It's bad from the outside, but the inside is so much worse. And it gets worse the more you look at it. So many details that are just so awful. Living in this "house" is probably miserable.
The idea of shower controls on the outside is solid if you have a thermostatic shower valve, that way you can turn your shower on & have it be at the right temp for you before you get in.
However in this instance it just adds to the bizzaro feel to the while thing
