Our detailed analysis will help you plan your budget better, whether you choose DIY assembly to save money or hire professionals to do the job.

Quonset hut prices by size and installation

The difference between kit-only prices and fully installed structures plays a crucial role in accurate budgeting while looking at Quonset hut costs. Several factors affect the pricing structure, such as steel gage, customizations, and size.

Kit-only cost per square foot

A Quonset hut’s simple shell costs the least. Kit prices start at $6.00 per square foot and can go up to $20.00 per square foot. Many manufacturers list prices starting at $9.00 per square foot for simple models. Companies like SteelMaster have starter kits that begin at $6,000 for a 20×20 structure.

Larger buildings cost less per square foot. To name just one example, a small 16×20 Quonset shed costs about $25.00 per square foot, while a large 10,000 sq. ft. warehouse might only cost $10.00 per square foot.

Installed cost per square foot

A complete installed Quonset hut costs between $20.00 and $50.00 per square foot. The total price has these components:

• Building kit (shell): $14.00-$28.00 per square foot
• Foundation installation: $4.00-$8.00 per square foot
• Construction labor: $3.00-$6.00 per square foot
• Interior finishing: $10.00-$100.00+ per square foot (varies greatly based on purpose)

The lot’s condition and building size affect site preparation costs:

• Small buildings (<1,500 sq ft): $0.50-$1.50 per square foot
• Medium buildings (1,500-3,000 sq ft): $1.00-$3.00 per square foot
• Large buildings (>3,000 sq ft): $1.50-$4.00 per square foot

Price ranges for common sizes (e.g., 20×20, 30×40, 40×60)

Popular sizes come with these typical price ranges:

20×20 (400 sq ft):

• Kit only: $2,400-$8,000
• With installation: $8,000-$20,000
• SteelMaster starting price: As low as $6,000

30×40 (1,200 sq ft):

• With installation: $48,000-$120,000
• Arch Buildings model: $24,010 (on sale from $26,676)

People with tight budgets can save about 30% on foundation costs by using a perimeter foundation instead of a full concrete slab.

Cost breakdown by usage type

Your Quonset hut’s purpose affects its cost structure. Each application needs different levels of finishing, features, and interior work that can change your budget needs.

Garage or storage use

A simple garage or storage Quonset hut costs less than other types. These structures cost $20.00 to $30.00 per square foot after installation. Common sizes are 20×20 (400 sq ft) and 30×30 (900 sq ft), and we designed them for vehicle storage. These buildings have roll-up or sliding doors that make access easy, with minimal interior finishing.

Workshop or commercial use

Workshop applications need extra features that push costs higher. Most workshop Quonset huts cost $30.00 to $50.00 per square foot installed. Popular sizes are 30×40 (1,200 sq ft) and 40×60 (2,400 sq ft). The price goes up because you need electrical wiring, better insulation, and dedicated workbench spaces. One manufacturer says workshop Quonset hut kits alone cost $6.00 to $12.00 per square foot, and finishing costs make up the rest.

Agricultural or barn use

Farmers love Quonset huts because of their open interior spaces. These buildings cost $20.00 to $30.00 per square foot installed. They are affordable for sizes like 40×60 (2,400 sq ft) and 60×100 (6,000 sq ft). Quonset barns save you money compared to traditional structures. The kit costs about $11.00 per square foot, while traditional wood barns cost $25.00-$29.00+. The design works great for farming equipment, livestock, and crop storage.

Residential or guest house use

Residential applications cost the most, from $30.00 to $80.00 per square foot after installation. Small guest houses (20×30 or 30×40) cost more because they need extensive interior work. A simple Quonset home structure might cost $1,500 to $15,000, but full-time homes can reach $30,000 to $400,000+ after adding insulation, plumbing, electrical systems, and interior walls.

Key factors that affect Quonset hut cost

The final price tag of any Quonset hut project depends on several key factors. A realistic budget needs more than just the simple kit cost, so let’s look at what it all means.

Size and dimensions

The building size drives the cost per square foot. You’ll pay more per square foot for smaller structures (under 1,500 sq ft) compared to larger ones. A small 16×20 Quonset costs about $25/sq ft, while a 10,000 sq ft warehouse drops to around $10/sq ft.

Steel quality and thickness

Your local climate determines the required steel thickness. Heavy snow or high winds mean you need thicker gage steel to meet building codes. The higher price point buys you the structural integrity you need.

Location and delivery fees

The shipping adds 2-4% to your total building cost. Most Quonset kits pack neatly on 1-2 pallets, which keeps freight costs down. Remote locations cost more to ship to.

Labor and installation complexity

Professional teams charge about $3-6/sq ft. The good news is that 75% of buyers with buildings under 3,000 sq ft put them up themselves. This DIY approach saves 30-60% on the total project cost.

Interior and exterior finishing

Foundation installation runs $4-8/sq ft. The interior work prices vary: framing and drywall ($8-18/sq ft), electrical rough-ins ($2-6/sq ft), and plumbing rough-ins ($2-6/sq ft).

Customizations and accessories

Doors and windows make a big difference in final costs. Set aside $1,000-2,000 for overhead garage doors and about $500 for personnel doors. Customized end walls might cost anywhere from $2,000-8,000 based on your setup.

This amount covers foundation work, simple doors, and minimal finishing. Labor costs for building erection add $6.00-$20.00 per square foot, which means $7,200-$24,000 for labor costs.

Example 2: 40×60 barn with insulation

Agricultural storage needs make a 40×60 Quonset barn a significant investment. Steel kit costs typically range from $48,000-$84,000. The concrete foundation work costs an extra $28,800-$72,000. Door packages cost owners $8,000-$18,000, while insulation adds $3.00-$9.00 per square foot ($7,200-$21,600 total).

Example 3: 24×30 workshop with minimal finishing

The starting price for a 24×30 workshop kit ranges from $10,000-$11,000. Manufacturers offer this size at $10,000 with customizable endwalls. The final costs usually reach $15,000-$25,000 depending on interior finishes.

Example 4: 20×20 DIY guest house project

Small DIY projects like a 20×20 Quonset hut kit start at $6,000. This popular size serves as an entry-level option from most manufacturers. Complete installation costs range from $8,000-$20,000 with minimal finishing.

Conclusion

Quonset huts give you better value than traditional structures, and many factors affect their final cost. The prices vary based on size, usage type, and finishing levels. A simple kit price is just the start – installed costs usually run $20-$50 per square foot based on what you need.

The size of these arch-shaped buildings makes a big difference in your budget. Larger structures cost less per square foot, which makes Quonset huts an economical choice for warehouses and farms. Your intended use also affects the bottom line a lot. Storage buildings might cost $20-$30 per square foot installed, while home conversions can go up to $80 per square foot after finishing work.

Steel quality, delivery location, labor choices, and customizations are vital parts of your final investment. You can save 30-60% on total project costs by choosing DIY installation over professionals, especially with smaller buildings under 3,000 square feet.
