Plan from scratch for new basement studio

Hi, I'm looking for a plan for my studio that we are about to build in my basement. I basically have 20"7" (628cm) X 12'5" (380cm) available space to configure as I wish. My ceiling is 8' (244cm) high. Ideally, I would have a drum booth and a Vocal/Ac Gt/Amp booth. But maybe I'm dreaming here so I'm ready to record my drums elsewhere. Maybe just a Vocal/Ac Gt/Amp booth would be enough. Or maybe I should simply record everything in the main room? I'm open to that. It's true that when I record my own vocals, that's the most convenient way for me as I also have to operate the computer, but I would still prefer to have at least a booth. Anyway, I just want to optimize my space so I'm wondering what configuration should I go for? How many rooms? What shape? Here attached, you will find a plan of our basement. Thanks for your help Andre Favreau
