I love the idea of printed houses, and I love the appearance of these walls. I have to add, though, as a professional cleaner, even "smooth" drywall walls get quite dusty (most household dust is shed human skin cells). These printed walls, with their texture, are going to accumulate lots and lots of dust in time, and it may or may not be as easy as vacuuming to remove the dust. Anyway, not trying to sound critical, I just love everything about this technology, and I'd like to do it myself.

@@turboflush The US is a very large place and I have seen a very large variety of building materials and designs. One difference I see typically in the US is the higher use of wood framing which makes sense from a cost and climate perspective and it actually is really efficient and is a good way to lock up carbon in a renewable manner. The higher use of cheap gypsum/drywall is fine too because their homes are all air conditioned so mold is less of a concern. In my country we typically would avoid these materials due to humidity , earthquakes, and termite concerns. With regards to plaster/stucco , this is fine but you have to admit those grooves/gaps are quite large so I would personally not use this method of construction if you wanted to make the walls smooth due to the amount of added labor finishing these curved wallets.

I feel like the biggest upgrade people will want is a few smooth coats on the inside walls to prevent dust. Also what happens if a pipe bursts in the wall? Or a wire burns out? Do you gotta cut that whole wall out?

I think based on other videos I have seen about how these are built, they are able to access much of those components through the attic. In Texas builders often use PEX for plumbing which is apparently very easy to repair due to how it is designed and installed. PEX is also more energy effecient than copper. Wiring would not "burn" out since a breaker would blow before a wire could be damaged, at least in the extreme majority of the time. But either way it would be able to be accessed through the attic.

Concerning lavacrete, how well does it stand up with earthquakes and foundation settling? Does it resist cracks? If there are crack failures, would they be easier to fix by adding some lavacrete repair?

I’m currently staying in a 3D printed AirBNB unit built by Icon in Austin. Very interesting. The only limitation, I think, is that the lava crete construction is limited to a single story. The unit I’m staying has a second story, however, it appears to be conventional framing. The other consideration, I assume, is that the setup on the printer unit is far more efficient when building multiple homes rather than a single unit. I would certainly consider owning one of these homes.

Then, there are other elements like horizontal metal straps and u shaped to tie the structure. Within the lavacrete itself are probably fibers to prevent cracks. Slab movement and flatness over time... how, was that engineering challenge overcome? Are there piers in slab that align with the vertical wall columns. (English slab method?)

English slab method: drill, install rebar cage, pour concrete. This forms a pier, engineered location for load bearing. Slab is then poured and structurally tied to the columns/piers.

Love to see this with SIP roof panels.

For owner repairability, incorporate plumbing and electrical chases into the design. When a pipe bursts or wire burns out - that chase allows a non-destructive access to the components. Think about cars for a sec. When we need to change the oil, we don't have to sawzall a hole in the body to get access. The designers thought about access ahead of time and made it integral to the ownership experience.

@Aidenjh11

The chase could be in the floor system, with small stubs for electrical panels in a wainscotting. Plumbing stubs come up into cabinetry directly. Keep plumbing and wires out of the wall completely. Separate the functions. The floor access could be made very generous and make it easier to work on or change out utilities than is the case with typical construction.

Just look at 22:16 to see the support infrastructure required to make this 3D printed house get started. Power requirements. Machinery.

Agree! It’s definitely going to play a part of the future of our housing industry.

not only does it look like corduroy, but with the patterns of the walls. it makes the walls look longer and the rooms wider, similar to how a pinstripe suit makes people look taller

Someone mentioned the echo in the house, this is easily resolved by using a cork spray coating on the walls. The corded nature of the walls already acts as a light and sound diffuser, adding a cork coating would enhance that significantly. As to dust collection, most dust sits in the air for a good deal of time before dropping to the walls or floor, good ventilation and filtering that keeps the air moving will lessen it's collection significantly. What I would really like to know about is how do these homes stand up in earthquake areas, we live in an area that has lots of small tremors almost weekly, how well do these constructions stand up under continual vibration??

I am just wondering about the cracking on the 3d printed concrete walls. is there any engineering on what's the capacity of the walls (compressive strength)?

Love this innovation for home builders! Love the look and I also love the thought as you want to change the interior you could plaster over the texture and get a different look.

