Are you outgrowing your current home but cannot find one that meets your family’s needs and lifestyle?

Then you need to consider building the home that you have designed yourself.  If you want a unique home, consider a barndominium.

Depending on how it is designed, you could have your master suite plus two to three more bedrooms.  This size barndominium would give you approximately 2,000 square feet of living space.

But where do you get a 40×40 barndominium floor plan that would fit your needs?  This is easy to answer.  You design it yourself; choose one from the builder or online.  The possibilities are endless.

This article will also answer the second most asked question; what is the cost?

The article will also share with you not just one 40×40 barndominium floor plan but eight of them to help you get an idea of what you want in your barndominium.  It will also cover what it takes to design your own.

Key Takeaways:

  • A 40×40 barndominium has approximately 2,000 square feet

  • The larger size will make it appealing to buyers if you choose to sell

Floor Plan Cost For 40×40 Barndominium

The actual cost for a 40×40 barndominium floor plan will depend on various things.  One is the actual square footage.

The average price is $20-$100 per square foot.  You might think that building one would be inexpensive since you can get it for $20 per square foot, but that is just a shell of a barndominium.

It generally includes only the exterior walls, roof, and beams and nothing else.

You still have to figure in the cost to build your barndominium, insulation, flooring, the cost of concrete slab foundation, appliances, and more.

When finished, a 40×40 barndominium can cost $180,000-$360,000.  If you add a garage, workshop, etc., you will have to figure out that cost.

For example, if you want to add in a workshop, that can average $35-$60 per square foot.

40×40 Barndominium Floor Plans: Design On Your Own

When you design your 40×40 barndominium floor plans, there are many factors to consider.

One of the main things to consider is the space that you need.  If you are a young couple just starting, you need to decide just how many bedrooms you might need for the children you will have.

Will they share a room as they age or have their room?

Will you need a guest bedroom, a study, or a room for a home office?

Will you want a large kitchen and dining space or just a large kitchen with an island?

How much space will you want for your living space?

These answers will figure out just how many square feet you need.

You will also need to consider your lifestyle.  Do you want your children’s bedrooms near yours, or would you want them on one side of the barndominium and the master suite on the other to give everyone some privacy?

If someone works the third shift, they may want their bedroom away from the rooms where the family gathers and the kitchen so they can sleep undisturbed.

If you are building a garage and bringing groceries in from there to the barndominium, you want to ensure that you do not have to walk across the entire barndominium to get to the kitchen.

When placing shared bathrooms, will it be a jack-and-jill bathroom, or will they have to come out of the bedroom to get to the bathroom?

These are just some of the many things you must consider when designing your 40×40 barndominium floor plan.

Take your time and get it the way best suits your family and your lifestyle.

They have divided this barndominium in half, per se, with the kitchen, dining, and living space on one side and the bedrooms on the other.

It is not a jack-and-jill bathroom.

Example 2 Plan 173

There is no formal dining area, but there is a bar with seating for four.

Example 3 Plan 174

This 40×40 barndominium has two bedrooms, one of which is a large master suite with a walk-in closet that measures 10×9 with a bathroom that is 10×24.

Example 7 Plan 178

The kitchen has the appliances and counter space with the sink along two walls made like an L shape.

I'm James, your barndominiums advisor. Several years ago, I had no idea what barndominiums were. Although I'd spent over 10 years in the construction industry, the first time I heard about barndominiums was when I saw my neighbor building a new-style home. That was the first barndominium I've ever seen, and I found it so fascinating that I wanted to learn more about them.
