Corner shelves are a different method of providing storage to a room of any size. Where book shelves that require wall space may be too dominating in smaller rooms, corner shelves can suit any room size and can provide additional storage space. While some corner shelves are small, displaying crafts or collections, larger corner shelves may hold books, clothing or even heavy-duty machinery in the garage. Making a large corner shelf is easy and all of the supplies can be purchased in a hardware shop.

Things you need

  • Measuring tape
  • Timber for the shelf
  • Large protractor
  • Pencil
  • 4 wall brackets
  • Paint or stain
  • Screws for installation
  • Screwdriver
  • Saw
  • Sandpaper

  1. 1

    Measure the wall where the large corner shelf will be attached. It is important that the large corner shelf will not interfere with windows or any other furniture. Write the measurements down of how large the shelf will be, using the wall as a guide.

  2. 2

    Hold the protractor up against the corner of the wall to ensure it is an even 90 degrees.

  3. 3

    Transfer the measurements onto the timber that will be used for the shelf. Use the protractor to create the appropriate angle when drawing the shelf on the timber. Use the wall measurements to make two large, perpendicular lines.

  4. 4

    Connect the two ends, so the shelf becomes a triangle. The design, however, is up to the designer. It could be a simple straight line, a half-moon circle, small wave design or a spontaneous design.

  5. 5

    Cut the shelf using a saw. Sandpaper the edges and surface smooth to avoid cracks and splinters.

  6. 6

    Paint, stain or decorate the shelf as desired. If many coats of paint or stain has been applied, let the shelf dry overnight.

  7. 7

    Put the shelf in the corner where it will hang and decide where it will be installed. Move it up and down to find the ideal location. When found, trace a line along the shelf edge on the wall indicating the length of the shelf.

  8. 8

    Install two of the wall brackets on one wall of the corner. They should be installed just below the previous line by screwing some screws into the wall. Repeat this step with the remaining two brackets on the other wall of the corner. Four brackets should be sufficient for a large corner shelf, but add additional brackets for support if the shelf needs to hold heavy equipment.

  9. 9

    Lay the shelf on the brackets, so it rests comfortably there. Push it into the corner, so it is straight up against both walls. Secure the shelf to the brackets by putting screws into the shelf through the brackets from the bottom of the shelf. It may be required to get down on the knees to get a better view of the bottom of the shelf, if the shelf hangs low.
