Then there's the “type” of housing. According to PC Gamer's interview with Ion, they've developed lots of technologies to make housing work. In particular, he mentions the way delves get you into your own personal instance.
Based on this meagre information, I imagine that housing will work in the same way. He also said that there won't be just “Stormwind” for housing, implying that houses will be in town (outside we don't know) probably like ESO (there are houses in various locations and anyone can buy).
For customization, I don't think you can choose the architecture. If you want your own human home, go to Stormwind. If you want your wood elf hut, go to Bel'ameth. TBH I'd prefer it that way.
