Angled Wall Framing Techniques

If you're thinking about dividing your basement into individual rooms by putting up some walls, you can make more useful space by dividing your basement into rooms such as a home office or bedroom. This also gives additional living space for a father or mother who is getting older, and needs you to care for them. One important skill you need if you want to create one or more rooms yourself is to know angled wall framing techniques.

Type of Framing

Angled wall framing is easier than you may think.

Framing a wall requires a basic knowledge of and skills in carpentry. It is easier to frame interior walls that are not load-bearing, than exterior walls near the foundation of your basement.


Correct measurement ensure walls connect to each other at an accurate 90-degree angle; the walls must be squared against each other. One useful tool is a T-square. A T-square is often used on a drafting board to draw lines at a 90-degree angle to each other. It can also be used to draw lines on a floor to position two walls to come together at a ninety degree angle.


Buy 2-by-4 pressure-treated lumber. Mark the wood every 16 inches for studs. Studs are upright support pieces to which wall material is attached. Make a line 3/4-inch for each side of the stud mark points from your measuring tape. Mark each board at the same position for each of the studs so they line up for the top and bottom of the well.


Determine stud length by measuring the height of a room. Use a measuring tape from the floor to the ceiling. Subtract 3 ½ inches from your measured distance to get a final length. Cut seven studs for a wall section 8 feet wide. Nail the studs to the top and bottom plate of the 2-by-4s.

Chalk Line

Snap a chalk line on the ceiling and floor, the length of the wall. Use a plumb bob from the ceiling to the floor, for where to place the chalk line on the floor.

Wall Raising and Securing

Raise the wall and position the top and bottom of the wall along the chalk lines. Secure the top of the wall to the ceiling joist and use shims to fill in any gaps. Secure the bottom plates to the concrete floor with masonry screws.

Second Wall

Use a T-square to draw ceiling and floor lines at a 90-degree angles to the first wall. Construct the second wall in the same manner, and move it into position at 90 degrees to the first wall. Attach the second wall to the floor and ceiling the same way, butting the edge of the first wall flush against the edge of the second wall.
