They are as many work spaces as many different people and different occupations.
And different jobs need different tools, different space, different storage. But it is always about creating something; words, drawings, sketches, projects.
I am personally drawn to more colorful, eclectic work spaces, that inspire you even more while you in there. Being surrounded by different objects can be stimulating but sometimes a little overwhelming as well and some prefer it sober, white, simple.
What is your style? Do you fancy cluttered, eclectic work space or you feel more productive in a simpler environment?
