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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
