A DIY Cost Guide
Building your own shed can be an affordable way to add storage, create a backyard workshop, or make room for garden equipment. But how much does it actually cost to build a shed?
For a typical wood-framed shed, a DIY builder might spend approximately $1,500 to $5,000 on materials, depending on the shed's size, design, foundation, roofing, and finish. Larger sheds or more elaborate designs can cost considerably more. Hiring a contractor will generally increase the total because you're also paying for labor and installation.
The best way to estimate your shed-building budget is to start with the size you need, choose a suitable foundation, and calculate the materials required for the structure.
How Much Does It Cost to Build a Shed by Size?
The cost of building a shed varies considerably with its dimensions. A small garden storage shed requires less lumber, siding, roofing, and flooring than a large workshop.
The following figures are general DIY material budget estimates for wood-framed sheds. They're intended as planning guides rather than fixed prices or quotes.
Shed Size Approximate DIY Material Cost.
8x10 shed $1,500–$3,000
10x12 shed $2,000–$4,500
12x16 shed $3,200–$7,000
12x20 shed $3,800–$9,000
These estimates can change depending on your location, lumber prices, building specifications, and material choices. A basic storage shed with a gravel foundation will generally cost less than a fully finished workshop with a concrete slab, insulated walls, and electrical wiring.
Before committing to a design, work out how much storage or workspace you actually need. Choosing the right shed size from the beginning can help prevent unnecessary material costs.
What Materials Do You Need to Build a Shed?
A shed's total material cost is made up of several major components. Understanding these expenses helps you identify where your budget is going.
1. Foundation and Site Preparation
Your foundation is one of the first decisions you'll need to make.
Common shed foundation options include:
Gravel base with treated skids
Concrete blocks with treated skids
Concrete slab
A gravel foundation is often a practical, budget-friendly choice for a basic storage shed. Concrete slabs generally cost more but can provide a durable base for larger or heavier structures.
Site preparation can also add to your budget. You may need to level the ground, remove vegetation, improve drainage, or bring in additional gravel.
2. Floor Framing and Flooring
The shed floor typically consists of treated lumber for the supporting frame, floor joists, and plywood or another suitable decking material.
The size of the shed, joist spacing, and floor loading requirements will influence how much lumber and decking you need.
If you're planning to store heavy equipment or use the shed as a workshop, make sure the floor is designed to handle the expected weight.
3. Wall Framing and Siding
Wall framing usually includes studs, top and bottom plates, headers, and structural sheathing where required.
Your siding choice will also affect the final price. Common options include:
Plywood or engineered wood siding
Vinyl siding
Metal siding
Wood boards
Basic wood siding may be suitable for a simple garden shed, while more decorative or durable materials can increase the cost.
4. Roof Framing and Roofing
Roof materials are another significant part of the budget.
A typical wood-framed shed roof may require rafters, roof sheathing, underlayment, shingles or metal roofing, ridge components, and flashing.
A simple lean-to roof can require less framing than a more complex roof design. A gable roof provides additional headroom and is a popular choice for storage sheds and workshops.
5. Doors, Windows, Hardware, and Finishing
Don't forget the smaller items that can add up.
Your budget should include door framing, hinges, handles, nails, screws, brackets, trim, paint, stain, and weatherproofing materials.
Windows, double doors, and additional ventilation can also increase the total cost.
DIY Shed Building vs. Buying a Shed Kit
Building from plans, purchasing a kit, or hiring a contractor are three common approaches.
Building from shed plans: You purchase or use a set of plans and source the materials yourself. This gives you flexibility over material selection and design, while allowing you to do the construction work yourself.
Buying a shed kit: A kit generally provides pre-selected materials or components. It can simplify the building process, but the final cost depends on the kit, delivery, foundation, and assembly.
Hiring a contractor: A professionally built shed can save time and reduce the amount of construction work you need to do. However, labor and installation can significantly increase the overall price.
For someone comfortable with DIY construction, building from plans can be a good way to control the budget and customize the shed to suit the backyard.
How to Reduce the Cost of Building a Shed
If you're trying to keep your shed project affordable, a few practical decisions can make a difference.
Choose the right size. Avoid building more space than you need.
Keep the design simple. A straightforward rectangular shed is generally easier to construct than a complex design.
Compare material prices. Check local lumberyards and building suppliers before purchasing.
Use a practical foundation. Select a foundation suitable for your site, shed size, and local requirements.
Plan your material quantities. A detailed material list can help reduce waste and avoid unnecessary purchases.
Do the work yourself where practical. DIY labor can reduce the total project cost, although specialist work may still be needed.
Always check local building codes, permit requirements, setbacks, and foundation requirements before starting construction.
Estimate Your Shed Building Materials
One of the easiest ways to get a more realistic budget is to calculate the materials needed for your specific shed.
The Shed Nerd's Shed Material Estimator can help you plan the materials for your project. Enter your shed dimensions, framing spacing, foundation type, roof style, and other details to generate an estimated material list.
It's a useful starting point for working out what you'll need before visiting your local building supplier.
You can also explore outdoor shed plans to find a design that suits your storage needs, available space, and building experience.
Frequently Asked Questions
