Claim to Fame: It’s a disco-era house in a dune!

About: This design by architect William Morgan is ensconced within the earth, forming two double-height apartments carved into a sand dune. The apartments are entered at street level and a common stair leads to the upper floor’s entryway, bedroom and bath. On the main lower floor, the living, dining and kitchen with mostly built-in furniture open oceanside to a covered terrace at beach level.

The building was constructed in 1975 using swimming pool technology, a gunite-concrete shell anchored to a cast concrete floor. It’s also one of the original green roofs, as it’s topped by a mantle of earth stabilized by native landscaping which helps to maintain a 70-degree temperature inside.
