I remember when geodesic dome houses were a fad for awhile. Those Monolithic houses have a bit of a Hobbit Hole vibe to them (I mean that as a compliment).
I used to want an earth home built into a hillside but with windows only on one side, you can’t see who’s sneaking up on it.
You know what doesn’t fit in a round house? Furniture.
Check this out. Round homes for places with hurricanes.

Not as substantial as the monolithic structures but they probably will not settle into the beach! (I think Sand will only support about 600 Lb/sq ft.)
I love those things too. Id probably go with an earth sheltered one like the folks at Formworks assist with. One of these days I hope to build...

Very easy to build and find, actually. They are all in disrepair though.
