We design and build timber frame estate homes, carriage barns, and event structures across The Plains, Marshall, Upperville, Warrenton, and the surrounding RA and RC districts.
Every project runs under one contract with one accountable team — design, engineering, permitting, and field execution sequenced in parallel to compress the schedule and lock cost before drawings are finalized.
Fauquier County Zoning & Permitting
Fauquier's RA (Rural Agricultural) and RC (Rural Conservation) districts dominate the rural market — minimum lot sizes 10–25 acres, well and septic, VDOT entrance permits, and engineered stormwater management for any disturbance over 10,000 SF.
Feasibility reviews for Fauquier County parcels cover buildable envelope (setbacks, easements, slopes, floodplain), soil suitability for septic, well placement, VDOT entrance permitting, and stormwater obligations. We sequence these in parallel with schematic design so the permit clock starts as early as possible.
