This was last winter's project for me. When my wife and I got married, we both had large collections of wine. We each had "free standing" wine refrigerators in our homes. When we moved in together, there really wasn't room for both of them, so I kept mine at my other house in a nearby town and my wifes was in our house. Our collection grew quickly, and we soon ran out of room. We decided rather quickly to build a wine cellar in our basement to house ALL the wine in one place. Our basement had a dirt floor with decking over the top. We excavated dirt to make the floor level, added 4-6" of drain rock, and poured a slab over the top. Once the concrete was in, I started building the room. Here are some picture of the framing work, including the 6 mil vapor barrier. I moved that junction box from the center of the room... I started this room on March 1st last winter and finished on May 7th. One of the fastest projects of this magnitude that I've ever done.
