7. La Casa del Desierto, Spain
In the heart of Spain’s harsh Gorafe Desert stands La Casa del Desierto; a tiny glass house built to survive one of Europe’s most extreme climates. Fully off-grid and only 20m², it balances cutting-edge glass technology with pure isolation.
By day it endures 30º temperature swings, and by night it offers nothing but stars, silence, and serenity.
