Instead pining for the fancylad's kitsch hovel, how about asking why we can't have something that was cool, functional, and built less than 100 years ago?
They built it in 1929 in a grand example of Andalusian Regionalism, incorporating a shit-ton of ceramics. And it's beautiful in both the whole, abd the individual ceramic pieces.
And it's in use! There are government offices, a military museum and so on.
It's beautiful, I love it.
