So while I was researching this project, I found this idea.
Now, my problem is we are on the water, and if I went down below the crawl level below to make the spiral staircase wine cellar functional, well, I'd probably also have to install a very high flow sump system to keep water out.
While the guys were installing the granite, I showed them pics, and the young guy said, well, instead of going down, how about making it come up?
Whoaa, I could do that! So, that's the next big thing. I'm going to design a system that has the mechanicals above the crawl floor, I'm going to knock out about a 1 foot deep depression, so I can build a unit that will extend up at least 5 feet above floor level in the kitchen at the push of a button. It will have bottom lighting and a glass door set up that is flush with the floor, unlike the poor execution of the below pics. I figure I'll be able to store about 400 bottles.
