This is Twin Dunehouse at Atlantic Beach, by William Morgan Architects
I guess it's the Tropical Sister of the Bonderup house
maybe the slightly more popular tropical sister
because google seems to know more about it.
The Dune House by Architect William Morgan - Tansy Moon - More amazing video clips are a click away
Like the Bonderup vacation house, this house is again two big hollow eyes looking out from a sand dune. Whats confusing is that it's called Twin Dune houses, so I guess each eye is another person? or another house more like. Which just means that the tropical is sister is two one-eyed monsters.
