Step 1
Measure the space where you intend to install your kitchen cabinet using a measuring tape. Measure the length, depth and height of the the space to determine the dimensions of your cabinet. You may choose to build a single cabinet with the option of dividing it into multiple compartments, or you may build several individual cabinets.
Step 2
Cut two sheets of 1/2-inch MDF to the length and depth of your cabinet using a circular saw. These boards will become the top and bottom panels for your cabinet. Use the depth measurement and the height measurement of the cabinet, minus one inch, to cut two sheets of 1/2-inch MDF for the side panels.
Step 3
Stand the four boards you just cut upright on their longest narrow edges. Arrange the boards in a rectangular shape, sandwiching the side panels between the ends of the top and bottom panels. Drive 1-inch wood screws through the top and bottom panels into the side panels at 6-inch intervals to secure the frame.
Step 4
Cut a sheet of 1/2-inch MDF using the circular saw to the total length and height of your cabinet to serve as the back panel. Lay this board flat on top of the frame you just constructed, aligning the edges. Drive 1-inch wood screws through the back panel into the frame below at 6-inch intervals.
Step 5
Measure and mark the positions of your cabinet dividers along the top and bottom panels in pencil if you plan to divide your cabinet into multiple compartments. Cut the dividers out of 1/2-inch MDF using the same measurements you used to cut the side panels.
Step 6
Install the vertical dividers by sliding them between the top and bottom panels where you made the pencil marks. Drive 1-inch wood screws through the top, bottom and back panels at 6-inch intervals into the dividers to secure them.
Step 7
Cut your shelves out of 1/2-inch MDF using the depth and length measurements of your cabinet. If you divided your cabinet, you will need to use the length measurement for each individual compartment rather than the overall length of the cabinet.
Step 8
Mark the positions of your shelves along the side panels of the cabinet. Position your shelves horizontally between the side panels and attach them by driving 1-inch wood screws through the dividers, side panels and back panel into the shelves.
Step 9
Cut the door(s) for your cabinet out of 1/2-inch MDF using the circular saw. If your cabinet is a single compartment, use the dimensions of your back panel to cut your cabinet door. If you divided your cabinet, cut multiple doors using the length and height measurements of each individual compartment.
Step 10
Attach the doors to the cabinet using metal hinges. Install one side of two metal hinges along one edge of each door about 1 inch from both corners on one side. Screw the other side of the hinges into the cabinet frame.
Step 11
Paint your completed kitchen cabinet to match the decor in your kitchen using water- or oil-based paint. Allow the paint to dry completely before moving on.
Step 12
Mount your cabinet on the wall, if you choose, by driving 3-inch wood screws through the back panel into the wall studs. You may need to use a stud finder to locate the wall studs before installing your kitchen cabinet.
