How to Frame a Half Wall Room Divider

A half-wall can provide visual separation between rooms in an open floor plan. However, a half-wall does not close off a room, permitting communication between occupants of different rooms. Since a half-wall does not have to bear the weight of the home’s structural members, it can be constructed more easily thanĀ  a load-bearing wall. You can frame a half-wall with only basic carpentry supplies and tools.

For this job you will needĀ 

Stud finder

Measuring tape

Carpenters level

Lumber, 2″x 4″

Circular saw

Drill

4″ Wood Screws

Electric Screwdriver

To begin, you need to find a stud in the wall adjacent to the half-wall with a stud finder. Measure the length of the area where you will place the half-wall with a measuring tape. Check the floor with a carpenter’s level to make sure it’s level. Measure two sections of 2″x 4″ pressure-treated lumber to the length of the half=wall. Cut the sections with a circular saw to form the top and bottom plates.

Next you’ll want to determine the height of the half-wall; this type of divider typically is between 30 to 36 inches tall. Measure and cut sections of 2” x 4” lumber 4″ shorter than the height of the half-wall to form the studs. You need one stud for each end of the wall, plus one stud for each 16″ of interior wall length. Lie the top and bottom plates on their 2″ sides. Place one stud between the plates at each end, and at 16″ intervals between the end studs.

Drill pilot holes through the top and bottom plates into the ends of the studs with a drill; the pilot holes should be slightly smaller than the diameter of the wood screw shafts. Insert a tighten 4″ wood screws through the pilot holes with an electric screwdriver to secure the half-wall frame.

Stand the half-wall in the desired location with one end against the adjacent wall. Drill pilot holes through the bottom plate into the sub floor at 4″ intervals. Insert and tighten 4″ wood screws to secure the half-wall to the floor. Check the half-wall with a carpenter’s level to ensure the wall is vertical. Drill pilot holes through the end stud into the adjacent wall stud at 4″ intervals. Insert and tighten 4″ wood through the pilot holes. You are now ready to drywall.
