Your project looks great, we are all looking forward to seeing pictures of the progress and completion.
Just for basis of comparison, or why I am chiming in....My house in northwest NJ was built in 2003, but the basement was unfinished. Took me a few years to bankroll my way through the project (doing most of the work myself) and ended up with 1200 sq feet; Lost a lot of room to utilities and fireproof code requirements.
I tried TurboCad to assist with permits, but gave up quickly in favor of graph paper as I don't possess your talent! Everything looked gigantic and wide open until the drywall went up.
Original 3 pins grew into 16, and plan to squeeze in more. I struggle with keeping the foosball, skeeball and ping pong tables, but they are popular with the younger audiences during parties.
I will work on finding pictures (and wont highjack your thread!) to share at some point. Nothing went as smoothly or quickly as I had hoped.
Hoping your layouts above prove effective in getting that much "fun" into the project. That's a lot of electrical outlets to squeeze in there too!
