This is the least desirable option for situating a home office, as it intrudes upon the rest of the family and may not be especially private or quiet. You also need to disrupt your office for meals—or vice versa.
Advantages: Convenient, minimal expense in setting up.
Disadvantages: Prone to disruption. Office needs to be packed up and moved during meals or when there are dinner guests.
Regardless of where you have set up your home office, be sure to draw up those boundaries we mentioned. Ensure that your office set up affords you the ability to work quietly, privately, and free of distraction when you need to.
