10×10 Gable Shed Plans

About This Design

The 10×10 gable shed is a 100-square-foot building that hits an important regulatory threshold — many municipalities set their permit exemption at exactly 100 or 120 square feet, making this size the largest structure you can often build without a full plan review. The square footprint gives you equal wall lengths on all four sides, which simplifies framing and produces a clean, balanced appearance from any angle.

With 8-foot walls and a 6/12 roof pitch, the ridge sits at approximately 12 feet 6 inches — well under most HOA and zoning height limits for accessory structures. The compact 10-foot width means every rafter, header, and joist cuts from standard 10- or 12-foot lumber with minimal waste.

A centered 36-inch door on the front wall handles standard equipment, and windows on the rear and side walls provide natural light and cross-ventilation. The interior is spacious enough for a riding mower or a workbench — but not both at the same time. Choose your primary use case and organize accordingly.

Key Features

• 100 sq ft floor area — at or below permit-exempt threshold in many areas
• Square footprint simplifies framing and produces a balanced look
• 6/12 gable roof with ridge at ~12'6" — under most height limits
• 8' walls for comfortable headroom and wall-mounted storage
• 36" entry door plus two windows for light and ventilation
• All framing from standard 10' and 12' lumber lengths

Build Notes

A 10×10 sits on three 4×6 pressure-treated skids running 10 feet, spaced at 5 feet on center. Floor joists are 2×6 at 16-inch spacing spanning 5-foot bays. The square footprint means identical gable-end framing on both the front and rear walls, which lets you batch-cut cripple studs in matching pairs.

Frame walls with 2×4 studs at 16 inches on center. The 36-inch door header is a doubled 2×6, and window headers are doubled 2×4s. At 10 feet wide, use 2×6 rafters at 24-inch spacing for the 6/12 pitch — each rafter cuts from a 10-foot board with just enough length for the overhang.

This is an excellent first shed project. The compact size means you can stand the walls by hand, and the square plan forgives minor racking errors because diagonal bracing works equally well in both directions.

Best For

The 10×10 is the sweet spot for a dedicated lawn-and-garden shed. A riding mower parks in the center with room around it for a shelf unit on one side wall and a pegboard tool wall on the other. It also works as a compact workshop if you choose not to park equipment — an 8-foot workbench along the back wall leaves a 10-foot-deep working area. Homeowners who need to stay under a permit threshold without sacrificing usable space consistently choose this size.
