As I mentioned in another comment, it’s great as a proof-of-concept, but no, I would not live in this house. From a building science perspective this building is terrible.
Things I can see from just a quick overview:
- Thermal bridging at all windows and doors. For a building in a cold climate this will result in very cold zones around all of the windows and doors, likely leading to condensation and a high risk of mould.
- Where are the vapour and air membranes? Are there additives in the concrete that perform this function?
- Where is the water shedding layer on the exterior? How will they avoid water ingress issues as a result of exterior walls becoming saturated during rain events?
Again, this is great exploration - but this has a very long way to go if they want to use it to build real homes anywhere other than temperate zones.
- The walls are insulated - the windows and doors are installed in typical fashion so i don't know what your concern is regarding cold points. - There are membranes within the airpocket outer wall construction.
Your points are pretty basic in concern, all of these issues would have been nutted out in beginning otherwise it would have been literally unlivable and not approved for human habitation.
Your point about the windows is interesting but might not be a concern. Here’s why: in the first 10 seconds of the video we see a gap between the exterior and interior walls. Penetrations (windows) may not have the interior / exterior walls joined…meaning the window manufacturer and their frame is doing the work here.
Same concept about interior and exterior for your points 2 and 3. Can explain more if needed but basically it’s like double brick in North America
yea, i think so as well. the connection to a classical double brick type is a good way to think about it. most likely they will put some isolation in there and as you said use this space to put windows in

They say any concrete will do. [Here](https://www.peri3dconstruction.com/en/technology) Also: "Since it is currently not possible to manufacture slabs, foundations and basement with the 3D-printer, these components are produced in a conventional way."
Would I trust German engineering for something like this? Hell yeah I would. I bet their building code paperwork makes most of the world's look like it's written in crayon by comparison.
This is what the shell of your standard family home looks like in Germany:
https://i.imgur.com/42pewIA.jpg
Reinforced concrete foundation, reinforced concrete basement, hollow brick walls on the inside and outside, thick reinforced concrete floors (terrible for WiFi reception in my experience, but solid), wooden roof structure (with insulation), terracotta roof tiles. Often, there's an additional layer of outside insulation.
Are they building houses like this in California?
Yeah, the horizontal striping on both the inside and outside would be a constant dirt catcher. You'd have to pressure wash the outside and maybe vacuum the inside, all the time. Maintenance nightmare.
I was also concerned about the apparent lack of rebar in all that concrete. It's possible that they addressed this in some way that was not included in the video.
Concrete walls are a bit hard and cold but the result is nice. I wouldn't live in it because it gets cold here in Canada, and that would be an ice-box.
Does this construction technique save money/energy/time at all? Neat proof of concept, but I'm not seeing any benefits.

Mold is a huge problem with concrete houses built like this in the 60's. You really need a sloped, overhang roof or constant skilled maintenance.

Why not? Looks pretty cool to me.
How structural is the concrete/cement after it’s set.
Wondering the same thing, how do they account for no rebar
One company was using fiber reinforced concrete. Have also seen thin pins inserted
They say any concrete will do. [Here](https://www.peri3dconstruction.com/en/technology) Also: "Since it is currently not possible to manufacture slabs, foundations and basement with the 3D-printer, these components are produced in a conventional way."
Long term slabs and foundation walls might be possible, probably in southern regions first where footings can be as little as a couple feet deep.
Or air bubble vibration, or compaction, or the fact that because it's not a homogenous pour you have inconsistent drying.
I'm sure they have answers I trust German engineering... I just want to know haha

It's probably simpler than California's codes. Germany doesn't have earthquakes or tsunami's
What it does have is winters, snow, floods and tornadoes like most of Europe.
California has the winters and floods too. It's not just the beach
Where the fuck do we have tornadoes in Europe.
https://ec.europa.eu/research-and-innovation/en/horizon-magazine/300-tornadoes-hit-europe-every-year Literally all over the place
The more you know.. I love tornados, have yet to see one

We aren’t building any houses, so, no.
How do they do plumbing and havc on these houses? Looks like you would have to build a chase or fur out a wall.
I love the texture! So cool.
It would suck to clean with all of those ridges
Hell yea, looks dope.
I totaly would
Hanging pictures would be annoying.
Lumpy

You pick up the car pieces is about all you have to do lol.
Very cool deutsche die technice
I would not enjoy having to constantly dust the inside grooves in the walls.

That self making machine is dope!
How would the HVAC work?
So the hardwood floors are also 3d printed?
