Sounds cool, please post pictures of your finished space, would love to see it!
And I'd like to point out something which I find very important, especially if you plan to give classes - don't forget that people have different heights and need different heights for working, too!
I am tiny, only 5 feet, and I took a course in February where they had the most inapropriate work space. The tables were too low to work standing, way too high to work sitting. The chairs they provided were not height adjustable, when sitting I couldn rest my feet on the floor but had to dangle them, nor did the chair itself had any kind of foot rest. After 3 hours my back hurt like hell from the constant unnatural position I had to take. There were 8 people in the class, and three of them were around my height and had the same problem. That really can take the joy out of a class, and makes you consider twice if you would book one again.
So my suggestion: either the tables or the chairs need to be adjustable. Best would be both, or offer different options for working space, such as tables, counters, or even trays to be rested on ones knees
