Types of Interior Wall
There are two main types of interior walls – a partition wall and a load bearing wall. Below, we will take a look at the differences between these two.
Partition Wall
A partition wall is a simple wall that does not hold any of the weight of the house. When removing a partition wall, you won’t usually need to install an RSJ as these walls are not needed to hold up the house and keep the house safe.
A partition wall is the easiest type of wall to remove and can usually be removed quite quickly. These walls tend to separate two adjacent rooms, such as a living room and a dining room.
Load Bearing Wall
A load bearing wall holds up the weight of the house. You can’t simply remove a load bearing wall as it can be dangerous and will affect the structural aspects of the home.
When removing a load bearing wall, there are a lot of calculations involved. These calculations enable the tradesperson to figure out which an RSJ needs to be installed to support the weight of the structure.
Benefits of Removing an Internal Wall
There are several benefits to removing an internal wall in your home. Below is a list of the main benefits of this type of work:
Additional Space

This can provide you with a lot more opportunities when it comes to decorating and furnishing your home.
Brighten the Space
Walls can create shadows in the home, and small rooms can appear dull and dark. When you remove an internal wall to open out your living space, it can really brighten the space up and make it look a lot more inviting.
Transform the Home
Removing internal walls can completely transform your home and make it look completely different. Modern homes are adopting the open plan living space idea more and more. With this in mind, removing an internal wall can modernise your home and make it seem like a completely different home.

Q: Can I remove my internal wall myself?
A: You can remove a partition wall if you would like to yourself. However, you should always have someone to work with you for safety reasons. Since it’s such a large job, many people prefer to leave it to professionals to do this type of work rather than attempt it as a DIY job.
If the wall is a load bearing wall, you should never attempt to remove this type of wall yourself.

Q: How do I know if my wall is a load bearing wall?
A: There are several ways for you to confirm whether or not a wall is load bearing. One of the simplest ways to identify a load bearing wall is the check if the wall is parallel to the floor joists. If it is, then it is probably not a load bearing wall.
Load bearing walls typically face the joists at a 90-degree angle. If your home has a basement, you can identify the load bearing wall by going down into the basement and seeing if there is a support wall or a beam facing the same way. In this case, it may be a load bearing wall.
If you are unsure about whether or not the wall you want to remove is load bearing, then you should contact a structural engineer or an architect who can come and inspect the wall and determine whether it is load bearing or not.
