What did the rich man wish for in the poor and the rich man in the grimm brothers tale

He finally said, "What else should I wish for but eternal happiness, and that we two, as long as we live, may be healthy and have every day our daily bread; for the third wish, I do not know what to have." The lord suggested that the man might want a new house. The poor man said that it would be nice to have that. The Lord left and the couple was soon surprised to see a brand new house where their old house once stood.
