Scooby was posting about this a couple of years ago on Dominams.com. It must be getting trendy because my girlfriend and I will be building ours out soon. We bought a farmhouse in the country of Kentucky with a nice pole barn on it. The previous owner was big into restoring old cars and put it under heat and air with insulation. Our plans are to use it for private parties when our friends come in from Chicago. That will be a four hour drive for them. They would come to see us anyway but we want this to be a nice party spot because I don't think we are going to find anything close to an active fetish scene where we are. My question to you is what is important to you in a play space? We have a generous amount of space and tall ceilings to work with.
