Why Should You Build a Corner Wall?

Corner walls are a great way to add character and dimension to a room. Not only do they create a unique focal point, but they also provide a practical solution for maximizing space.

How to Build a Corner Wall: A Step-by-Step Guide

Step 1: Measure and Plan

The first step in building a corner wall is to measure the space where it will go and plan the design. Consider factors such as the height and length of the wall, the materials you’ll need, and any electrical or plumbing lines that may need to be rerouted. Sketch the wall and make a list of the required materials, such as lumber, drywall, insulation, and screws. Once you have a solid plan in place, it’s time to move on to the next step.

Measure the Space Where It Will Go

Step 2: Cut the Lumber

Cut the lumber to the appropriate lengths according to your plan using a saw. Make sure the cuts are precise and even, as this will affect the stability and overall appearance of the wall. Wear appropriate safety gear, such as gloves and goggles, and use clamps to secure the lumber in place while cutting. Set aside the cut lumber until you’re ready to assemble the wall.

Step 3: Assemble the Frame

Using the cut lumber, assemble the frame of the corner wall. Start with the bottom plate, a horizontal piece of lumber that will sit on the floor and support the rest of the wall.

Then, attach vertical studs to the bottom plate at intervals of 16 inches in the center. Secure the top plate, another horizontal piece of lumber, to the top of the wall. Finally, attach angled studs to the corners, providing additional support and stability. Ensure the frame is level and secure before moving on to the next step.

Step 4: Install Sheathing and Insulation

Once the frame is assembled, it’s time to add sheathing and insulation. The sheathing is a layer of material covering the frame and providing a flat surface for attaching the exterior, such as drywall. Insulation is added between the studs to provide thermal and acoustic insulation. Cut the sheathing and insulation to fit and secure them to the frame. Make sure there are no gaps or holes in the insulation, as this will reduce its effectiveness.

Step 5: Add Drywall

With the frame, sheathing, and insulation in place, it’s time to add the drywall. Measure and cut the drywall to fit each section of the wall and attach it with screws. Make sure to leave a small gap between the drywall sheets to allow for expansion. Once all the drywall is attached, use a joint compound to fill in any gaps or holes and create a smooth surface.

Step 6: Finish the Wall

After installing the drywall, it’s time to finish the wall with paint, wallpaper, or any other desired material. This step lets you get creative and personalize your corner wall to match your aesthetic.

Step 7: Secure the Wall in Place

Finally, it’s time to secure the wall in its designated spot. Use a stud finder to locate the studs in the existing walls and attach the corner wall frame to them with screws. Make sure the wall is level and securely attached before considering it complete.

Following these steps, you can build a corner wall in your home or any other space. Remember to always measure and plan carefully, wear appropriate safety gear, and take your time to ensure each step is done correctly.

Building a corner wall may seem daunting initially, but with the right tools and techniques, you’ll have a sturdy and visually appealing addition to your space in no time.  So go ahead, unleash your inner DIY guru, and impress yourself with your newfound construction skills!

5 Considerations Things When You Need to Build a Corner Wall

1. Wall Size and Dimensions

When building a corner wall, one of the first considerations is the size and dimensions of the wall. You’ll need to decide how tall you want it to be and its width and length. It’s important to measure your space carefully before beginning construction, as this will help you determine the amount of materials you’ll need for the project. Additionally, make sure that your measurements are accurate to ensure a successful build.

2. Structural Stability

Another consideration when building a corner wall is structural stability. You’ll want to make sure that your wall is strong enough to support any additional weight that may be placed on it, such as shelves or furniture. If the wall isn’t properly reinforced with steel bars or other materials, it could collapse under pressure or become unstable over time.

3. Materials Needed

The type of materials needed for a corner wall will depend on its purpose and design. For example, if you’re looking for an aesthetically pleasing finish, then brick or stone may be better suited than wood or drywall. Additionally, consider whether you need insulation in order to provide soundproofing or temperature control within the space.

4. Cost Estimate

Cost is always important when undertaking any home improvement project, and building a corner wall is no exception. Make sure to research all of the necessary materials beforehand to get an accurate estimate of how much money you’ll need to complete the project successfully. Additionally, factor in any additional costs, such as labor, if you plan on hiring someone else to do the work for you.

5. Building Permits

Finally, depending on where you live, you may also need to obtain a building permit before starting construction on a corner wall. Check with your local government regulations beforehand so that you know exactly what paperwork needs to be filled out in order for your project to go ahead without any issues down the line.

5 Benefits of Building a Corner Wall

1. Increased Privacy

Building a corner wall can provide increased privacy for your home or property. Corner walls are typically taller than traditional walls, so they can help to block out noise and unwanted views from the street or neighboring properties. Additionally, corner walls can be built with various materials, such as brick, stone, or wood, adding a unique aesthetic to your property.

2. Enhanced Security

A corner wall can also help to enhance security on your property. Corner walls are typically very sturdy and difficult to breach, so they can provide an effective barrier against intruders or burglars. Additionally, corner walls can be topped with spikes or other deterrents, making it even more difficult for someone to access your property.

3. Improved Curb Appeal

Building a corner wall can also help improve your property’s overall curb appeal. Corner walls are often quite attractive and can add a touch of elegance and sophistication to any home or landscape design. Additionally, you may be able to customize your corner wall with different colors or materials that will match the existing architectural style of your home or property.

4. Added Property Value

Installing a corner wall on your property can also increase its value if you decide to sell. A well-built corner wall will make your property more attractive and indicate that it is well-maintained and secure – both of which will attract potential buyers looking for a safe and aesthetically pleasing place to live.

5. Wind Protection

Finally, building a corner wall on your property can also protect you from strong winds that may cause damage during storms or high wind conditions. Corner walls act as windbreaks by blocking strong gusts from reaching vulnerable areas of the yard, such as gardens, patios, decks, etc., thus helping to protect them from damage during extreme weather conditions


Building a corner wall is a manageable project that can add value and functionality to your space. By following these steps and taking care to measure and plan, cut lumber precisely, assemble the frame, add sheathing and insulation, and finish the wall, you can create a beautiful and practical corner wall that meets your needs and preferences.

Remember to take safety precautions, wear protective gear, and seek necessary help. With a little patience and persistence, you’ll soon have a corner wall to be proud of. Thanks for reading our post about how to build a corner wall.
