30×30 Metal Building with Slab Cost

A 30×30 building has 900 square feet of space. A foundation for this size of building may cost between $3 to $12 per square foot, depending on whether you pour it yourself or hire a local contractor to prepare the foundation for you. Expect to pay at least $2,700 for a DIY foundation, and at least $7,200 to have a concrete slab poured for you.

If you plan to use your building as a barn, you may be able to anchor it directly to the ground or a gravel foundation.

Installation is free and usually takes about 1-2 days. 

Lifespan and Warranties

Steel buildings can last for well over 50 years with proper annual maintenance, making them a cost-effective long-term investment. Our 30×30 steel buildings come with a 1-year craftsmanship warranty and a 20-year warranty on roofing and 12-gauge frames. 

30×30 Metal Building with Lean-To

We can add barn-style lean-tos to one or both sides of your 30×30 building. These lean-tos can be open or enclosed. If you don’t see the option you are looking for in our 3D design tool, give us a call for details.

Thousands of Happy Customers


“I am really happy with my metal Building from Alan’s Factory Outlet. After shopping around I found that Alan’s had the best product for the best price. The build your own building program on the website was easy to navigate. After purchase I was contacted by the Alan’s team to verify the details. They were courteous and very helpful, they wanted to ensure the details were right. Once delivery was set up the building was fully erected in about 12 hours. I love my new building”

– Michael, Alabama, 24×35 Metal Building

– Donna R., Georgia

Metal Building Uses

30×30 Pole Barn Alternative

Our 30×30 metal buildings are made out of steel poles that are bolted to the foundation, not wood poles that are sunk into the ground. So it isn’t completely correct to call it a pole barn. But our metal buildings are a cost-effective alternative.

Farmers often use prefab metal buildings for storing equipment, storing hay, and sheltering animals.

30×30 Shop

A 30×30 shop has almost 900 square feet of floor space. If you will be working in your shop, you will probably want to add insulation to help regulate the temperature. Another good idea is to choose a light-colored roof (like white) to maximize the energy efficiency of your shop building.

30×30 Shed

A 30×30 shed has plenty of space to store lawnmowers, tools, and other equipment you use in the backyard or farm.
