A lot of the UK houses are quite old and so they used the materials that were common at the time. My house is a mid-terrace house built around 1895 for mining workers, so it was built as cheaply as possible and doesn't seem to have a proper 90-degree angle anywhere.
It's going to become a much bigger problem in the UK as we're struggling with having enough housing anyway and making them energy efficient is going to take a lot of money and work.
