Okay kiddo, so a housebarn is like a house and a barn combined into one big building.
Think of it like this: you know how you have different rooms in your house, like a bedroom, a living room, and a kitchen? Well, a housebarn has those rooms too, but it also has a big open space where animals like horses, cows, or sheep can live.
The space that the animals live in has things like hay for them to eat and a place for them to sleep. And the house part of the building is where people like the farmers who take care of the animals live.
So, in a housebarn, you have a place for people to live and a place for animals to live all in one big building. It's like having two buildings in one!
