It would be nice to automate this approach mind you, anyone thoughts on the realistic aspect of this current design ?

Speed, boyo, speed. The concrete sets as it is sprayed, so it doesn’t have to sit around in molds hardening.

As for the lament about blue-collar jobs, hand-made housing, etc., if you ever get stuck with the results of the very common practice of conning the building inspectors by doing some of what’s mandated for quality and safety, showing him, then ripping it out and carrying on cheapo-style afterwards, you’d have less nostalgia.

Here on the Wet Coast, many condominiums were almost rendered worthless by application of a central-continent building code, which mandated sealed walls and paid insufficient attention to exterior flashing design. The result has been a multi-decade “Leaky Condo” disaster, in which the vastly higher rainfall levels here worked their way into the walls — and stayed and rotted and grew mould. Extensive condensation trapped in the walls had the same result. One smart and ethical contractor I knew showed the inspectors the nice, sealed wall liners — and then slashed them with a box cutter before closing up the walls. Saved the houses, because it permitted air circulation and drying.

So fast, perfect, and EASILY REPLACED housing would be a fantastic blessing for many people.
