How Much Does It Cost to Build a Shed? Complete 2025 DIY Cost Guide

Building your own shed is one of the most rewarding DIY projects you can take on. Not only does it add value to your property, but it also gives you extra storage or workspace tailored exactly to your needs. But before you grab your hammer and saw, one big question stands in the way: How much does it cost to build a shed?

The answer depends on shed size, design, materials, and whether you build it yourself or hire someone. In this guide, we’ll break down the costs of building a shed so you can plan your budget with confidence.

Average Cost to Build a Shed

For most DIYers, the cost of building a shed falls in this range:

Small shed (6×8 – 8×10): $500 – $1,200
Medium shed (10×12 – 12×14): $1,200 – $2,500
Large shed (12×16 – 16×20): $2,500 – $5,000+

👉 On average, homeowners spend around $25–$50 per square foot when building a shed themselves. Hiring a contractor usually doubles that price.

Main Factors That Affect Shed Cost

1. Shed Size

It’s no surprise: bigger sheds cost more. A small 8×10 gable shed may only require a few hundred dollars in lumber, while a 12×16 barn-style shed could run several thousand.

Tip: Always go slightly bigger than you think you’ll need — running out of space is the #1 shed regret.

2. Materials

Your choice of materials makes a huge difference in cost.

Framing Lumber: The bulk of your expense. Pressure-treated wood costs more but lasts longer.
Roofing: Asphalt shingles are budget-friendly, while metal roofing costs more but can last 40+ years.
Siding: Plywood and T1-11 are affordable, while vinyl or cedar siding raise costs but improve appearance and durability.
Flooring/Foundation: Gravel pads are cheap; concrete slabs are durable but expensive.

Pro Tip: Always budget 10–15% extra for material waste and unexpected needs.

3. DIY vs. Hiring a Builder

Doing the work yourself saves thousands. For example, a 10×12 shed:

DIY Build: $1,200 – $2,000
Contractor Build: $3,000 – $5,000+

If you’re comfortable with basic carpentry, DIY is the best way to save money.

4. Design & Complexity

Simple shed plans (like a gable-style shed) are far cheaper to build than modern or barn-style designs with extra windows, lofts, or double doors.

5. Permits & Local Codes

Many cities require permits for sheds over a certain size (often 120 sq. ft.). Permit costs range from $50 to $250 depending on your location.

Example Shed Cost Breakdowns

Let’s break down what you might expect to spend on three common builds.

Small Gable Shed (8×10 ft) – Approx. $900

Lumber & framing: $400
Roofing (asphalt shingles): $120
Siding (T1-11 panels): $200
Doors, windows, hardware: $100
Foundation (gravel): $80

Best for: Basic storage (lawnmowers, garden tools, bicycles).

Medium Modern Shed (10×12 ft) – Approx. $1,800

Lumber & framing: $800
Roofing (metal): $250
Siding (vinyl): $400
Windows & door: $250
Foundation (concrete slab): $100

Best for: Workshops, hobby spaces, stylish backyard upgrades.

Large Barn-Style Shed (12×16 ft) – Approx. $3,200

Lumber & framing: $1,500
Roofing (metal or shingles): $500
Siding (T1-11 or lap siding): $800
Doors, loft materials, hardware: $300
Foundation (concrete slab): $100

Best for: Multi-purpose storage, hobby workshops, or sheds with lofts.

Cost-Saving Tips for Shed Builders

Choose simple shed plans. Fewer cuts, angles, and windows = lower cost.
Buy materials in bulk. Many stores offer discounts on lumber packs.
Use recycled or reclaimed materials. Old windows, doors, or leftover lumber can slash costs.
Do it yourself. Even hiring labor for part of the job doubles or triples costs.
Shop smart for tools. A shed tool bundle saves money compared to buying individually.

Hidden Costs to Keep in Mind

Paint/stain: $50–$200
Gutters/drainage: $100–$250
Locks & security hardware: $50–$150
Electricity/lighting (optional): $200–$800

Many first-time shed builders forget these extras, but they can add up quickly.

Shed Costs: DIY vs. Prefab Kits

You may wonder if it’s cheaper to buy a prefab shed kit instead of building from scratch.

Prefab Kit (8×10): $1,200 – $1,800
DIY Shed (8×10): $700 – $1,200

While prefab kits save time, they often use thinner, lower-quality materials. Building from plans usually gives you a sturdier, longer-lasting shed for less money.

Conclusion: Plan Your Shed Budget with Confidence

The cost of building a shed depends on size, design, and material choices. On average, expect to spend between $500 and $5,000 depending on your goals. The good news? With a solid DIY shed plan, you can keep costs under control, avoid mistakes, and end up with a shed that’s built to last.
