Jay Gatsby's house represents his attempt to become the equal of Daisy Buchanan, a woman whose voice "is full of money." Gatsby's mansion resembles the Hotel de Ville of Paris with its salons and gilded rooms. In his house, Gatsby has gold fixtures, "Marie Antoinette music rooms, and Restoration salons." There are period rooms
swathed in lavender silk and vivid with new flowers, through dressing rooms and poolrooms, and bathroom with sunken baths....
After Gatsby has learned that Daisy married a man who offered her a $30,000.00 pearl necklace, in his "extraordinary gift of hope," he assumes that Daisy will again love him if he is rich and has all the accoutrements and furnishings of the wealthy. Thus, his mansion becomes what he hopes is a lure for her.
As he tours Daisy in Chapter Seven, he shows her his possessions, even pulling out his multitude of varied colored shirts in which she buries her face, crying "stormily," declaring,
"They're such beautiful shirts...It makes me sad because I've never seen such--such beautiful shirts."
Daisy reacts by burying her head in his shirts and crying. Clearly, Jay Gatsby has "an extraordinary gift of hope" that Daisy will divorce Tom and marry him because of his fantastic mansion and magnificent possessions. Moreover, as narrator, Nick comments that Gatsby re-evaluates everything through Daisy's reactions. Later, Nick describes this house as a "huge incoherent failure" since it has been built as a vision that has become corrupted. He has hoped to lure Daisy to him by ownins such a house, but his American Dream has left him bereft.
