parcel in the established Gunston Manor subdivision - Section B, Block 37, Lots 10-15 - has cleared the onsite sewage and water approval process that typically costs buyers months of delay and tens of thousands of dollars before a single shovel hits the ground. Why This Lot Stands Apart: Fully Engineered, County-Approved Septic System - Complete Alternative Onsite Sewage Environmental (AOSE/PE) design by Soils Inc., stamped by licensed Professional Engineer Wayne A. Savage, and sized to support a full 5-bedroom home. MicroFAST 0.75 Aerobic Treatment System - UV disinfection with a pressure-dosed low-pressure distribution (LPD) drainfield - a modern, high-performance system, not a basic conventional layout. 100% Reserve Drainfield Included - Full backup drainfield area engineered and reserved, protecting the buyer's investment for the life of the system. Approved Class IIIB Private Well Permit - Water supply already permitted and ready to drill. Fairfax County Health Department Certification Letter - Official confirmation that the site and design meet all current county regulations. Construction-Ready Package - Stamped drawings, drainfield and pump calculations, full soil profiles, and a recent topographic survey by Apex Surveys, LLP documenting boundaries, tree cover, and existing site conditions all convey to the successful bidder. Location: Tucked off Barberry Trail near Gunston Road, this lot sits in one of Fairfax County's more secluded, wooded corners of Lorton - minutes from the Potomac River, Gunston Hall Plantation, Pohick Bay Regional Park, and Mason Neck State Park. Zoned RE (Residential Estate, 1 DU/2AC), the setting offers space and privacy while remaining within easy reach of Fairfax County Parkway, Route 1, and the Fort Belvoir / Lorton commuter corridor into Washington, D.C. and Alexandria. The Opportunity: For a builder or owner-occupant ready to design and build, this lot removes the largest source of uncertainty, delay, and cost in Fairfax County residential development. The engineering is done, the permits are approved, and the documentation is in hand - buyers bring their house plans and go.
