Eight feet is really pretty high unless your next door neighbor is two story. The bamboo sounds like it would need varnishing/sealing too much to be real practical.
I have acid stained floors in my showroom and my home. I don't mind them at the showroom as it is easy to clean and I always have shoes on.
I thought I would like them in my home, but alas I do not. They are too cold for bare feet and so we ended up with area rugs everywhere. Fortunate for me, I'm in a long term rental and so will be able to change my floors this fall.
Should you decide to go with the stained concrete, let your builder know upfront as you need to take special care not to leave any marks on the floor from things like grease that will embed in the concrete and comes back through the stain. Feel free to come by my showroom and I'll show you what I mean. The stain folks did their best to hide the marks, but they remain visible.
