Ideas for a U shaped corner plan

Is it an inside corner? Or outside corner? A little sketch of the space/room/obstructions/access/etc is always a good starting point.

Here's what I think is the space you have, 12' on one leg, 16' on the other. The ovals are O-36 and O-48 to give you an idea of the space.

I like that. Hoping to add 1 or 2 inside loops. I have up to O72 curves. Right now it’s similar, but sold the layout short with incline/declines, a bridge, and lack of access .  Hoping to do the “U”
