Interior walls are necessary when it comes to the indoor structure of the home. Whether you are building your home office or refinishing an attic, you will need to build a wall or two. From dampening noise to sequestering heating and cooling, walls have multiple uses and benefits. In this article, we will provide you with the information you need. Let’s get started!

When it comes to walls, they can be of two types:
- Load-bearing walls
- Non-load bearing Walls
Load-bearing walls not only carry their own weight, but they also bear the weight of the materials above them. On the other hand, non-load-bearing walls only carry their own weight.
Usually, interior walls that divide the room and create small spaces are non-load bearing.
The non-load-bearing interior walls consist of the following parts:
- Bottom plate
- Top plate
The horizontal bottom plate rests on and connects the wall with the floor. Similar to the bottom plate, the top plate connects the wall to the ceiling and to the tops of the vertical joints. The studs are 2x4s that are spaced almost 40 cm apart. Drywall is fastened to the back and the front of the wall.
Preparing for your project
A stud wall consists of a frame of timber that is attached to the walls, ceiling, and floor with the help of metal studs. Building a stud wall is a fairly simple job. However, there are a few things that you have to check before you begin.
Ensure you are compliant
Firstly, check with your local authorities to ensure that the work you will be doing conforms to the building regulations pertaining to ventilation, light, fire resistance, etc. The next thing is to organize the heating, lighting, and – if necessary – the plumbing for the new room.
Measure & Plan
Measure the length of the wall. Next, measure the height of the ceiling as well. To find out the number of studs you will need, divide the length by 40 cm. You will need two more studs to use as ‘end studs’ that you will place at the ends of your wall.
If the ceiling is 2.4m or less, you can use 2.4m lumber for the studs. If the ceiling height is over 2.4m, then you would need 3.1m lumber. To select the top and bottom plate, you will need to keep the wall length in mind.
How to build an interior wall step-by-step
Things You Will Need
- Speed square
- Cordless drill
- Circular saw
- Step ladder
- Electric mitre saw
- Laser level
- Tape measure
- Club hammer
- Drywall knife
- Carpenter’s pencil
- Painting supplies (cover, tray, roller frame) – Optional
- 9 two-by-fours
- 4 Drywall sheets
- Galvanized nails
- Drywall screws
- Drywall joint compound
- Drywall primer
- Paper drywall tape
- Interior paint – Optional
1. Find a Place for the Bottom Plate
Find a solid spot on the floor where you will fasten the bottom plate. If the floor is concrete, it is solid enough. If there are wood joists beneath a floor covering, then you should place the wall directly perpendicular to the floor joist or a parallel joist.
2. Marks the Plates
Place the bottom and top plates next to each other. With the help of a tape measure, mark the stud positions on them. Mark two places at either side for the end studs. In between these two, mark five positions, keeping them 40 cm apart, on-centre.
Make the marks on both the top and the bottom plate. Use a spirit level, such as a string line, to ensure that your markings and levelling on the existing wall are correct.
3. Attach the Bottom & Top Plates
If the floor is concrete, attach the bottom plate using concrete nails to the floor. In the case of wooden floor systems, fasten the bottom plate with a hammer and nails to the floor. You have to attach the top plate directly above the bottom one. Connect it directly on one joist or across perpendicular ceiling joists. Line up the plate, and nail it firmly into place.
4. Cut & Nail the Studs
Measure from the bottom of the ceiling plate to the top of the floor plate. Cut the studs of this exact measurement using the electric mitre saw. Make sure to mark and number the studs so that you know where each one will go later. Using a hammer and nails, attach each stud firmly into position.
5. Hang the Drywall
Once you have positioned the studs, it is time to hang the drywall. Hang it horizontally on the studs. Fasten the drywall sheets with the help of drywall screws and a cordless drill. Follow the building code when it comes to the penetration distance of the screws.
6. Fill the Seams
You will have drywall seams, depending on the number of drywall sheets you used. Fill the seam with the joint compound. After the compound dries, check for gaps. If there are any, fill them. To fill the screw holes, you will need to use the joint compound and the drywall knife.
7. Insulating the Walls
If you fit slab insulation between the studs before you attach the drywall sheets, you will be able to enjoy better heat and sound insulation. To ensure that that electric cables don’t overheat, we recommend that you clip a PVC conduit to the studs and run the wire through it.
What is great about stud walls is that they are not load-bearing. This means that you create a doorway wherever you want, and in the shape of your choice. However, we recommend that you place the door against one of the end studs as this will brace the door frame more firmly.
8. Painting the Wall
To make the wall look presentable for the time being until you decorate it properly, you should paint it. Firstly, add some primer onto the paint tray and then apply it to the roller foam. Roll it evenly all over the drywall.
Let the primer dry for over 24 hours before painting the wall. You will probably need two or three coats of paint, so make sure you let each coat dry completely before applying the next coat.
