House built in a sand Dune

This $1.2 million home is built into a dune in Atlantic Beach, FL.

Turns out those smiley Lennon-style glasses on that glassy knoll are the legit windows of a legit house, and said house was carved into a dune in Atlantic Beach, Fla. Built in 1975, Dune House is the brainchild of architect William Morgan, who didn't want any interlopers messing with the character of his block — to this day, he lives next door. "I'm very particular about the buildings on either side of my own home." he says.
"The property is original oceanfront dunes that are very beautiful, and we were very interested in preserving the ecological character of our environment as closely as we could," adds Morgan. "So we surveyed the existing property and then we designed a house that would then be a profile of the original site."
