14x30 Shed Material List

Quick Answer

A 14x30 gable shed with 8 ft walls, 16 inch on center framing, 4/12 roof pitch, pressure treated floor framing, OSB or plywood sheathing, a basic double door, and gravel foundation is a very large structure often used as a full workshop, multi-vehicle storage building, garage overflow, or serious hobby space. At 420 square feet, this size approaches the footprint of a small detached garage. The 14 ft width requires strong structural members, while the 30 ft length dramatically increases material quantities and makes layout accuracy critical.

You will need:

• Heavy pressure treated lumber for the floor system
• 2x4 wall framing

• Extensive floor, wall, and roof sheathing
• Panel or lap siding
• Asphalt shingles and underlayment
• Reinforced double door framing
• Large quantities of fasteners and hardware

Realistic 2026 total material cost: $9,200 to $14,200

This assumes a gravel base and basic exterior finishes only.

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 14 ft span requires substantial joists, and the 30 ft length demands many framing members.

Gravel Base

• 10 to 14 cubic yards of compacted 3/4 inch crushed gravel

Floor Frame (Pressure Treated)

Perimeter

• 2x12x30 PT – 2 (long rim joists)
• 2x12x14 PT – 2 (end band joists)

If 30 ft boards are unavailable, splice sections over blocking.

Floor Joists (16 inch OC across 14 ft span)

• 2x12x14 PT – 22 to 23

Heavy joists are necessary to control deflection.

Floor Sheathing

• 3/4 inch tongue and groove plywood or OSB – 14 sheets

Fasteners

• Exterior-rated screws or galvanized framing nails
• Heavy-duty joist hangers strongly recommended

Wall Framing

Framed 16 inch on center.

• 2x4x8 studs
• 185 to 205 total
• Includes perimeter walls
• Additional studs for corners and door framing
• Waste allowance

Plates

• 2x4x30 – 6 (long walls, double top plates + bottom plates)
• 2x4x14 – 6 (end walls)

Splicing shorter boards is common for very long walls.

Double Door Framing

Typical opening: 60 to 72 inches wide.

• 2x12x8 – 2 (header material)
• 1/2 inch plywood spacer
• Jack and king studs included in stud count

Roof Framing

A 14 ft span typically requires 2x8 rafters.

Rafters (4/12 pitch, 16 inch OC)

• 2x8x18 – 44 to 46
• Approximately 22 to 23 rafter pairs

Ridge Board

• 2x12x30 – 1

Collar Ties or Ceiling Joists

• 2x4x14 – 22 to 23

Sheathing

Large surface areas require substantial panel quantities.

Wall Sheathing

• 7/16 inch OSB or plywood – 36 to 38 sheets
• Panel siding may eliminate separate sheathing

Roof Sheathing

• 7/16 inch OSB or plywood – 22 to 24 sheets

Siding

Panel siding is common for large sheds.

T1-11 or LP SmartSide Panels

• 36 to 38 sheets

Alternative siding systems require additional trim and backing materials.

Roofing

Underlayment

• 3 rolls synthetic underlayment

Drip Edge

• 14 to 16 pieces (10 ft lengths)

Shingles

• Approximately 5 squares
• 16 to 18 bundles depending on waste

Roofing Nails

• 14 to 17 lb box

Hardware and Fasteners

• 16d framing nails or structural screws
• 8d nails for sheathing
• Exterior construction screws
• Construction adhesive (8 to 10 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: $550 to $1,100
• Pressure Treated Floor Framing: $2,400 to $3,800
• Wall Framing Lumber: $1,600 to $2,600
• Roof Framing Lumber: $1,600 to $2,600
• Sheathing (walls and roof): $2,800 to $4,300
• Siding (T1-11): $1,900 to $3,000
• Siding (LP SmartSide): $3,200 to $5,100
• Siding (Vinyl system): $4,200 to $6,700
• Roofing: $1,100 to $1,800
• Hardware and Fasteners: $500 to $900

Total Estimated Range

With basic panel siding: $9,200 to $11,700

With upgraded siding: $11,700 to $14,200

Costs increase due to:

• Large floor area (420 sq ft)
• Heavy joists required for wide span
• Very long wall runs increasing stud count
• Extensive sheathing quantities
• Large roof surface area
• Reinforced door framing
• High fastener usage
• Potential delivery costs for long lumber

Tools Required

Standard framing tools plus equipment capable of handling very 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
• Multiple ladders
• Shovel and rake
• Plate compactor or heavy hand tamper

Helpful tools:

• Framing nailer
• Roofing nailer
• Laser level
• Sawhorses
• Clamps

Multiple helpers are strongly recommended.

Step-by-Step Build Overview

High-level sequence only.

• Prepare and compact gravel base across entire footprint.
• Build pressure treated floor frame and verify square.
• Install floor sheathing.
• Frame walls on the ground including double door opening.
• Raise walls with significant assistance, plumb, and brace securely.
• Install double top plates tying 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.
• Frequent checks for square and level are essential at this scale.

Common Mistakes

• Using undersized framing for wide spans. Leads to floor bounce or structural sag.
• Poor base preparation. Causes uneven settling across the building.
• Attempting to build without sufficient help. Components are heavy and difficult to maneuver.
• Losing square over long distances. Causes roof and siding alignment issues.
• Underestimating material quantities. Leads to delays and increased costs.
• Weak door framing. Leads to sagging or binding doors over time.

Is It Worth Building Yourself?

DIY material cost: $9,200 to $14,200

Typical prebuilt 14x30 shed delivered in 2026: $18,000 to $32,000

DIY savings typically range from $8,800 to $17,800.

Consider:

• Build time of roughly 8 to 14 days with assistance
• Handling very heavy materials
• Need for precise layout
• Possible permits and zoning requirements

For homeowners comfortable with construction tasks, building yourself can provide substantial savings.

It does not include:

• Exact rafter angle calculations
• Detailed wall framing layouts
• Structural engineering considerations
• Precise overhang measurements
• Optimized cut lists
