Bill's house is first seen in Chapter 9.
While here, Bill tries to fix one of his inventions and accidentally is transformed into a Rattata. Later, after Red saves him, Bill takes Red to his house to formally introduce himself and show Red some of his work.
Bill has numerous inventions here, including a Pokémon teleportation device that causes him to merge with a Rattata.