We got in just at the right time. We signed just before Covid. People who came after us had a lot less choices in appliances and interior materials because Lennar couldn't get stuff. We picked a cheapie faucet for the laundry room and they ran out so they upgraded to the same one we had in the kitchen. We only ordered blinds for bedrooms they ended up doing the entire home no extra charge. Many of our neighbors came from a slightly older Lennar community basically across the street. So that told me a lot of people were very happy with Lennar. The only issue I had was after a year we had a roof leak in a valley. The roofers screwed up. Lennar plain as day gives you a year warranty. That was the only out of pocket expense. I built a custom home prior and I was the owner/builder. I had several roof leaks that were a lot worse.

So, now the lines go around the outside margins of the house in the ground. Quite honestly, plumbing change must be considered no matter what. Maybe drop-in cavities for updates.

Y'all brushed off the dust issue, pun intended. Cob webs and dust is a natural thing all over the earth. It's hard to clean off rough surfaces, so just be honest about it.

It's probably still a no-go for most residential construction projects, but being able to build round houses will be a massive benefit in the future. The reduced surface area of round houses massively reduces heatloss or gain. And with some clever computer simulations you might even find a shape, that's much better in strong wind areas.

It’s just too early for the dust (that 100% is accumulating) to become a complaint-level issue. I wince when the argument is “no complaints yet!” Especially when there is a very clear, experience based reason for concern. It will require a brush vacuum as noted, over every inch to prevent gradual buildup to a hard-to-clean level. The 5-year cycle mentioned sounds about right, but it’s a lot of work. And the walls in/near the kitchen will need that more frequently (maybe annually) because that dust is mixed with atomized grease and if left for long, becomes impossible to vacuum off and just attracts additional dust. With the texture of that wall, I shudder to imagine cleaning with 409-type cleaners that are needed for kitchen grease. I’ll put a steak dinner that dirt on those walls is a customer complaint inside 10 years, I’d like to see some proactive thinking into the issue.

My issue is the large rounded corners and seeing the layers. Furniture is square not rounded 8" corners. I still like the build. Would just need some alterations for me to like it.

Remodeled/restored a 1906 and three 1934 houses. They can be updated yet keep the original aesthetics. Now in some ways, the 1970s buildings hit bottom. Popcorn 8 foot ceilings, asbestos in several applications, hollow core doors, sometimes dreadful aluminum wiring.

love to see this sheer right off the foundation

I like how the StArchitect B.I.G. was barely mentioned and not even in the description. I am curious how much they were involved.

I have a plaster house but the floors are wood. That, I think, plus drapes and furniture absorb sound to some extent, but the rooms are kinda "live". Plaster's thick and heavy though, so the house acoustically isolates rooms better than about any drywall house I've ever been in does. I can hear the echo in that house even on the video -- sounds like a warehouse. What can be done to control that? Rugs, drapes, furniture? Maybe design room dimensions to avoid nodes? Could there be a sort of PumiceCrete that finishes like plaster but absorbs acoustic energy?

Super interesting concept. Couple questions. 1:) How is the air/vapour barrier connected at the wall/truss junction? 2:) I noticed a double bay garage, what is used for headers? Steel?

I don't know offhand, but I remember them looking at the garage in the first video Matt did. They may have covered that previously.

This looks amazing and I really am excited for this to become more mainstream. Question though, whats the RF resistance look like? Seems like wifi is going to be rough to get into all the nooks in this house...feel like a mesh would be required. But what about cell signal too? Metal roof and "lava-crete" makes me think signal is going to have a hard time coming in.

ICF's are a better building system that has been around since the 1960s and still hasn't hit the mainstream. Concrete, in any form, is a superior building material for many reasons versus traditional stick-built homes. With that said, I do not believe 3D-printed homes will ever become mainstream.

These are quite incredible. How are they attaching roof to walls? I lived in Houston and after Hurricane Ike there were full roofs literally in the trees. I’m surprised they are using wood trusses. Steel trusses would really add “bomb proof” vibes

I believe they said that they are tying metal studs all the way from the floors through the walls up into the roof... so the entire structure is tied together. With a metal roof done correctly, they are probably looking at 100 year life expectancy with a 50year or more warranty.

Questions: How brittle is the concrete surface? Can photo frames be hung using standard nail and hook hangers? If not, what is recommended?

How would you trim out tile or wood floors against the walls?

This is impressive. I have a question about this technique and technology. I live an hour north of this neighborhood (Fort Hood Texas area) and given that Central Texas as well as much of Texas is prone to foundation shifting and issues leading to damaged windows, doors and walls. How durable are these exterior and interior walls to cracking if or when foundation issues occur?
