Perfect Grow Room

So i see lots of suggestions and grow rooms from everyone. I was just curious if any of the pro's had a sketch or could explain what a perfect grow room(s) should consist of and look like. Im sure theres gotta be a top-of-the-line way to do it n im sure someone knows it or even has it. Maybe im asking for a dream room even idk. I understand from what everyone says what u need and such, but room sizes are always way different. So anyone care to elaborate?

you first have to decide how big of a crop you want to decide how much room you need.and how much electricity you want to use
