Terraced houses are houses that are all connected together in a row, just like a long train of houses. Each house in the row is usually the same size and shape as the ones next to it.
Think of it like a bunch of toy blocks that are lined up next to each other. Each block is the same size and shape, and they're all connected. But instead of blocks, they're houses!
Terraced houses are popular in some cities because they allow a lot of people to live close together in a small space. This can be good for the environment because people don't have to drive as much, and it can also be convenient because you can be close to your friends and neighbors.
One thing to keep in mind is that because the houses are connected, you might hear your neighbors' music or smell their cooking. But if you like being close to people and don't mind sharing a wall or two, a terraced house might be a great option for you!
