From First Conversation to Move-In Day
Step 1
Consultation (Week 1)
We learn your budget range and how you want to live. You leave with a clear picture of what your project involves and what it costs — not a vague promise to follow up with a quote.
Step 2
Design (Weeks 2–4)
Custom floor plan developed to your spec. 3D renderings before anything moves forward. Revisions happen here, not on the job site.
Step 3
Permitting (Weeks 4–6)
We deliver permit-ready plans. Your contractor handles submission and approval with your local building department.
Step 4
Site Prep & Foundation (Weeks 6–9)
Your contractor prepares the site, installs the foundation, and runs utilities.
Step 5
Shell Construction (Weeks 10–14)
Frame, siding, roofing, windows, and doors. The exterior goes up fast — typically two to four weeks once the foundation is ready.
Step 6
Interior Finish (Weeks 14–36+)
HVAC, plumbing, electrical, insulation, drywall, flooring, cabinetry, fixtures. Timeline varies by scope and finish level.
Typical total timeline: 6–10 months from consultation to move-in.

Turnkey Maryland Barndominium Builders & Prices
Maryland’s cost reflects a mixed-region build — Chesapeake and Eastern Shore sites take coastal wind and flood exposure, while the western panhandle carries snow load and deeper frost. Turnkey builds here run about $170–$230 per square foot of heated, finished living space. Mid-Atlantic labor and materials sit above the national median. The bigger lever on your total is how much you condition: unconditioned shop space runs roughly $65–$95/sq ft and covered porch $50–$70.
On a 60×60 (3,600 sq ft), that split is the whole spread — a shop-forward build lands around $375K–$520K, a home-forward one $525K–$715K, same footprint and same county. A steel shell kit alone starts around $28/sq ft. What yours costs comes down to footprint, living-to-shop ratio, and finish level .
