Fresh and Inspiring Home Offices

As some of you know, I work as a freelance web designer. Working for oneself definitely has it's perks, but with it comes a lot more responsibilities, as you are accountable for everything. I am always extremely busy, which I enjoy, but last week I was drowning, and spent most nights up until 3:30 AM to meet my deadlines.
Paramount to working from home is having a home office and work space that is extremely comfortable, functional, and aesthetically pleasing. Everyone has different work styles, and the furnishings and layout you choose will depend on that and the type of work you do.
