How Much Does It Cost to Build a 14×20 Gambrel Shed?
Pricing assumptions
- Pricing basis:our engine's baseline materials price table, built from Charlotte, NC–area retail estimates (spot-checked against Home Depot listings) — the region we operate in, not a location-specific quote for your ZIP code. Lumber and materials prices vary by region and week; treat the total as a planning baseline and check your local supplier.
- Price effective date: 2026-08-18. This date moves whenever the underlying price table is updated.
- Waste factors: included — a 10% waste allowance on framing lumber and sheet goods (higher on hip roofs and around openings), matching what the engine assumes for every quote it generates.
- Excluded: sales tax, delivery/freight, tools, permits, and site work (grading, foundation excavation). Labor is shown separately below only when an estimate is available — it is never folded into the materials number above.
Materials Cost Breakdown
| Category | Estimated Cost | % of Materials Total |
|---|---|---|
| Framing Lumber | $1,801 | 20% |
| Sheathing | $1,389 | 16% |
| Roofing (Shingle) | $1,058 | 12% |

| Hardware & Connectors | $144 | 2% |
| Materials Total | $8,929 | 100% |
DIY vs. Hiring the Framing Out
- DIY (materials only): $8,929 — you supply the labor.
- If you hire out the framing: add an estimated $5,960 in crew labor (roughly 10 build days for a 2-person crew), for a materials-plus-labor total of $14,889. This is crew labor only — it excludes contractor markup, permits, and site work, so a real contractor quote will run higher.
Frequently Asked Questions
- How much does it cost to build a 14×20 gambrel shed?
- Based on our engine's default materials bill of materials for the 14×20 Barn with Loft plan, the computed materials cost is $8,929. Materials run approximately $8,900–$11,400 including the loft package. Per square foot of USABLE surface — floor plus loft — it undercuts every non-gambrel plan its size, which is the barn's entire economic argument.
- What's included in this materials estimate?
- The estimate covers every material line in the plan's bill of materials — framing lumber, sheathing, roofing, siding, doors & windows, fasteners, and hardware — priced at the engine's default rates. It excludes taxes, delivery, tools, and (unless shown below) labor. See the assumptions block on this page for the full list.
- Does this include labor to build it?
- No — the number above is materials only. If you hire out the framing, our engine also computes a separate crew-labor estimate of $5,960 (about 10 build days for a 2-person crew), for a materials-plus-labor total of $14,889. That figure excludes contractor markup, permits, and site work — it is not a contractor quote.
- What's the biggest cost driver for a 14×20 shed?
- Framing Lumber is the largest line item at $1,801, roughly 20% of the total materials cost. The full category breakdown is on this page.
