Building a shed costs $1,000 to $15,000 for a typical 10×10, with national averages of $4,000 to $5,653.123 A prefab kit shed of the same size runs $1,000 to $3,000 installed (HomeGuide).2 Prices below are national averages* for 2026.
*National averages, not local quotes. Your price depends on size, material, foundation, site prep, and whether it’s a kit or a custom build.

slab per sq ft, HomeGuide
Quick math: a 120-sq-ft shed at Angi’s $15 to $150 per square foot = $1,800 to $18,000, matching its size table exactly, our arithmetic.1 Fixr’s higher $5,653 average reflects its reference build — a pine-sided 10×12 with a gable roof — while Angi’s $4,000 mixes in cheap kits, our reading.13
Cost by size (HomeGuide)
| Size | Prefab installed | Custom built |
|---|---|---|
| 8×8 (64 SF) | $650 – $1,900 | $1,600 – $9,600 |
| 10×10 (100 SF) | $1,000 – $3,000 | $2,500 – $15,000 |
| 10×12 (120 SF) | $1,200 – $3,600 | $3,000 – $18,000 |
| 12×12 (144 SF) | $1,450 – $4,300 | $3,600 – $21,600 |
| 12×20 (240 SF) | $2,400 – $7,200 | $6,000 – $36,000 |
| 20×20 (400 SF) | $4,000 – $12,000 | $10,000 – $60,000 |
Prefab runs $10 to $30 per square foot installed; custom builds run $25 to $150 (HomeGuide).2 Fixr’s planning number for a professionally built unfinished shed is ~$50 per square foot, rising toward $200 with insulation and electricity for an office or workshop finish.3
Cost by material
| Material | Angi | Fixr (typical build) |
|---|---|---|
| Resin / vinyl | $200 – $5,000 | ~$1,000 (kit) |
| Metal | $500 – $7,000 | ~$4,500 (wood-framed) |
| Wood | $3,000 – $15,000 | ~$6,000 |
| Concrete | — | ~$18,000 |
| Brick | $3,200 – $30,000 | ~$24,000 |
Resin kits are the budget entry; brick is the premium outlier because the material and slow assembly stack labor costs (Angi).1 Fixr cautions that cheap metal kits hold up poorly in high wind or snow, its review.3

Worked examples
Example 1 — 8×8 resin kit, DIY. $650 to $1,900 installed equivalent (HomeGuide); Angi’s vinyl band starts at $200 for the smallest units.12
Example 2 — 10×12 wood shed, pro-built, unfinished. 120 sq ft x ~$50 = ~$6,000 (Fixr’s rate), matching Fixr’s $5,653 average build, our arithmetic.3
Example 3 — 12×20 custom workshop, slab, wired. $6,000 to $36,000 build (HomeGuide) + 240 sq ft x $5 to $10 slab ($1,200 to $2,400) + $600 to $2,200 electrical, our arithmetic.21
FAQ
Cheapest way to get a shed? A small resin kit: $200 to $1,000 for the unit (Angi, Fixr), assembled in a day, our judgment.13
Do I need a foundation? Most sheds yes — gravel pad at $1.25 to $1.80 per square foot (Angi) or a slab at $5 to $10 (HomeGuide); pole-style sheds are the exception.12
Do I need a permit? Often for larger sheds: $50 to $145 where required (HomeGuide) — check local rules before pouring anything, our judgment.2
Kit or custom? Kits win on price ($10 to $30 per sq ft vs $25 to $150, HomeGuide); custom wins on size, layout, and finished interiors.2
What does a finished office shed cost? Up to $200 per square foot with insulation and power (Fixr) — at that point compare against our garage conversion cost guide, our judgment.3
