Leesburg Design-Build Contractor for Custom Homes and Outdoor Living
Hearthstone Design Build is a Leesburg, VA design-build contractor delivering custom homes, timber frame structures, luxury barns, and outdoor living programs across Loudoun County — under one contract, with one accountable team.
Based at 19 N King Street in downtown Leesburg, we know the H-1 historic district, the AR-1 and AR-2 rural overlays, and the Loudoun County permitting process intimately.
What a Design-Build Contractor Does in Leesburg
A design-build contractor delivers architecture, engineering, and construction under a single contract — eliminating the gap between the design team and the build team. In Leesburg, that single-contract model is especially valuable because the project has to clear Loudoun County zoning, Town of Leesburg historic review (in H-1), engineered stormwater, and utility coordination before a shovel touches the ground.
Hearthstone runs the full stack in-house: feasibility, schematic design, permitting, preconstruction budgeting, scheduling, and field execution. For Loudoun-specific zoning depth, see our Loudoun Zoning Intelligence hub. For the broader process, our 5-step build process explains how each phase hands off to the next.
Why Design-Build Fits Leesburg Owners
Leesburg estate projects have more moving parts than a typical suburban build. Historic review, dual jurisdiction near town limits, well and septic on rural parcels, and stormwater compliance all need to be sequenced correctly. Design-build solves the coordination problem at the root.

Preconstruction & Permitting in Loudoun County
Leesburg permits don't move at the same pace as Fairfax or Arlington. The historic district adds review layers, the rural overlays require additional environmental analysis, and stormwater compliance is enforced strictly under Chesapeake Bay Act jurisdiction. Knowing the rules upfront prevents six-figure design rework.

Leesburg Design-Build FAQs
What does a design-build contractor do in Leesburg, VA?
A design-build contractor delivers both architectural design and construction under a single contract. In Leesburg, that means we manage everything from initial site feasibility and Loudoun County zoning review through Board of Architectural Review submissions (in the H-1 historic district), engineering, permitting, construction, and final closeout — with one accountable team instead of separate architect and general contractor relationships.
How long does it take to build a custom home in Leesburg?
From signed contract through certificate of occupancy, expect 14–22 months for a typical Leesburg custom home. That breaks down to roughly 4–6 months of design and engineering, 2–5 months of permitting (longer in the H-1 historic district due to BAR review), and 9–14 months of construction. Rural parcels with well, septic, and long driveways add 1–2 months for sitework.
What does it cost to build a custom home in Leesburg, VA?
Custom homes in Leesburg generally start around $450 per square foot for builder-grade construction and run $650–$900+ per square foot for estate-grade design-build work with timber frame elements, custom millwork, and high-end finishes. A 5,000 SF estate typically lands in the $3M–$4.5M range. See our full cost breakdown in the custom home cost guide for Loudoun County.
Do you handle Board of Architectural Review submissions for Leesburg's historic district?
Yes. Properties in Leesburg's H-1 Historic District require BAR approval before building permits can be issued. We prepare the full submission package — site plan, elevations, materials palette, neighbor notification — and represent the project at BAR hearings. Properly prepared submissions clear in 4–6 weeks; incomplete applications restart the clock.
Can you build outside the Town of Leesburg in unincorporated Loudoun County?
Yes. We work across all of Loudoun County including AR-1 and AR-2 rural districts. For rural parcels, we coordinate the additional layers — well and septic permitting, VDOT entrance permits, and county-level stormwater review. Our Loudoun Zoning Intelligence hub covers the rural district rules in detail.
