I don't know why the series makes me so happy, it just does. I'm never going to live in a tiny house, not even if I live by myself, but I really like the way that they pack so much functionality into a tiny house. It's like the building equivalent of a Swiss army knife.
I've never seen it but I do watch George Clarke's Amazing Spaces. I'm the same as you, I am deeply fascinated by tiny homes. My very first property was a studio flat so I watch these things and lament all the things I could have had in it, but would never actually have been able to build
One of them is a lovely story about a woman moving back to Mississippi 10 years after her house was destroyed by Hurricane Katrina and building her new tiny house on the plot of the old house. It turned out gorgeous but I did think at the time I was watching it that it was a mistake to put her teenage son's bedroom in an open loft space over the living area, and sure enough in the several-months-later section the whole family mentioned noise and privacy issues.
