My Wife took a position where she will be working from home. I also work from home 3 days a week. We needed a nice office area, but didn't have the space. I saw an article on LifeHacker and decided this would be the best fit for adding an office space to our bedroom. I have just begun woodworking and have no experience. This was a fun project... made a few mistakes, but they are not noticeable. I am not fully complete (haven't attached the shelves to the desk yet) as I want to do some other room renovations before everything is all set.
Finishing: Grey stain and furniture wax to make it less "blue/grey". Then a couple coats of polyurethane in a spray can.
This is my first day working at the desk... the only thing I would change so far is maybe to lower the keyboard/monitor shelf by a couple of inches, but this completely depends on your size.
