A 40×80 structure can have many applications, but how much will a building of this size cost you? The cost of your building will depend on a variety of factors, including:

  • The manufacturer
  • Your location
  • Any upgrades or customizations you may want

Keep in mind that these costs are just for the building itself. This cost does not include:

Installation and Interior Finishes

Some metal building kits are DIY-friendly, but if you’re building a barndo or something more complicated than a simple storage building, you may want to hire a professional to install and finish your building.

Construction costs can range from $5-$10 per square foot. Factors that will affect the cost include:

  • Labor. The larger the building, the higher the labor costs. Labor costs will also vary based on location and the complexity of the job.
  • Insulation. If your building is going to be insulated, construction costs will be higher.
  • Doors and windows. The more windows and doors you have, the higher the cost will be.
  • Appliances and other finishes. If you’re using your metal building as a home or for a workshop, you will likely need appliances and other finishes, such as countertops, cabinets, plumbing fixtures and an electric system. All of these extras will add to the overall cost of the project.
  • Utilities. If you need to run electricity and water/sewer to the building, the construction costs will be higher.

The Foundation

A 40×80 metal building will need a foundation. The most common type of foundation used for these buildings is a concrete slab. Concrete slabs can cost $6 or more per square foot and are the simplest type of foundation for a building of this size.

Pier, floating slab and curb foundations will likely cost more to build.

Residential homes are much different than when you use a metal buildings for livestock or agricultural uses. You want a home that is unique and functional, and with 3,200 square feet of space, there’s a lot to love with a 40×80 metal building plan.

  • Space: The average home size in the US is 2,480 square feet. However, walls and barriers make these homes feel smaller. When you step into a 3,200-square-foot metal building, you enjoy massive open spaces that help make your residence feel larger and more functional.
  • Windows: The strength and durability of metal allow homeowners to be creative with their homes in ways that aren’t possible with other building materials. For example, metal can support massive windows and doors, allowing you to maximize your landscape and let in an abundance of natural light.
  • Cost-effective: As outlined in the previous section, metal buildings are cost-effective and produce far less waste than their wooden or concrete counterparts.
  • Structurally sound: Fires, tornadoes and hurricanes can destroy a home that you worked hard to buy in a matter of seconds. Metal buildings provide high levels of resistance that allow them to remain standing even after severe weather and natural disasters.

Metal vs. Wood Benefits

Wooden structures are everywhere, but there are better options available. Metal structures are becoming increasingly popular, especially the 40×80 metal building kit. Contractors and builders agree metal has a lot of advantages:

  • Higher durability and strength: Severe weather has potential homeowners worried about their building’s maximum snow load, strong winds and hurricanes. Metal buildings are lighter yet stronger than their wooden counterparts, allowing them to withstand high winds, heavy snow and even earthquakes.
  • Moisture resistant: Metal, especially if the metal builder you choose uses zinc coating or powder treatments, can withstand moisture exceptionally well. You don’t need to worry about metal rotting as you do with wood.
  • Pest resistant: Pests are another major concern, especially termites, which can destroy a home if they’re not found quickly. Metal buildings are resistant to pests, including wood-boring beetles, termites and carpenter ants.
  • Produces less waste: Construction produces a lot of waste. A regular wooden home of 2,000 square feet produces 1,500 – 3,700 pounds of solid-sawn wood waste and an additional 1,000 – 1,800 pounds of engineered wood waste. Metal buildings do not produce nearly as much waste, making them an eco-friendly option for your build.
  • Open floorplans: Large, open spaces are possible thanks to steel ceiling joists that can support more weight and allow for open spaces. Wood cannot match the level of strength that steel offers for open floorplans.
  • High eaves: Depending on your needs, the eave height can allow for a top level with living quarters and a bottom level for a garage, workshop or commercial activities. You can also add in skylights or large walled windows.

Add in the fact that metal is fire resistant, and it’s clear that a metal building has a lot of advantages over its wooden counterparts.

A 40×80 metal building with living quarters offers you exceptional quality, durability and many benefits. If you want to build a large space, offering 3,200 square feet of space, 40×80 metal barndominium plans are a great option.
