Breakfast Topics: What Building do you think Garrisons need?

I was just wondering about what I'd put in my Garrison if I could - I still think the idea of a Tony Start style armory where all your various transmog sets were on display would be cool, but then I really got to thinking about it - maybe an airstrip to allow you to fly between various points in Draenor (or perhaps that could be how we learn flying when it comes in, via the airstrip?) or perhaps a variety of race specific buildings could be added? Something like an elaborate orrery for blood elves, a crystalline tower for draenei, a clockwork robot lab for gnomes, a stump for orcs.

Honestly, I'm dead curious. What would you add if you could add anything?
