I have a large "office built-in" cabniet in a corner of my bedroom. You open the cabniet doors and you'd see a top table for printer, and underneath that is for my computer. Lots of shelves. On bottom of the cabniet I have a filing drawer and a pull out table to write on.
It's so nice to have, you can just close the doors and hide your mess
But the problem is - I don't like to be "cornered" so I always work in my living room where there's plenty of openess, air, light and warmth coming from my large windows.
All paperwork I have are basically on the computer.
