Custom Shed Cost

$3,500 to $28,000

A gable shed has two sloped roof planes meeting at a central ridge, with triangular gable ends on the front and back. This is the most common and least expensive shed style to frame: all rafters are identical cuts, and the gable end walls are simple triangles of framing and siding. A gable shed provides good headroom along the center ridge and is naturally ventilated through gable vents at each end. The main limitation is that all usable space is at floor level because the sloping ceiling eliminates headroom at the walls. A gable is the right choice for a garden tool shed, a lawn equipment shed, or a clean simple look.

$12,000 to $35,000

A gambrel shed has two slopes per side: a shallow upper slope and a steep lower slope, creating the classic barn silhouette. The main advantage is interior volume: a gambrel shed provides nearly full standing headroom from wall to wall and allows a usable loft above the knee wall. A 12x16 gambrel shed with a full loft effectively doubles usable storage compared to a gable shed of the same footprint. The trade-off is more complex rafter cutting (four cuts per rafter set versus two) and a knee wall that requires additional framing. Gambrel sheds add 25 to 40 percent in roof labor cost over a comparable gable. The classic barn look is popular for rural properties and is the standard style for larger workshop and storage sheds.

$2,800 to $7,500

A lean-to shed has a single sloped roof that pitches away from an existing structure (a house wall, garage, or privacy fence). The existing structure provides one full wall, reducing framing labor by 20 to 25 percent. A lean-to is the least expensive shed style per square foot because there is no ridge, no gable framing, and the single slope is the simplest possible roof to frame. The limitation is headroom: the rear wall is always lower than the front wall, restricting storage height at the back. A lean-to is ideal for a bike storage shed, a garden tool shed attached to a garage, or a firewood and equipment shelter along a fence line.

$7,000 to $22,000

A hip roof shed has four sloped planes with no vertical gable ends, giving the shed a compact, low-profile look that sits well in suburban settings where a tall gable might be prohibited by HOA rules or look out of place. The hip roof requires no gable siding, which reduces siding material slightly, but the hip rafter cuts at each corner are more complex than standard rafters, adding 25 to 40 percent more roof framing labor. Hip roof sheds also shed snow and wind load more evenly than gable sheds. The hip style is popular in HOA neighborhoods and as a standalone garden shed or potting shed where the look matters as much as the function.

$6,500 to $20,000

A saltbox shed has an asymmetrical gable roof: one slope is short and steep (the front), and the other slope is long and low (the back), creating the distinctive saltbox silhouette from colonial New England architecture. The long rear slope gives the shed more headroom at the rear than a standard gable while the front has a taller, more formal facade. The asymmetry requires different rafter lengths on each side and careful ridge placement, adding 15 to 25 percent to roof framing labor over a symmetric gable. A saltbox is a good choice for clients who want character and historical style in a garden shed or potting shed. The extended rear slope also provides good protection from wind-driven rain at the back wall.

Larger sheds cost more in absolute terms but less per square foot because the fixed costs of roofing, doors, and foundation are spread over more floor area. An 8x10 shed (80 sqft) typically costs $50 to $75 per square foot installed. A 16x24 shed (384 sqft) typically costs $45 to $65 per square foot at the same species and finish level. The roof is the largest fixed cost: framing, sheathing, roofing felt, and shingles cost nearly as much for a 10x12 shed as for a 12x16 shed because the labor to set up, cut rafters, and shingle is largely fixed regardless of roof area. Always calculate each shed from a full material take-off rather than scaling from a previous project.

Siding is typically 20 to 30 percent of a shed's total material cost, and species choice has a significant impact. Rough-sawn pine board-and-batten siding costs $1.50 to $2.50 per board foot and requires paint every 5 to 7 years to prevent rot. Cedar lap siding or board-and-batten costs $3.50 to $6.50 per board foot and can be left to weather naturally or stained every 5 to 7 years. Cedar also requires less installation labor because it is lighter and easier to cut and nail than pressure-treated or dense fir. Upgrading from rough pine to cedar siding adds $600 to $1,800 in material cost on a 12x16 shed. Board-and-batten siding is faster to install than lap siding (no need to rip boards or install starter strips) and gives a clean vertical look that is popular on garden sheds.

A simple gable roof (two sloped planes meeting at a ridge) is the fastest to frame and sheathe and is standard on most shed quotes. A gambrel roof (two slopes per side, barn-style) adds 25 to 40 percent more rafter-cutting labor because each rafter set requires four cuts at two different angles rather than two cuts. A gambrel also creates a usable loft space above the lower knee wall, which is the main reason clients choose it. A hip roof (four sloped planes, no gable ends) adds 30 to 50 percent more framing labor than a gable but requires less siding because the gable ends are replaced by roof planes. A lean-to (single-slope) roof attached to an existing structure is the simplest and least expensive roof style. A cupola adds $800 to $2,500 depending on size: it requires custom framing, flashing, and finishing but adds significant curb appeal and ventilation.

A single pre-hung 32-inch exterior door is the most affordable option at $180 to $350 at cost. A custom cedar double barn door (two 24x80 panels on strap hinges) adds $800 to $1,800 in labor and materials and is the right choice for a workshop shed that needs to move equipment in and out. Each window adds $130 to $300 at cost plus 2 to 3 hours of installation labor for opening framing, flashing, and casing. A garden shed typically has one window (east-facing for morning light). A workshop shed typically has three to four windows for natural light and cross-ventilation. Skylights add $400 to $800 each including installation and flashing. Custom divided-light windows (multiple panes, colonial style) add 30 to 60 percent over a standard single-pane window.

Pressure-treated skids on a gravel base are the most common and least expensive foundation for a storage shed: two to three 6x6 PT timbers, a 4-inch layer of compacted gravel under each, and simple shimming to level. Skid cost for a 10x12 shed is $150 to $350 in materials. Concrete piers (4-inch diameter, 12 to 18 inches deep) under a PT floor frame are sturdier and are preferred for larger sheds or sheds on sloped lots: add $400 to $900 for materials and a half-day of digging and pouring. A full concrete slab (4 inches thick, reinforced with rebar or wire mesh) is required for heavy-equipment sheds and is almost always required for sheds with electrical service: add $800 to $2,500 for a 10x12 to 12x16 slab, or subcontract it. Always quote foundation type separately so clients can see what they are paying for the structure versus the base.

A storage loft adds 15 to 30 percent to total project cost by requiring loft joists (typically 2x8 at 16 inches on center across the shed width), loft decking (3/4-inch plywood), a knee wall or railing at the loft edge, and a fixed ladder or ship-ladder. A gambrel shed with a full loft can double usable storage space at a fraction of the cost of expanding the shed footprint. Loft framing for a 16x24 shed takes 12 to 20 additional hours and adds $600 to $1,400 in materials (joists, decking, blocking, fasteners). An interior workshop with electrical outlets, LED shop lights, and an insulated ceiling adds $2,000 to $6,000 including materials and labor, but electrical work must be quoted and permitted separately from the carpentry scope.
