Homeowners often install a corner cabinet in a kitchen to increase storage space. These cabinets can either have a door or be open to display pictures, crafts, or other items. Often, revolving trays, known as Lazy Susans, will enhance the functionality of the corner cabinet. Building a corner cabinet may seem intimidating, but you can do it yourself with simple power tools.
Measure the space in your kitchen and determine the size of the corner cabinet using a tape measure. Allow enough room for other items in the kitchen, but make the cabinet large enough to store items. Determine how much material will be needed using a sheet of graph paper. Draw the sheet size to scale on the graph paper. Draw each part to scale on the same sheet, this will allow you to calculate how much material you need.
Mark the melamine sheet where the parts need to be cut out, using a pencil and a straightedge. Cut the melamine with a circular saw on each line. A typical corner cabinet will be 82.5 cm (33 inches) wide out each corner, 60 cm (24 inches) deep, and 86.25 cm (34 1/2 inches) tall. You should have two cabinet side pieces that measure 60 cm (24 wide) and 86.25 cm (34 1/2 inches) tall. Cut your top and bottom 78.75 cm (31 1/2 inches) tall and 78.75 cm (31 1/2 inches) wide. The two backs should be cut 82.5 cm (33 inches) wide by 86.25 cm (34 1/2 inches) tall. Confirm that each part is square using a framing square.
Cut the top and bottom on a diagonal by measuring up to 60 cm (24 inches) on each side with a tape measure. Mark a line from each mark with a pencil. You will be cutting off a 22.5 cm (9 inch) triangular piece of melamine on both the top and bottom parts. Cut the material using a circular saw.
Measure the diagonal section on the top and bottom. This will be the width of your cabinet front. On a typical 82.5 cm (33 inches) corner cabinet, the front will be 27.1 cm (10 7/8 inches) wide by 76.2 cm (30 1/2 inch) tall. Cut the front out using a circular saw.
Label the parts on the 1.8 cm (3/4 inch) edge of each piece using a pencil to avoid confusion during assembly.
Drill four 3 mm (1/8 inch) pilot holes in the top and bottom on the cabinet sides. The top and bottom sections will butt into the sides. Apply a thin layer of glue to the sides at the joints. Lift the side into position. Screw the two pieces together using 3.7 cm (1 1/2 inch) grabber screws.
Attach the back by applying a thin line of glue along the joints. Screw the back onto the cabinet using 3.7 cm (1 1/2 inch) grabber screws.
Allow the cabinet to fully dry before handling.
Purchase two hinges to attach the door to the cabinet. Screw the hinges onto the door using a power drill and the screws provided with the hinges. Hold the door onto the corner kitchen cabinet and tighten the hinge screws, using a power drill.
Paint the cabinet using a melamine paint. Melamine paint is thicker than a traditional paint and found at any DIY centre.
