Cool places to live?

IGLOOS

Frosty homes built from blocks of snow might keep Arctic residents cozy inside.

This clue plays on the double meaning of "cool." While it could describe trendy or fashionable places, it’s hinting at somewhere literally cold—like the icy homes built from snow blocks. "Igloos" fit perfectly as traditional shelters in Arctic regions, making them both "cool" in temperature and cleverly tied to the clue’s wording. The answer relies on that simple pun to guide solvers.
