Who lives next door to the narrator Nick, Describe his house

Gatsby lives next door to Nick.

Gatsby's home is outrageous and gaudy, "a factual imitation of some Hotel de Ville in Normandy, with a tower on one side, spanking new under a thin beard of raw ivy, and a marble swimming pool, and more than forty acres of lawn and garden." The old-world imitation, the new ivy, the vast, wasteful enormity, all suggest Gatsby's inclination to be perceived as grand.
