Build a Diagonal Corner Kitchen Cabinet

A DIY Corner Base Cabinet for a Kitchen Remodel

When I was remodeling my kitchen, I built an L-shaped corner cabinet. There are some who like this style in their kitchen designs and some who prefer the diagonal corner style. I was asked if I had plans on the side for the D-style base kitchen cabinet and now I do! The DIY plans to build a Diagonal Corner Kitchen Cabinet feature two shelves inside with an optional Lazy Susan attached to each shelf. The DIY kitchen cabinet also features a face frame with a 1/2″ overlay on the door, which can be hinged on either side. This cabinet also features adjustable furniture legs and is another quick and easy kitchen storage build for a corner space!

Step One

Cut the pieces for the back of the corner kitchen cabinet. Note that one piece is cut 3/4″ shorter than the other so that both sides are equal from the corner to the end. With the pocket hole jig set for 3/4″ material, drill pocket holes in one end of the longer back piece and both ends of the shorter back piece as shown. Join the pieces using glue and 1-1/4″ pocket hole screws.

Cut the pieces for the sides. A 45° bevel will be cut in one side edge of each piece to allow for the face frame on the diagonal. Secure the sides to the back pieces using glue and 1-1/4″ pocket hole screws. the beveled edges will face each other.

Cut the pieces for the face frame and drill pocket holes in each end of the shorter pieces as well as one long edge of each 1×2 piece (not shown in the drawing). Assemble the face frame using glue and 1-1/4″ pocket hole screws.

Secure the face frame to the beveled edges of the sides using glue and 1″ pocket hole screws. Do not use pocket hole screws that are longer as they may poke out the sides! Brad nails can also be used through the bevels into the sides of the frame but they may poke out the back side of the frame.

Cut the circles for the Lazy Susan shelves. Install the Lazy Susan on the lower shelf first. Check out this post with detailed instructions on  installing Lazy Susan hardware.

Install the upper shelf. It may be easier to install of the pocket holes face up and the shelf is installed from the top of the cabinet (the pocket holes will not be visible). Install the second Lazy Susan.
