This is my kitchen island, below is an unfinished utility/storage room. A hydraulic scissor lift is at bolted to the cement, and then a small frame is built on top of the scissor lift table. On top of that is a subfloor, flooring, and then the island. The cabinet doors are on the other side, and have safety push button switches that kill the electricity from the Smart Home Insteon switches, and prevent it from moving when the doors are not fully closed. This lift can easily lift over 1,500lbs, so it was an important safety feature! Please comment if you are interested in seeing the inner workings of this.
Believe it or not. I used IKEA boxes and hardware with custom walnut fronts built by Scherrs. They are the best: http://www.scherrs.com/
