What Does a DIY Shed Kit Actually Include?
Before talking numbers, it helps to understand what you are paying for when you buy a DIY shed kit. This is where many first-time builders get surprised. The kit gets you most of the structure, but you still need to budget for everything that makes it usable and weather-ready.
Most Best Barns shed kits include:
- Pre-cut framing lumber
- Wall panels or framing components
- Trusses or roof framing pieces
- Doors and basic hardware
- Assembly instructions
What they usually do not include:
- Floor system
- Shingles or roofing felt
- Paint or stain
- Foundation materials
- Nails, screws, or specialty fasteners
Average DIY Shed Kit Costs by Size
DIY shed kit costs vary mainly by size and roof style. For Best Barns kits, here is a realistic price range for the kit itself.
- Small sheds 8x8 to 8x10: $900 to $1,600
- Medium sheds 10x12 to 12x12: $1,500 to $2,800
- Large sheds 12x16 to 12x24: $2,500 to $4,500
These prices reflect the kit only. They do not include the foundation, flooring, roofing materials, or finishes.
A common mistake is assuming a $2,000 kit means a $2,000 shed. In reality, most DIY builders spend another 40 to 80 percent of the kit price on additional materials.
Foundation Costs: The Base That Makes or Breaks Your Budget
The foundation is not optional. It keeps your shed level, dry, and square. Your choice here has a major impact on total DIY Shed Kit Costs.
Gravel Pad Foundation
- Cost: $200 to $600
- Best for small to medium sheds
- Requires ground leveling and landscape fabric
This is one of the most common options for Best Barns kits. It is affordable and works well if your yard drains properly.
Concrete Block Foundation
- Cost: $300 to $800
- Good for uneven ground
- Easier for DIYers than a full slab
Concrete blocks are popular for builders who want flexibility without pouring concrete.
Concrete Slab
- Cost: $1,500 to $4,000 or more
- Often required for large sheds
- May need permits or inspections
Concrete slabs are durable but can easily become the most expensive part of the project.
Flooring Costs Most Kits Do Not Include
Most Best Barns kits require you to build your own floor. Skipping the floor is not recommended unless your shed sits on a slab. A solid floor protects tools, lawn equipment, and stored items from moisture.
Typical floor materials include:
- Pressure-treated joists
- Plywood or OSB decking
- Floor fasteners
Average cost:
- Small shed: $250 to $400
- Medium shed: $400 to $700
- Large shed: $700 to $1,200
Roofing Materials Add Up Quickly
The roof frame comes with the kit, but the protective layers do not.
You will need:
- Roofing felt or synthetic underlayment
- Asphalt shingles or metal roofing
- Drip edge and nails
Average roofing costs:
- Asphalt shingles: $150 to $400
- Metal roofing: $300 to $800
- Asphalt shingles are the most common choice because they are affordable and easy for first-time builders.
Paint, Stain, and Weather Protection
Bare wood will not last long outdoors. Finishing materials are required. Best Barns sheds are easy to customize here. Many homeowners match the shed color to their house or fence.
Budget for:
- Exterior paint or stain
- Primer if painting
- Brushes, rollers, or sprayers
Typical cost:
- $150 to $350 depending on shed size
Tools You May Need to Buy or Rent
If you already own tools, this part may cost nothing. If not, plan ahead.
Common tools for a DIY shed build:
- Circular saw
- Power drill
- Level
- Hammer or nail gun
- Ladder
- Tape measure and square
Estimated tool cost:
- Buying tools: $200 to $600
- Renting specialty tools: $50 to $150
