Just my two cents here, but I really don't need player housing in ESO. There are plenty of other things ZOS could invest their time and money into other than yet another potential crown store money grab. There are plenty of bugs that STILL need to be worked out that would mean a whole lot more to me than another collectible luxury item. Any way, sorry for the rant.
I have checked the public guild vendors. No such stuff were up for sale. I guess I'll have to make an agreement with some crafter.
I don't know if it's been said, but crafting glyphs and brewing potions is fairly essential and can be profitable. Provisioning perhaps less so, since food / drink are readily bought and last such a looong time. Of course, someone has to make them too.
In regard to armor sets, I believe Twice Born Star is still among the best for trials, whereas for PvP I haven't worn a crafted set in a long time. The ability to craft any style and any trait occasionally leads me back to crafting, if only the art design didn't suck so much. There are only a few styles that truly appeal to me.
