11. Take Advantage of Vertical Space
The space you use is probably limited if you are working in a small office at home or a bedroom. Most people don't have the luxurious room as their home office. Bookshelves, filing cabinets, and a second desk may not be an option. However, lots of people have free space on the wall. Take a look around your room and wonder if something could be on the wall instead.
Consider installing floating shelves above your desk to store books, plants, and other objects that will take up too much space. If you're particularly comfortable with construction, you might even consider installing top cabinets for storage. This gives you lots of additional room, and it makes the most of your vertical space.
