Hints on Ishgard's future.

[Zetsumei_Tsunarashi]

I kind of feel like the reason they don't want to do a snowy housing area is because a lot of the outdoor furnishings and fixtures wouldn't look good in a snowy environment.

You would expect everything to be covered in snow but things like your roof, plants, gardens, and chocobo stable would be void of snow. Certain plants that you can place in your yard wouldn't conceivably be able to survive in colder climates so wouldn't make sense for them to be there. Your ponds which should be frozen would still be liquid. Things like leaf piles and stepping stones that should be burried under the snow would be on top of it.

Things just wouldn't look right and people would complain about it so that's why they probably won't do it.

That being said, there's still plenty of candidates for housing areas in heavensward zones other than coerthas. The Hinterlands or Sea of Clouds would be good choices imo.
