Corner benches are an exellent use of otherwise useless corner space, on your porch, deck patio or inside your home. A floating, wall-mounted, corner bench provides a permanent seating area for reading, or for just sitting and taking shoes off. A corner bench gives storage underneath or items like shoes, gardening supplies or stacks of books. Building a corner bench inside or outside your home takes less than a day to complete.

  1. 1

    Cut the wood pieces to create the frame for the floating corner bench. You need two pieces measuring 32 inches long and one piece 45¼ inches long. Mark with a pencil and cut with a mitre saw. Once cut, set the mitre saw to cut 45-degree angles and cut angles into the ends of all three pieces. Make sure you set the angles facing in opposite directions on each board.

  2. 2

    Measure 15 inches from the floor and use a level and chalk line to produce a straight and level line that extends three feet from the corner. Make two chalk lines, one for each wall that meets in the corner.

  3. 3

    Set the first 32-inch piece into place, aligning the top of the board with the chalk line. Have an assistant hold the board into place and use a stud finder to locate the wall studs. Once you locate the studs, drive a four inch wood screw through the 32-inch piece and into the wall studs.

  4. 4

    Set the next 32 -inch piece into place on the adjacent wall. Set the end of this 32-inch piece against the end of the other 32-inch piece, to create a 90-degree angle. Have an assistant hold the board again as you locate and screw through the piece and into the wall studs.

  5. 5

    Set the final board into place as the hypotenuse of this right triangle. The ends of this board should extend past the ends of the 32-inch boards and set flush against the wall. Drive screws through this final board and into the angled ends of the 32-inch boards. Use two or three screws at each junction between these boards.

  6. 6

    Cut the OSB board for the bench top. Use the mitre saw, tape measure and a carpenter’s square to cut a section of OSB board into a right triangle measuring 32 inches on both legs and 45¼ inches along the hypotenuse.

  7. 7

    Set the OSB triangle into place over the frame. Secure the triangle bench top into place using two inch wood nails and a hammer. Leave approximately six inches between each nail head.

  8. 8

    Sand the rough spots and sharp edges of the OSB bench top and exposed parts of the bench frame. Remove the sanding dust with a tack cloth and paint or stain the bench as desired.

  9. 9

    Allow the paint or stain to dry and then apply more coats of paint or stain as necessary or apply a coat of polyurethane to protect the wood from water damage.
