The basic kid’s desk was designed by Marc Spagnuolo, a.k.a. The Wood Whisperer and is copyrighted by him. A video showing its construction can be found at the link via YouTube. The desk is 24×16 inches on the surface and is 24 inches high. We designed a chair to go along with the desks which, due to the extra complexity in making it, some may choose not to build. We did this because, at least here in Santa Fe, NM, finding a kid-sized chair in any local store was impossible when we went looking.
The idea behind the desk and the chair is that they are extremely inexpensive and easy to build. The kid-size desk/chair combo costs about $45 in lumber. Expect to spend around $30 if you are just building the desk.
