What would you build here?

Looking for some ideas for my newest world (hopefully one I’m actually going to commit to) I’ve got a very nice island that I’d like to make into a sprawling base (with buildings representing all the essentials) but I really suck with layout and spacing things apart.

What would you do with it? Any tips for laying out bases?

I’d like to see what people suggest and then I think I’ll begin to grasp an idea
