General Instructions

Work on a clean level surface and use proper safety precautions and equipment. Review the plans before beginning, having a clear understanding of how the plan will be put together. Predrill and countersink your screws, using glue. Check for square after each board is fastened.


Step 1

Measuring the tops. Measure the tops of your bases and make sure they will fit in a 15 1/2″ x 21″ opening. If they will not, adjust the trim lengths to fit in step 3.

Step 2

Tabletop Pieces. Cut out your tabletop pieces as shown above. For the corner, blue, cut a 38″ x 38″ square. Then mark on 2 sides 23 1/2″ from the back. Draw a 45 degree angle between the two points and cut off the corner.

Step 3

Trim Pieces. On the underside of the tabletop, fasten the trim pieces using the 1 1/4″ screws and glue.
Start with the red board, fastening it 3″ from the back edge and 1″ from the front side edge as shown above.
Then fasten the green boards, leaving a 16 1/2″ gap between the two green boards. Next, fasten the white boards. Where the white boards span the tabletop joint, make sure you fasten to both the corner and side tabletop pieces.
Then fasten the yellow trim piece in place. Finally, measure and cut the pink piece, mitering ends in 45 degrees. Use glue and let the glue dry with the piece laying flat.

Step 4

Leg. Build the leg by fastening 2 of the 1×3 boards together with glue, 1 1/4″ screws, and clamps. Let dry and fasten the remaining 1×3, again with glue and clamps and screws. Let dry. You can attach the leg to the tabletop by screwing through the top, screwing through the trim, or using corner brackets.

Finishing Instructions
Preparation Instructions
If you want to finish the plywood edges of the desktop, use edge banding ironed on. Sand the edges smooth.

Not only do I like this desk but I LOVE Whatever that is holding the inks and punches on the wall above. I have been going insane trying to find a way to put mine on the wall where they would be easily reached. Please tell me that is one of your designs and how do I make it.

Dear Ana,
Thank you so much for this website. I'm a police officer by profession, but I've always loved woodworking and carpentry. I've recently taken carpentry up as a hobby to pass time through a work related injury and have plans to build several of your designs . I can't thank you enough for the inspiration and the groundwork which will allow me to put my downtime to good use and stretching my money, while providing quality furniture that I will enjoy for years to come.

I would like to build the exact same corner desk as in the picture. Do you have the cut list and plans for the base units with the open shelves? Thanks.

Hi, I'm considering starting this project. I'm wondering whether the seams between the three different desktop pieces are visible. I'm assuming so based on other DIY projects I've done with similar aspects. Has anyone had luck hiding them? Perhaps by filling the whole length of the seam with wood filler?
