I have helped on about 500 earth built homes in Australia.
I developed the roof first idea when I realised the benefits of shade, rainfall collection etc.
Some people rage load bearing walls are better.
I have never claimed or suggested any design is better, but I think roof first in very convenient.
If you use steel poles, and even steel roof structure it goes up quickly, will not rot and if you install roof blankets immediately under the roof iron, it helps a lot in hot climates.
I have also built the Dalrac Mudbrick press that is similar to a Cinva ram, but with a wider brick.
In Australia there are also companies that can come and press bricks or make 'puddled' bricks on site for you.
Puddled bricks are called 'adobe' bricks elsewhere.
