Thinking about building a new home?

[Ultradog MN]

Or barn, shop, outhouse or maybe even a silo?
Came across this video today.
Looks interesting.

Though radically game changing, There are unresolved issues.
Poor "wall to wall" reinforcement
layer to layer shear (due to no cross linking even if fiber is used)
Building in electronics, electrical, utility components
Inflexibility of design once fabricated
Concrete is (actually) a powerful emitter of CO2 during processing from raw materials
No aggregate in the mix beyond fine sand
Massive reduction in real jobs that pay well
very little research related to settlement of, expansion/contraction of soils
seismic stability
I think there is arguments to be made for Structural integrated panels SIP systems. Jim

Let others be the guinea pigs.

when i clicked on the title i thought this was gonna be about barndominum craze https://advancedhouseplans.com/collections/barndominiums

Looks very interesting, but I fear Jim brings up several valid concerns.

Just spitballing here, but could you beat the layer shear by manually going around and driving some kind of steel pin/rebar in at intervals before the concrete sets?

once its mostly america ready- most developers will definitely have this kinda thing as viable options, remember these big pocketed big orgs are always looking for a way to reduce costs, generate income, and grow. you bet theres gonna be 3d-printed houses in the next 5-10years going mainstream.

jobs have come and gone since the beginning of time. if theres a way to make a buck from this, and make more bucks from this method you better believe they got their 'top men' their 'top men' figuring out the licensing/code deals as we breathe.

With out the stamp from a registered professional structural engine and architect I wouldn't live in it. Unless they are adding some type of rebar or reinforcement as the building is being printed I could see some serious issues with structural integrity particularly in seismic zones.

They are just starting out with this. I'll bet that through history there have been a few new things that came out that were later improved upon.

That's an interesting build method, looks like a concrete shell with foam insulation.

I've seen it used for barns and shops, but I wouldn't go that route for a house. The walls seem thin and there's not much room for traditional framing or utilities.

We built a more conventional 2x6 framed house with Grand Homes in Texas a couple years ago, 2,800 sq ft for around $520k including the lot.

They build with standard wood framing, good insulation, and proper sheathing. Felt more solid to us.

With no reinforcement I think that concrete will crush when the pictured roof structure is set on top of the walls. The last shot is definitely an AI fake.

There are quite a few YouTube videos on how these structures fail due to the concerns mentioned above, with equally fake Ai generated imagery.

So far would make an interesting garden shed, but some of the issues raised would keep me away currently for a ‘real’ structure.

But then im still struggling with particle board being used where plywood should go…..
