Here you go, real progress pics taken several days ago
Second floor shot (taken freehand at 430 pm to illustrate light availability)
The cliff section is far from done but has taken a good shape to give an idea of the rough layout. First the team measure the working ground and dug as neccesary. Bottom plumbing was installed before they poured in concrete for fondation. Thick steel wires were shaped and laid as base shape forming skeleton along with guideline/basic brick works. Work progress from bottom up with earth/sand fillings by the empty inside.
Spots where water will drip from are reinforced for extra strength and water resistance (the grayish unfinished spots) and the outer skin is carved on (a process that reuires uncommon artistic hand). As you can notice there are several (I think 5 of them) whitish pipe appearing out of the cliff part. Those are spots where water will gush out and drip down to the pond. The debit of water of each outlet will be controlled remotely by valves to achieve maximum effect. The sticking pipe pole by the center is just there to cover pond drain from getting covered by debris (there is a draining hole at the bottom of the pond).
If you can see the woven steel which is surrounding the bottom and sides of the pond which will be sealed with 19mm glass.
(I'm verry sorry for no step by step pics for those of you who would like to see because I'm busy and the team works so fast that what you see here is done in only 5 days).
Here is a pic showing detail on how the realistic and natural texture of the cliff
It is porous just like those of real volcanic cliffs. Pockets are there for non water plants to fill in.
