The longer the driveway, the grander the house.

Stephen Resnick, a real estate agent at Hilton & Hyland, said he's seen an increase in demand from wealthy buyers looking for elaborate driveways leading up to a home. "It makes a statement that you are being led up to a magnificent estate."

This driveway leads to a 30,000 square foot home selling for $39,995,000, with the main house featuring 10 bedrooms, 22 bathrooms, two family rooms, a gaming room and a professional screening room.
