It's really good if the character home regulation is to preserve the character. Unfortunately it's just an excuse to bring down the size of the house. Look at the regulation, if you tear it down and build smaller house, you are exempted from character home regulation. You can actually ask people to build a new house with current regulation's size with character home's shape. Unfortunately it's not about the shape (character) but the size. This is LAW UNCERTAINTY. Next they will come out with character neighbourhood, then character city, etc.
