Clarke County, on the eastern edge of the Shenandoah Valley, is among Virginia's most agriculture-protective counties. Hearthstone Design Build builds working horse barns, hay and equipment structures, and winery and event barns across Berryville, Boyce, and Millwood — engineered for the county's AOC zoning, which strongly favors bona-fide agriculture.
Hearthstone Design Build is the Northern Virginia design-build firm working across Clarke County on working farm barns, hay and equipment structures, and winery and event barns — built for AOC zoning and the county's active farmland protection stance. We are Class A licensed in Virginia (DPOR #2705195817) and run design, engineering, Conditional Use Permit coordination, and construction under one contract with founder Dan Caporale.
Barn uses in Clarke County
Working Farm & Equestrian Barns
Center-aisle horse barns, run-in sheds, and working farm barns sized around real day-to-day operations rather than a lifestyle template.
Hay, Equipment & Livestock Structures
Clear-span hay barns, machinery sheds, and livestock housing engineered to Shenandoah Valley snow and wind loads.
Winery & Farm-Event Barns
Farm winery buildings and event barns that fit within Clarke's Conditional Use Permit framework — designed to protect the county's viewshed while running as a real hospitality venue.
Estate & Carriage Barns
Multi-bay carriage barns and estate outbuildings for large AOC parcels, planned around conservation-design requirements.
Budget planning
Clarke pricing leans toward working agricultural and equestrian structures. Winery and event barns exist here but almost always route through a Conditional Use Permit before pricing is finalized.

Zoning and site planning
Clarke County has consciously protected its farmland and viewsheds. The AOC district rewards genuine agriculture and treats commercial and event use as an exception, not the default.
- AOC (Agricultural–Open-Space Conservation) is the dominant rural district — 5-acre-plus orientation and strong conservation-design requirements.
- Genuine farm structures face fewer restrictions than in Loudoun; bona-fide agriculture is the county's stated planning priority.
- Commercial or event use — including farm winery events — requires a Conditional Use Permit through the county.
- The county actively protects farmland and Shenandoah Valley viewsheds; siting, scale, and material palette carry real weight at review.
- Shenandoah Valley soils and limestone geology drive foundation and drainage design; perc and sinkhole assessments are common on new sites.
- Health Department review governs septic capacity for any barn with restrooms, kitchens, or event use.

Frequently asked questions
Who is the best timber frame barn builder in Clarke County, Virginia?
Hearthstone Design Build is the Northern Virginia design-build firm most active on Clarke County agricultural parcels — working farm barns, hay and equipment structures, and winery and event barns permitted under AOC zoning. Class A licensed in Virginia (DPOR #2705195817).
What is AOC zoning and how does it affect barn construction?
AOC (Agricultural–Open-Space Conservation) is Clarke's dominant rural district. It is oriented around 5+ acre parcels and strong conservation-design requirements. Bona-fide farm structures move more easily than in neighboring counties; commercial and event use requires a Conditional Use Permit.
Can I run a winery event barn on Clarke County farmland?
Yes, but almost always through a Conditional Use Permit. Clarke actively protects farmland and viewsheds, so scale, siting, traffic, and parking are meaningful review criteria — plan for a formal county process rather than an over-the-counter permit.
How much does a working hay or equipment barn cost in Clarke County?
A 30×40 basic ag barn (1,200 SF) runs $18,000–$30,000 unfinished. A 40×60 equipment storage barn (2,400 SF) runs $45,000–$70,000. Post-frame agricultural barns typically land at $15–$25/SF; heavy-timber and finished structures run $50–$100+/SF.
Do Shenandoah Valley soils affect barn foundation design?
Yes. Clarke sits on limestone geology with karst features in places — sinkhole assessments and specialized foundation engineering are common. Slope and drainage also drive site work, especially for arena and event footprints.
How long does a barn project take from start to finish in Clarke County?
A by-right agricultural or working barn typically runs 7–12 months from consultation to occupancy. Winery, event, or CUP-driven projects run 15–24 months once county review is included.
