A 12×20 Amish shed typically costs $7,000-$16,000 for the structure, with an average near $11,000; delivery, site preparation, and a foundation can raise the installed total to $9,000-$21,000. Price depends mainly on siding and roof materials, door and window choices, local labor, access, and whether the shed is built on-site or delivered assembled.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 12×20 shed structure | $7,000 | $11,000 | $16,000 | Standard to upgraded materials and trim |
| Delivery and placement | $300 | $900 | $2,000 | Distance and site access affect the fee |
| Base or foundation | $700 | $1,800 | $4,000 | Gravel, blocks, or a concrete pad |
| Installed project total | $9,000 | $13,700 | $21,000 | Before unusual grading or permits |
What a 12×20 Amish-built shed usually includes
A 12×20 shed has 240 square feet of floor area. Basic packages commonly include a framed floor, wall framing, siding, a shingle or metal roof, one entry door, and standard trim. Prices vary because “Amish-built” describes a building tradition or seller’s product line, not one fixed specification or a single national price.
For a standard wood-sided model with ordinary access, budget about $7,000-$13,000 for the building itself. A painted or premium-siding model with upgraded doors, windows, roof details, or heavier floor framing can reach $16,000 or more. That is about $29-$67 per square foot for the structure, excluding site work and delivery.
Assumptions: 240-square-foot building, standard residential use, typical U.S. materials, and no major grading or utility work.
How siding, framing, and labor shape the quote
Ask for a line-item quote that separates the building package from delivery and site work. A low advertised price may cover a basic shell but exclude a floor, paint, ramp, or installation. The ranges below are typical planning estimates; some sellers bundle these items, so the figures should not be added twice when comparing quotes.
| Quote item | Typical range | Unit or scope | What changes the price |
|---|---|---|---|
| Framing and floor package | $1,600-$3,200 | 240 sq ft shed | Joist spacing, floor thickness, and load rating |
| Siding and exterior trim | $1,500-$4,000 | Wood or engineered siding | Grade, finish, and paint or stain |
| Roof materials | $700-$1,800 | Shingles or metal | Roof pitch, underlayment, and metal gauge |
| Assembly labor | $1,200-$3,000 | On-site or shop-built | Crew size, access, and construction method |
| Delivery and placement | $300-$2,000 | Per delivery | Route distance, turning space, and equipment |
| Base preparation | $700-$4,000 | Gravel to concrete | Excavation, drainage, and local material rates |
Labor and material specifications matter more than the “Amish” label when comparing two quotes. For a custom on-site build, labor may account for roughly $1,200-$3,000, with crew rates often around $50-$90 per worker-hour before travel or minimum charges.
Which dimensions and upgrades push the price higher?
Floor loading is a key decision if the shed will store a riding mower, workshop equipment, or heavy materials. A standard floor may be sufficient for household storage, while closer joist spacing or thicker decking can add roughly $300-$900. Confirm the stated floor load rather than assuming every 12×20 model is built for machinery.
Roof and exterior choices also move the quote. Metal roofing can add about $500-$1,500 over basic shingles, while premium siding or a factory finish may add $800-$2,500. Adding two or three windows, a wider double door, or a ramp can add another $300-$1,200, depending on size and hardware.
Moving from a 10×16 model to 12×20 adds 80 square feet, or 50% more floor area, but the total price does not rise in a perfectly straight line. A 12-foot-wide building may require different framing or delivery equipment than a narrower shed, particularly where access is restricted.
Can a truck or shed mover reach the backyard?
Delivery can be straightforward when the shed can be placed near the driveway, but a tight gate, steep slope, overhead wires, or soft ground may prevent direct placement. Ask the seller to confirm required gate width, turning clearance, and overhead height before paying a deposit. A delivery inspection or site visit may cost $50-$200, sometimes credited toward the order.
When an assembled shed cannot reach the site, on-site construction may be available for an added $500-$2,000, depending on travel, crew time, and access. Separate grading, tree removal, or drainage correction can add $300-$2,500 or more. Check whether the quote includes blocking or leveling; delivery alone may not include a finished base.
Site access can change the installation method and total more than a small material upgrade. Ask for written limits on delivery distance and placement, plus the charge for a failed delivery attempt.
How three 12×20 shed quotes can differ
A basic storage shed with wood siding, shingles, one door, and a gravel base might be quoted at $7,800 for the structure, $650 for delivery, and $1,000 for the base, totaling about $9,450. This example assumes a level, accessible suburban lot and no windows or custom finish.
A midrange model with a finished exterior, metal roof, two windows, and upgraded floor could cost $11,200 for the structure, $900 for delivery, and $1,700 for a compacted gravel base, or about $13,800 total. A premium workshop-style build with reinforced flooring, multiple openings, a painted finish, and a concrete pad could reach $15,500 for the shed, $1,400 for delivery, and $3,500 for site and foundation work, totaling $20,400.
These examples show why the building-only price and installed total should be compared separately. Local quotes can differ with regional wages, haul distance, and the seller’s standard package.
How local labor and delivery change the total
Prices tend to be lower where shed builders and dealers operate nearby, since shorter delivery routes and lower labor rates can reduce the quote. In rural areas near a builder, delivery may be $300-$800; a long-distance or difficult urban placement can run $1,000-$2,000 or more. Big-city labor and foundation work may cost 10%-25% above a comparable small-town project.
In northern markets, snow-load requirements or a steeper roof can raise material and framing costs. In areas with wet soil, drainage and a raised base may add $300-$1,500. Local rules also vary: permits may cost about $50-$500, and some jurisdictions require setbacks, anchoring, or inspections for a 240-square-foot outbuilding.
Get a local permit answer before ordering, because a 12×20 shed may exceed a jurisdiction’s size limit for permit-free structures. The seller’s estimate may not include permit fees or code-required upgrades.
Where to trim the 12×20 shed budget
Keep the footprint and layout simple, choose standard door and window sizes, and compare the seller’s base package before selecting upgrades. Shingles may be less expensive than metal roofing, and an unfinished interior avoids paying for lining or insulation that storage use may not require. Avoid reducing floor strength if heavy equipment will be stored inside.
Compare at least three written quotes using the same siding, roof, floor rating, delivery distance, and foundation scope. Ask whether delivery is bundled, whether the base is level and included, and what warranty applies to materials and workmanship. Scheduling outside the busiest spring and early-summer period may improve availability, though savings are not guaranteed.
The clearest savings usually come from avoiding unneeded options and preventing site or delivery surprises. If the existing ground is level and drains well, a properly prepared gravel base may cost substantially less than a concrete slab; choose concrete only when the intended use justifies it.
