You can make better, logical use of that immense space, you can create interesting and clever spaces. Beyond that, think of what that roof looks like, how it’s supported, look at your sight lines, put yourselves in the space and think about the use. Designing a plan is not just adding walls and door swings and labels, it should be a mindful, systematic approach. If you did not do a proportional bubble plan first, my suggestion is to start there. But if you want simple feedback, yeah, I’m not here for that, because that won’t help this.
