Full Material List
Quantities assume 8 ft wall height, 16 inch on center spacing, and a standard double door on one gable end.
Floor Framing
A 12x24 footprint requires strong framing to prevent deflection across the span.
Gravel Base
- 7 to 9 cubic yards of compacted 3/4 inch crushed gravel
Floor Frame (Pressure Treated)
Perimeter
- 2x8x24 PT – 2 (long rim joists)
- 2x8x12 PT – 2 (end band joists)
If 24 ft lumber is unavailable, splice shorter sections over blocking.
Floor Joists (16 inch OC across 12 ft span)
- 2x8x12 PT – 18 to 20
Floor Sheathing
- 3/4 inch tongue and groove plywood or OSB – 9 sheets
Fasteners
- Exterior-rated screws or galvanized nails
- Joist hangers recommended
Wall Framing
Framed 16 inch on center.
- 2x4x8 studs
- 140 to 155 total
- Includes perimeter walls
- Additional studs for corners and door framing
- Waste allowance
Plates
- 2x4x24 – 6 (long walls, double top plates + bottom plates)
- 2x4x12 – 6 (end walls)
Splicing shorter boards over studs is common if long boards are unavailable.
Double Door Framing
Typical opening: 60 to 72 inches wide.
- 2x8x8 – 2 (header material)
- 1/2 inch plywood spacer
- Additional jack and king studs included in stud count
Roof Framing
A 12 ft span requires at least 2x6 rafters.
Rafters (4/12 pitch, 16 inch OC)
- 2x6x14 or 2x6x16 – 36 to 40
Approximately 18 to 20 rafter pairs.
Ridge Board
- 2x10x24 – 1
Collar Ties or Ceiling Joists
- 2x4x12 – 18 to 20
Sheathing
Large structures consume substantial sheet goods.
Wall Sheathing
- 7/16 inch OSB or plywood – 26 to 30 sheets
Panel siding may eliminate the need for separate sheathing.
Roof Sheathing
- 7/16 inch OSB or plywood – 14 to 16 sheets
Siding
Panel siding is the most common choice for sheds of this size.
T1-11 or LP SmartSide Panels
- 26 to 30 sheets
Vinyl or lap siding systems require additional trim, backing, and accessories.
Roofing
Underlayment
- 2 to 3 rolls synthetic underlayment
Drip Edge
- 12 to 14 pieces (10 ft lengths)
Shingles
- Approximately 3 to 3.5 squares
- 10 to 14 bundles depending on waste
Roofing Nails
- 10 to 12 lb box
Hardware and Fasteners
- 16d framing nails or structural screws
- 8d nails for sheathing
- Exterior construction screws
- Construction adhesive (5 to 7 tubes)
- Hurricane ties strongly recommended
- Heavy-duty hinges (3 per door)
- Exterior double-door latch or lockset
- Padlock hardware
- Flashing for door header
Estimated Cost Breakdown
Typical 2026 pricing ranges.
- Gravel Base: $400 to $800
- Pressure Treated Floor Framing: $1,100 to $1,900
- Wall Framing Lumber: $1,100 to $1,900
- Roof Framing Lumber: $900 to $1,600

- Hardware and Fasteners: $300 to $600
Total Estimated Range
With basic panel siding: $6,500 to $8,500
With upgraded siding: $8,500 to $10,500
Costs increase significantly because of:
- Large floor area (288 sq ft)
- Long wall spans requiring many studs and plates
- Wider roof span needing stronger framing
- Extensive sheathing coverage
- Larger door opening reinforcement
- Increased fastener usage
- Higher transportation and handling costs
- Regional lumber pricing can significantly affect totals

Tools Required
Standard framing tools plus equipment suitable for handling large materials.
Essential tools:
- Circular saw
- Miter saw
- Drill and impact driver
- Framing hammer
- 4 ft or longer level
- Speed square
- Tape measure
- Chalk line
- Ladders
- Shovel and rake
- Plate compactor or heavy hand tamper
Helpful tools:
- Pneumatic framing nailer
- Roofing nailer
- Laser level
- Sawhorses
- Clamps
Assistance is typically required. Long walls and heavy components are difficult to handle alone.
Step-by-Step Build Overview
High-level sequence only.
- Prepare and compact gravel base across the entire footprint.
- Build pressure treated floor frame and ensure square.
- Install floor sheathing.
- Frame walls on the ground with double door opening.
- Raise walls with assistance, plumb, and brace securely.
- Install double top plates tying all walls together.
- Install ridge board and rafters.
- Add collar ties or ceiling joists.
- Install roof sheathing.
- Install drip edge and underlayment.
- Install shingles.
- Install wall sheathing if required.
- Install siding.
- Build and hang double doors.
- Install trim and hardware.
- Check level and square frequently throughout the build.
Common Mistakes
- Insufficient base preparation. Large structures amplify foundation problems.
- Using undersized floor framing. Causes long-term sagging and bounce.
- Underestimating materials. Running out mid-build can delay progress and increase costs.
- Attempting to build without help. Large wall sections are heavy and unsafe to lift alone.
- Weak door framing. Double doors require strong headers and support.
- Skipping structural connectors. Wind loads are significant on large sheds.
- Poor squaring practices. Small errors become major alignment issues.
- Inadequate roof framing. Wider spans demand proper lumber sizing.
Is It Worth Building Yourself?
DIY material cost: $6,500 to $10,500
Typical prebuilt 12x24 shed delivered in 2026: $11,000 to $20,000 depending on construction quality and finishes.
DIY savings can range from $4,000 to $10,000.
Consider:
- Construction time of 5 to 8 days with help
- Material delivery logistics
- Structural accuracy requirements
- Possible permits or zoning restrictions
For homeowners with construction experience and assistance, DIY is usually financially worthwhile. If speed, warranty, and convenience are priorities, a prebuilt structure may be preferable despite the higher cost.
