Floor Plan Cost For 40×40 Barndominium

The actual cost for a 40×40 barndominium floor plan will depend on a variety of 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, cost of the concrete slab foundation, appliances, and more.

When finished, a 40×40 barndominium can cost $180,000-$360,000.  If you decide that you want to add on a garage, workshop, etc, you will have to figure in 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 out, you need to decide just how many bedrooms you might need for the children you are going to have.

Will they share a room as they get older or have their own 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?

All of these answers will figure in just how many square feet you will 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 side 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 are going to bring groceries in from there to the barndominium, you want to make sure that you do not have to walk across the entire barndominium to get to the kitchen.

When placing bathrooms that bedrooms are sharing, 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 different things that you need to consider when designing your 40×40 barndominium floor plan.

Take your time and get it the way that it will best suit your family and your lifestyle.

James HallBarndominiums Advisor

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.
