5 Inspiring 40×80 Barndominium Floor Plans With Shop


Barndos are increasingly popular home options for a myriad of reasons. For example, they allow you to reduce the average cost of a new build by about 30% per square foot for a single-story building.

On the other hand, they also allow you to affordably add large garages and workshops to your home, often for very little extra cost.

For example, the cost of adding an insulated workshop and garage to your barndominium can be as little as the cost of the foundation plus about $21 per square foot for building and insulation. 

Of course, if you’re putting in a barndo with a shop, you also want to consider factors like the living arrangements, the layout, how many shops you need, and what a usable space looks like.

These 5 inspiring 40×80 barndominium floor plans can help you figure out how a shop fits into your home and how to make the layout work for your living space. 

Factors Influencing 40×80 Barndo Floor Plans With Integrated Shops

Planning your barndominium means figuring out how you’ll use a space.

That means considering what you do in your daily life, how you intend to use a space, and what’s convenient as part of your daily life. 

Shop Size

How much shop space do you actually need? In general, it’s better to go too big than too small.

You can always have more empty space and more space to make things neat – but if your shop is too small, it’s going to be cluttered and will quickly stop being useable. That often means you’ll want to look at shop usage over 5-10 years and plan accordingly.

If you just want a room to work on vehicles, you can obviously just use the garage and have whatever space you need by pulling cars out.

On the other hand, if you’re looking for something like a private wood working space, you’ll have to consider how much space you actually need and plan accordingly.

Do you want your shop in your garage? Separate? Does it matter? Often, it’s a good plan to consider if you want to heat your shop.

If yes, then having a separate shop and garage is a good plan. That saves you from needing to invest in insulated garage doors for the garage. It also means you can get away with heating a smaller space – so you save money on bills. 

In addition, if you’ll be creating a large amount of dust or fine particulate in your shop, you probably don’t want it all over your cars.

Figuring out what you’re doing in your shop and what kinds of precautions you need to take for the rest of the home is important. 

Traffic Flow 

How easily can you move from one part of the home to another? Is it easy for guests to go to the toilet without passing through a private area?

Can you easily navigate around other people in hallways? Can you use spaces like kitchens with as many people as you want?

Do you have to take long walks through the house to use the toilet from a room you spend a lot of time in? 

Traffic flow means considering how you use the home and how you can optimize the home to cater to that usage. That might be ensuring that bedrooms have attached bathrooms if you spend a lot of time in private areas.

It might also mean ensuring that you have a half bath attached to your workshop, or making sure you have extra kitchen space for more people to work from. Good traffic flow generally just depends on how you use the home. 

Family Size 

The larger your family, the more you have to keep factors like private areas, noise, and bathrooms in mind. For example, if you have a family of 3, you’ll want to ensure that you have bathrooms and private space for everyone.

You’ll also want to make sure you have storage for everyone – including towels, bedsheets, etc., as those needs grow with a larger family. 


Your home should meet your needs. That means the priority in the home should be set around how you actually live.

If you frequently have guests over, you want a larger living space and entertainment area. On the other hand, if you mostly just have the house to yourself and spend a lot of time in your workshop or doing things at home, you’ll want to prioritize things like workshops, gyms, etc. 

Consider how you actually live and what’s convenient for that as well. For example, if you have small kids, you probably won’t want their sleeping areas right next to the living room – where you’re likely to wake them up by talking. 


You’ll always need more storage than you think. Therefore, it’s an extremely good idea to ensure that you work storage into your home plans.

Making sure bedrooms have closets, that you have a place to store food, that you have closets throughout the home, etc., is important.

That also holds true in your shop and garage, as having a dedicated storage area can free up a lot of clutter in already busy rooms – making your space that much nicer.
