We also need houses to live in .Also people enjoy living in a house. Living in houses can be hard because you have to clean up alot.
Another reason we have houses is that builders need jobs and money.The way they do that is by building houses. Sometimes it's challenging to build certain houses like concrete bases and wood bases. Builders have hard times sometimes but they have an important job.
That is why people build houses.
