Alley house

An alley house is like a little house that's built behind another house. It's called an alley house because it's usually built in an alley. This could happen when someone wants to get more space on their property or build a separate home for someone else in their family to live in.

Sometimes, these houses are also called carriage houses or granny flats. They can be really small, like a studio apartment, or big enough for a family to live in. Some of them are cute and cozy, while others are big and modern.

People have been building alley houses for a long time, and they've become popular in some cities as a way to provide more housing options. They can be rented out to people who need a place to live or used as a guest house.

Alley houses can be a good way to use space efficiently and provide more affordable housing options, but they can also cause problems if they're not built properly or don't meet safety standards. So, it's important to make sure they are built safely and follow all the rules before you decide to live in one or build one yourself.
