5 Super Versatile 30×40 Barndominium Floor Plan Designs


If you’re putting up a barndominium, you’ll quickly find that 30×40 is the most common size for building kits.

While there are plenty of other building kit sizes, and you can always customize your barndo to whatever you want it to be, it’s a good idea to get a feel for what a 30×40 barndominium can look like.

These versatile 30×40 barndominium floor plan designs will give you a good idea of how to use that space, how much you can fit into it, and what it’s good for. 

These plans are designed to be versatile. This means you can tweak them to suit the needs of a growing family, to fit your teenagers, or re-arrange to meet the needs of a retired couple.

Whatever you want, the 30×40 barndominium can easily meet those needs, providing it offers enough space for you and your family. 

These floor plans are great examples of what you can do with a 30×40 barndo.  

6 30×40 Barndominium Floor Plan Factors

There are plenty of things to consider about your floor plan and your home layout before you jump into it.

Those factors will affect how practical your home is, what you need, and what your home will be like when you’re living in it. 

1. Family Size 

Your barndo will be your home for a long time. In most cases, you should plan for your home to suit your family size for the next 5-10 years at the minimum. This means that if you’re newlywed and looking to have kids, you should plan for that when scoping out your barndo.

If your kids will be teenagers before you leave the space, you should also plan for that. The larger your family, the more space you’ll need.

In addition, a 30×40 home is suitable for about a maximum of 2 kids once those kids reach about age 10. This means that if you’re planning on more kids or will stay in the home past that age, you’ll want to either get a larger home or plan on an addition. 

2. Style

Style affects a great deal about the look and feel of a home. For example, there’s a big difference between a 30×40 home with a garage built in and one with a semi-detached garage or a breezeway and detached workshop.

Your barndominium will allow for a lot of style choices ranging from traditional to contemporary. For example, you could have a second story with traditional ceiling heights or leave half the top floor open for a vaulting living area with 18’ or higher ceilings. 

3. Cars 

How many cars do you have? Do you want them indoors?

Planning a garage into your barndominium is usually the way to go. That’s true even if you’re planning to put the barndo in as a separate structure connected by a porch or breezeway.

What else? If you have a growing family, you might want to consider a third car area in your garage for when your teen wants their own car! 

4. Traffic Flow 

How do people move around your home? What areas have heavy traffic? How is access from bedrooms to bathrooms?

What about from social areas to bathrooms? Do workflows in kitchens make sense? Are areas prioritized based on how much you use them?

For example, if you frequently socialize and rarely cook, you’ll want a larger living space with a kitchenette, on the other hand, if your family frequently cooks together, a spacious kitchen with plenty of room to cook together is a good thing.

You’ll also want to consider how you access bedrooms, patios, balconies, and other areas. For instance, if your guests have to walk through a bedroom to get to a bathroom, you’ll probably want to reconsider the floor plan. 

5. Storage 

Storage is an often overlooked part of the floor plan, but the more of it you have, the better.

It’s always a good idea to look for areas that have storage worked in. Whether that’s in the garage, in storage cupboards, or in pantries is up to you.

However, the best floor plans have all three worked in – because you will use it. That’s also true with closets – although you can always add wardrobes if you don’t want to focus too much on closet space. 

6. Lifestyle 

What do you do with your free time? If that’s hobbies that require a workshop or floorspace, you’ll want to consider that when looking for a barndominium floor plan. For example, having a workshop or open floor space for sports can add a lot of value.

On the other hand, if you’re retiring and primarily spend time gardening, you might not want that extra space and might instead prefer to have a covered outdoor area.

Consider how you actually use your home, what every member of the family likes to do, and what your lifestyle actually is.

Sometimes, that can also mean looking at the layout of your home. For example, if one person has a loud hobby – you can add to the quality of life by separating the workshop, adding a breezeway, and then having a noise barrier between the home and their space.

If you have small children but still like to socialize, adding space between the bedroom and living area can ensure kids can sleep soundly while you have guests.

Keeping lifestyle in mind when choosing a floor plan will do a lot for your home.
