I think that is really neat. I doubt I would ever want to park a car on / in the carport. One could probably have wind power and solar power as the sources electricity. It would be nice to see it when it is actually built, so one can compare the design with the reality.

Cliffs are a dynamic environnement. Building near a cliff is dangerous as their is a risk of falling over with the cliff, especially aftyer tempest or heavy rains. So building over the cliff would be a major risk.

Cliffs are cliffs because what was there before broke off. (What Deres said)

This is perfect for any post zombie apocalypse survivors.

This sort of house design could also be nice for a lot of vertically oriented properties that are far from the ocean. If they do hang over the ocean, the house will need some sort of grey water and sewage pumping or treatment system built in to the bottom level.

Inspired by barnacles? This is basically Tony Stark's house as introduced in the comics back in 1987.

It looks like the cliffs are sandstone, from the description probably somewhere in the Great Australian Bight.
You'd want really DEEP rock anchors holding the house up in that situation.

This construction is undoubtedly very cool but I do wonder how permanent a home built in this type of location would be. Pieces break away and fall from cliffs that's how cliff's came into being and I'm not sure that I would like to pay for a home that has a short life expectancy, nor would I like to be in it when it decided to let go.

Architects and their juvenile fantasies.

Definitely over the edge ;-)
