Building plans.

I have recently gotten somewhat sucked into architecture (as you can see on my recent projects) and I've been trying to think of what to build next. My ideas are:nn1. Full size aircraft carrier (might make a mini version first, just so I know about what size I need to make it.)nn2. Single player airport (just a hanger and a runway, might add some special stuff upon request)nn3. Try making a better warship or updating the current one.nn4. Some stuff that could help out beginners.nn5. A series of tree houses ( I already have a few schematics I have made, might post them eventually)nnPlease comment on what you guys think or perhaps some suggestions!
