My office is a mish-mash of junk. 2 Ikea secretary desks. 2 Ikea bookshelves. 2 Industrial office desks. The only salvagable part is the Container Store Elf shelving wall hanging printer center.
I love this solution and think I can build it, when I'm healed at least. Oh, and after I build Lizzie's bed!
You can build the entire room!
Go for the build. You will be much happier and you can use ALL functional space!
