Amazing 30x40 Barndominium Floor Plans - What to Consider (2023)

Living in one’s own house is the ultimate aim of most people and for various reasons. Some believe that it makes more financial sense to pay monthly for a mortgage on a property their children can inherit. Others want to stay put instead of moving from one apartment to another.

Whatever their stories may be, one common thread runs through all of them – the wish to own their dream home. They have two options: purchase one that is already built and waiting for an occupant, or design and build their own.

If you choose the latter, we highly recommend a barndominium. This barn-like structure is perfect for anyone who wants to have the final say regarding the layout of their home.

A barndominium is affordable, energy-efficient, and easy to maintain. Wide-open spaces and high ceilings provide ample natural light and air circulation. The structure offers flexibility to suit your unique needs. We have curated 9 30×40 Barndominium Floor Plans for living spaces with an average size suitable for small families, couples, empty-nesters, or siblings. Each is thoughtfully designed and will jumpstart your creativity when it comes to designing your own abode.

30×40 Barndominium Floor Plans Things to Consider

Before planning and designing your very own floor plan, you must factor in some important aspects.


Who is this new home for? The answer to this question is your foundation for the design and layout of your living space.

A barndo with a 30’ x 40’ floor area is best for a small family with one or two children. The parents can have the master’s suite with its own bathroom and walk-in closet, while each child may occupy their own bedroom. They have the option to share a bathroom to maximize space.

Newlyweds will find this size perfect for starting their new life together and getting ready to create their own brood.

The dimensions are perfect for retired couples as well. A bungalow-type design, with the option to keep common areas open, facilitates mobility.


If you are fortunate to own the land in a place with an amazing view, consider using large windows and installing them strategically. This way, you can still enjoy the panoramic landscape when the weather requires you to stay indoors.

Add a back porch where you can lounge on lazy weekends, or make space for a play area for the kids. You can consider having a sliding door leading to a balcony from the master’s bedroom as well.

Traffic Flow

Movement within the household depends on the lifestyle and profile of its occupants. For instance, kids’ bedrooms need to be in close proximity to their parents’ bedrooms. On the other hand, teenagers would want more privacy, so their quarters should be located a bit farther.

Common areas, such as the living room, dining room, and kitchen must be accessible to all members of the household. This is an important consideration for retired couples who need unobstructed entries and exits to all areas of the house.

Closets and Storage

Couples and small families normally don’t have much stuff to necessitate plenty of storage space. So, bedroom closets might also have sufficient space to store out-of-season clothing, as well as towels and linen.

However, you should still include a utility room for cleaning appliances and repair equipment. This can double as storage for holiday décor, luggage, and travel or party accessories.

You may also take advantage of the walls and ceiling of the laundry area. It’s a great place to store bulky items such as comforters, curtains, and winter jackets.


The beauty of owning a barndominium is its flexibility, both inside and out. For the exterior, you can choose the kind of parking space you want depending on your needs. It can be a carport, a garage, or a parking pad.

If you’d rather ride a bicycle than drive a car, then have a porch instead. What you need to keep in mind is that the dimensions of your parking area must be determined before designing the floor plan. It will definitely take up space.

30×40 Barndominium Kits

If you’re looking to start building your barndominium, one of the first things to do is to get a quote for the metal shell or barndominium kit. By using the quote service below, you’ll get connected with a barndominium kit provider within a few hours at most. Prefabricated barndominium kits mean that the metal shell that makes up your barndo is produced off-site, then it’s brough to you for erection and assembly. While some builders will help you order the barndominium kit, we suggest doing it separately to avoid a potential markup on the barndominium kit.

That’s it! By using the tool above you’ll get connected with a kit provider for 30×40 barndominium kits.
