How Do You Frame Inside a Barndominium

Framing inside a barndominium may seem like a daunting task, unless you have a general understanding of construction framing best practices for other types of projects, like residential or commercial spaces. There are few differences between the type of framing required for a barndominium and one of those building types; however, there are some things that you’ll need to know before you get started. 

To frame inside a barndominium, you’ll need to have a design plan and an understanding of building codes. Once your design is set, you’ll need to spray the exterior walls with installation, build your walls, and raise them. Then you’ll need to install your ceiling beams and complete all finishes. 

The rest of this article will delve deeper into each of these steps, so keep reading to learn more. 

Design Your Layout

When designing any new structure, you’ll want to be sure to have a solid layout before you begin. This will include things such as room count, room type, and the placement of these areas. 

You’ll also need to plan to account for the standard means of egress per room according to your city or state’s building regulations, meaning that you’ll need to have a certain number of windows and doors depending on what the room will be used for. 

When determining your room size and count, you’ll need to take a look at the square footage of the total space and consider the placement of the rooms. How much space do you want to designate for the living area, and how much will be for your working area? Do you have enough room to build up a second floor, or will all living and working areas be on the same level?

Spray Foam Insulation on the Exterior Walls

Once you’ve decided on a layout, it’s time to insulate the exterior walls of your barndominium. Insulating the exterior walls before adding any framing is a good idea because it will allow you to reach all sides of the exterior walls without any wood or other materials getting in the way. 

Spray foam insulation is a great option when building out a barndominium with metal exterior walls because it creates an air-tight seal that is less permeable than other modes of insulation. It also provides a layer of protection from moisture, which can collect on metal surfaces. To prevent moisture from damaging your interior walls, the spray foam needs to be tightly bonded to the metal structure. 

Additionally, adding a layer of insulation and leaving a gap for air will further aid in insulating your home. The space between the insulation on the exterior wall and the framed interior wall will create an air pocket, which will act as secondary insulation, keeping you cool in the summer and warm in the winter. 

Build Out the Walls

Once the insulation has dried, you can start framing the interior walls of your barndominium. Something important to remember is that there are no special regulations when framing a barndominium. You’ll follow all standard residential building codes per the city or state you’re planning to build in. 

To build out your barndominium walls, you’ll want to start with the length and height of the walls for each room, then add the studs, and then frame out the windows and doors. 

Frame the Length and Height of the Walls

The easiest way to frame the walls of your barndominium is to start by building them on the floor and then lifting them into place. Start by completing a full frame of the wall using two 2x4s. You’ll want to be sure to build out the frame first, rather than building off of the metal walls, because this can cause damage to your drywall over time. The metal walls may bend and sway slightly due to wind, which can crack your drywall. 

Add the Studs

Once you have the frame in place, you’ll want to add the studs. Studs are a crucial part of any framing job because they are what you’ll attach the drywall to during the finishing process of your construction job. They also provide a support structure so that you can hang things on your walls once they’re finished. 

The industry standard for residential buildings is to place a 2×4 stud every 16 inches along your wall. 

Frame out the Windows and Doors

Once you have the perimeter of the wall in place, it’s time to frame out the windows and doors. You will need to measure the height and width of the doors and windows, and then frame them out using 2x4s around their perimeter. You may need to cut the studs you’ve put into place to fit the window and door openings in the correct place. 

Raise the Walls

Now that the frame of the wall has been completed, it’s time to raise the wall and secure it in place. To do this, you’ll need more than one person to lift the structure evenly so that it doesn’t bend. Once you’ve raised the wall, you will need to secure it into the concrete slab or foundation floor to prevent it from moving. Start with the exterior frame and then move on to the interior walls so that you have something to connect them to. 

Install Ceiling Beams and Joists

Once you have framed out the perimeters of your walls, you’ll need to add the required ceiling beams and joists to support your ceiling. A common ceiling framing method is to use three 2×12 beams nailed together at regular intervals across the length of your room. Once you’ve installed the beams, install ceiling joists perpendicularly across the top of the frame using 2x4s. 

Add the Framing Finishes

Now that your walls and ceiling are framed in, it’s time to add some necessary framing finishes. This will save you time and energy in the long run, preventing you from having to cut into any drywall or insulation you put into place to add the necessary plumbing and electrical fixtures for the room. These finishes can save you time and money as you complete the build-out of your barndominium.

Plumbing/Electrical Boxes

You will need to add all plumbing and electrical fittings ahead of your contractors, so they know where to run their conduit. You’ll want to consider the placement of these boxes according to city and state building regulations. If you’re unsure, your local contractor should be able to help. Doing so will speed up the finishing process once it’s time to install drywall and complete all other building finishes.


Framing the inside of your barndominium doesn’t have to be a tough job. If you’re familiar with standard practices for framing a residential building, you should be able to easily frame the interior of your barndo in no time. 

The first thing you’ll need to do is design the layout, making sure that the room size and placement go along with your vision. You’ll need to define what will be the working space and what will be living space. Next, you’ll want to spray foam insulation along the inside of the exterior walls to create an air-tight seal and prevent moisture. 

Once that’s done, you’ll frame out the perimeter of the walls, add the studs, and frame out your doors and windows. Next, raise the walls and secure them to the concrete slab floor. Add your ceiling beams and joists, and any framing finishes to complete the interior framing job.
