Had the pleasure of living in a conex while deployed to Afghanistan. There was a company that sold them to the US Government for use as mini-rooms. They would take a 40 foot container and subdivide it into three private rooms. Each room had a twin bed, small desk, and a double locker to store clothing and other personal affects (even had a shelf at the end of the bed to hold a small TV and disc player). Each room was further equipped with very small separate bathroom (shower and toilet) and a sink/cabinet that was mounted in the room. Temperature of the room was controlled by a Mitsubishi air/heat unit. Wasn't the Ritz, but it served its purpose in the War Zone (not that we spent much time in our PODS - worked 12 - 16 hours daily). Again, it provided just a small sense of normalcy in an area where it was anything but normal.
Love the garage - good storage, space to work and cost, but living in community with an HOA, I know for a fact that I will never be able to have one.
