Final Mezzanine

In my other post about adding a mezzanine, I concluded that I was not very happy with any of my tests and that I need to think about it more in order to create a mezzanine that is functional however is still aesthetically appeasing. Therefore I have played around on sketch-up a bit more and have come up with this design. I have added a few doors and a spiral staircase into the images in order to get a better sense of how the space will be inhibited and will function.
