Types of Interior Wall

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.

08 Internal Wall

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.

FAQs

Q: Do I need planning permission to remove an internal wall?

However, if your home is a listed building, then you will need to obtain planning permission. If you live in a listed building, you will have to pay around £200 to apply for planning permission.

Q: Do I need to follow building regulations when removing an internal wall?

A: If you are removing a load bearing wall, you will need to adhere to building regulations rules. When you apply for building approval through your local authority, this can cost up to £650.

You will need to have inspections throughout the process to ensure that the work is complying with building regulations. This will also offer reassurance that the structure of your home remains safe and sound.

Q: Do I need a structural engineer when removing an interior wall?

A: If you are removing a load bearing wall, you will need to hire an architect or a structural engineer as they will need to work out the calculations needed to install an RSJ. This is necessary so that the relevant type of support is put in place to ensure your home remains structurally sound and safe.

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.

There are many calculations needed to remove a load bearing wall to ensure that the appropriate type of support is put in place to support the structure of your home.

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.
