How to build a corner shelf frame

Fitting a shelf into the corner of a room is a great way to add storage space. You can make the corner shelves as large or as small as required, depending whether you want to use them for a potted plant, an ornament or to stand a television on. The benefits of a constructing a corner shelf is that you have two walls for added strength.

Skill level:

Things you need

  • 18 mm MDF or plywood sheet
  • 50 mm by 25 mm sawn wood batten
  • Tape measure
  • Saw
  • Drill
  • Masonry and wood drill bits
  • Wall plugs and screws
  • Screwdriver
  • Spirit level
  • Bradawl

  1. 1

    Cut a triangular piece of wood from the sheet of MDF or plywood that will be used for the shelf. The edges of the triangle that will be against the walls should be straight, but the front of the shelf can be curved or shaped as required.

  2. 2

    Measure the sides of the shelf that will be against the wall, and cut two 50 mm by 25 mm battens to match. Reduce the length of the battens by approximately 20 mm, so they won't be as visible underneath the shelf. One of the battens should be cut an additional 25 mm shorter than its measured length to take into account the other batten that will go all the way into the corner.

  3. 3

    Drill mounting holes through each of the battens at regular intervals. The number of mounting holes required will depend on the size of the shelf, but each batten should have at least one hole near either end.

  4. 4

    Place the longer of your two battens against the wall where you want to mount the shelf, and use the spirit level to ensure it is straight. Mark the wall through its mounting holes using the bradawl.

  5. 5

    Drill the wall using a masonry drill bit of adequate size for your wall plugs and screws. Push the wall plugs fully into the wall, and offer up the batten. Screw the batten to the wall.

  6. 6

    Offer up the shorter batten to the adjacent wall so it butts-up to the existing batten. Ensure it's aligned with the existing batten where the two meet, and use the spirit level to make sure it is straight. Mark the wall with the bradawl, drill the holes, insert the plugs and screw the batten to the wall.

  7. 7

    Place the shelf on top of the two battens. A larger shelf might support itself, but it's recommended to screw the shelf to the two battens from above.

Tips and warnings

  • For extra strength, run a bead of wood glue along the top of the battens before putting the shelf on top of them.
