For a basement, that size, the best way to get the layout that will suit your needs, is to do a 3D design of your basement.

This way you can make changes and move walls around and see exactly how it will look, as you're standing in the basement and doing a walkthrough.

If you are interested to do a 3D visual and explore different design options or have any questions I can help you with that.

Please leave me a message on my profile page and leave your email and I will provide you the details on how we can do this. Did this for many homeowners on Houzz and nationwide with great results.

Thanks and good luck.
