Working out of a home-based office is certainly not for everyone, so it's important to consider the many advantages & disadvantages before you make it a part of your work process.
If you're creating an at-home office to work from every day:
Let it fit with the rest of the home.
Get a professional phone number.
You may not want to reveal your private home address or phone number. This is where a virtual office can come in handy.
Good lighting is important.
Consider how YOU work best. Do you need complete silence to get anything done?
You may not have an entire room you can easily dedicate to an office or a study, but that shouldn't limit your ability to make your work space feel professional when necessary.
How much space do you need for storage/filing, etc.
What will you be doing in the space?
Will clients be visiting the space?
What type of equipment is required?
Check insurance coverage. Are you covered for business visitors or even delivery people?
If you're just creating a small at-home office nook consider adding a desk in your bedroom. A bedroom can be the perfect place to add a work area if no other options are available. It’s peaceful and away from distractions that you might have in the main living areas of your home.
If you have a guest room/den that's not occupied with guests that could also be a great place to create a stylish environment where you can do 'double duty'.
