How is the family's dream house different from their real house on Mango Street?

The dream house would be theirs permanently, and would boast running water, working pipes, real stairs "like the houses on T.V.", a basement and enough washrooms to accommodate the large family. The yard was also worthy of Papa's lottery ticket and Mama's bedtime stories: the traditional white exterior and a big, unfenced yard with trees. What the narrator sees is contrary to everything her parents said; her house is tiny, crumbling, and without a yard.
