Its an Earthbag construction dome, with a cloverleaf floor plan. All told its about 400sq ft, but the single structure can be duplicated and combined to create much larger structures.

Here's a quick video regarding Earthbags and the Eco-dome in general:
And here's a tour of an Eco-dome in Jordan:
The Eco-dome is a good plan, but in my opinion, the bedroom side domes are too small, at least for someone well over 6 feet tall as I am.
That's a fair point.
We plan to take the basic concept and enlarge it. The central dome in Khalilli's Eco-dome has a 15 foot diameter. In "Earthbag Building" By Kaki Hunter and Donald Kiffmeyer, its stated that the largest corbelled dome should not be more then 20 feet diameter. So we plan on making the Central dome in our eco-dome with a 20 ft diameter, and increasing all outer domes in proportion.
Watch the "Jordan" video I linked to above and you can see a clever way to use the bedroom niches. In that video, it appears they had a custom mattress made, that conforms to the entire area of the bedroom niche, and storage is available under the mattress. She sits in the bedroom, which gives you a decent idea of its size, (it appears large enough to sleep someone over 6ft tall comfortably) she also implies that she and her kids sleep there, implying that its fairly spacious.
Just this weekend I took some marking paint and a chain, and drew the floor plan out on the ground in my back yard, just to get an idea of scale. My concern was less with the bedroom niches, and more with the kitchen niche. In that same video, I mentioned. we see those niches applied to a very sparse kitchen. While I believe I could be fine with the bedroom as is, I do not believe I (nor my wife) would be happy with such a tiny kitchen.
Unfortunately, I still found the proportionally-enlarged kitchen niche fell short of the size kitchen I would prefer. Needless to say, we're still on the fence on what to do about it. More chin-scratching required...
Why not make the side domes the same size as the central dome? Cal-Earth's plans are only suggestions, and every site is different with different needs. I don't know if you have seen it, but this is a terrific earthbag blog: earthbagbuilding.wordpress.com
No reason other then I like the cloverleaf look of the eco dome. In the end, that's probably what I'll do.
Yes, I've seen the blog, good stuff, and he has several plans that I like on his website.
i also found this guy in Brazil using mesh produce bags eliminating (like onions come in) the barbed wire....
I've taught half a dozen earthbag dome building workshops around the world through Earthen Hand Natural Building.
You can see the 23ft. earthbag dome I designed and built in Thailand back in 2004, and the 17 ft. dome I designed and built in Mali in 2009 at:
