There is a dome that is of the monolithic airform-rebar-shotcrete type located in Fern Acres about one to two miles down Hibiscus St. It is on the right side of the street and visible from the street. This house appears to be about 30-40 feet in diameter. While searching the net about this type of construction I discovered another similar method described here:

Whats interesting about the flyingconcrete website is that they use lightweight concrete with pumice as an aggregate. On this island we have an abundance of volcanic cinder which has qualities similar to pumice.
I would think this type of construction would be well suited to higher elevations with dry sunny weather. Supposedly it has both thermal mass and insulating properties. The outer roof layer is pure cement, but I'm not sure how well it would hold up to rain here as I've heard the cement here is porous.
Would love to here your thoughts on the subject.
