This is a desk that I designed and build a few years ago. I used the 3D modeling program SketchUp
to design the desk to fit perfectly into a free corner of my room. I incorporated an adjustable drawing board and two sliding draws. One for the keyboard and the other for pens, pencils, rulers and everything else. Using 3D modeling meant I could accurately transfer the design onto the wood.
It took me several months to create a design I was happy with, then the better part of a year to cut out the pieces then assemble it.
I had a very limited set of tools, and I only used a saw, a coping saw, a rasp, a screwdriver, and sandpaper. I also used an iron to put on the veneer edging.
I can't remember the exact cost, because I bought it all at different times, but it probably added up to a few hundred dollars.
If you would like me to make a more detailed instructable on how this was made please let me know in the comments.
