Its seems like every episode of Grand Design does include an almost spiritual journey to a glue-lam pre-fabricated wood factory in Germany. I’m not sure that stuff is as easy to get over here. > how would you reuse it in a different project? The blocks are standard sizes so you can reuse them like legos.

> Its seems like every episode of Grand Design does include an almost spiritual journey to a glue-lam pre-fabricated wood factory in Germany. This is really weird to me because nobody builds like that here. Brick and concrete rule supreme and people living in wooden houses are seen as old hippies who cuddle with termites.

There's a misunderstanding here.

Glue-lams are not used for walls, they are used for floor support. While a lot of multi-unit concrete residential construction in Germany uses concrete for the floor without supports), for single family houses there it is still relatively common to span rooms with beams to create floor support.

This is also true for earthen buildings, which are remarkably popular (on a per-capita basis) in Germany. I say this as a US resident in New Mexico, where it is hard to imagine a place (Germany) less likely to use variants on the same best-practices as housing we build here.

If you live in California, you can potentially build one of these as an ADU (Accessory Dwelling Unit). Local agencies are required to approve an ADU within 60 days, and recent state bills (AB 976, 434, 1033, and 2221) make it easier to build/sell/rent ADUs on your property. You'll have to wait until 2025 before every locality is forced to have a process for pre-approved ADU plans (at which time you could potentially…

Surprisingly enough, Los Angeles is actually ahead of this timeline and rolled out a program more than a year ago to develop pre-approved ADU plans with private architecture firms. As of now, there are about 65 standardized plans that have been approved, ranging from ~300 ft^2 (28 m^2) to 1,200 ft^2 (110 m^2).

So their work is to check if it's conforms to state ADU law?

Plus things like site suitability, setback requirements, etc.

They are registered in England and Wales and they write about millimeters. I guess that they don't have 2x4 and 2x6 frames. Maybe houses there are built in a totally different way.

Yes, houses in England are not made from frames almost ever. They are made of solid brick. It was always so confusing to hear about Americans punching through walls. You can't do that here. There's no wood.

People talk about punching through /interior/ walls, which is typically drywall in the US.

The last time wikihouse showed up on HN (September '23) I did a deep dive on the process I still haven't come out of. 20 years ago as a grad student getting my masters in architecture, I definitely would have had similar comments to most of what's on this page. But I don't feel that way any more and I'm actually disappointed by the negativity toward this project – not because it's not warranted, but if this were a so…

That's really interesting about Github-based versioning. My company (bldrs.ai) makes a webapp that views IFC (soon STEP) and has github integration, so any *.ifc path on GH can be pasted into our search for viz. I'm not seeing any IFC files on Wikihouse repos, but they look old ( https://github.com/wikihouse ). Do you know where they're hosting?

Oh wow, you just sent me down a really intriguing path. I was not familiar with IFC, but looking more into that now. No, it does not look like their repo [0] has IFC files, but I don't imagine it would be that difficult to export the additional needed file information.

I think it's about this solution being easy to make with CNC routers. Traditional framing is not made for automation, so they went to precut sheets of plywood. It's similar to 3D printing: You could make a doorstop in 30 seconds from a block of wood and a saw, or you could print it in 1 hour from plastic. The second option is better if you have no saw and a printer.

It seems like it would be much, much slower to CNC all the plywood and insulation and assemble the boxes and then put the boxes together than it would be to just frame a wall, sheet it and put insulation batts in. Having access to and operating a CNC also seems harder than learning to use a skill saw and hammer a nail. It feels like they're trying to apply abstraction to construction where you just have one unit that…

I remember meeting one of the founders to see if this could help with a project I had 5 years back. Was a great concept and I wanted to buy into it but the costs were high versus a custom build which would give me a better product for my needs. Glad they are still going but not that many projects on their site.

I like the ethos but to me it's pointed in entirely the wrong direction. Why not just make standard sections of 2x4 or 2x6 framing? Start standardizing window sealing details? Literally anything that will actually get some use? Instead we get opensource plywood boxes? Using plywood for all of the structural components means if you get a leak, which all houses get, you are in danger of much more significant damage tha…

what about A frame housing? Is that easier? Don't know much about building house. Just heard it is an easy way to build house with friends and some help.

A 1x6 which is probably thicker is usually around $4-5 a 3/4 plywood at 4x8 is $51 ish, so 8*1x6 ($4.5 at 8ft length) = $36, and $51 for plywood. So no, plywood is not cheaper at apples to apples comparison. If you chop the thickness down you can get it to be comparable or cheaper. But plywood is stronger then a bunch of 1x6.

> A 1x6 which is probably thicker A 1x6 is .75 x 5.5 inches. Plywood is still more expensive with your numbers. OSB may cost a little less than the plywood though.

That would depend on the mill, you can get nominal and actual sized wood. At least I can in Canada get true 1 inch x 6 inch wood.
