First off, I apologize for not seeing your question; totally my mistake. Yes, it is heated & air conditioned. I don't have easy access to the dimensions, but it is a full court, not much space around the edge, with an equipment room on one end and a small room & bar kitchen on the other end.

We are in Northern Utah, and would be happy to build for if you haven't already built. Once again, my apologies. ~Sherrie
