That begs the question, in what way are they speeding it up?

Through standardized base design that you can modify. In the same way that having the source code for vendor software often speeds up software development.

Great idea, to design a house nowadays means you need to do a lot more mandatory calculations. For example a wooden beam between insulation has to be calculated, where a few years ago we could pretend they did not exist. Builders are now switching to some sort of engineered beams (two square beams connected with board). To offer this work in the public domain could reduce the cost significantly. However, watching the…

Looks mostly UK based from the projects section.

Also if you scroll down on the main page WikiHouse is a non-profit registered in England & Wales, and their "sponsors and partners" are very dominated by UK organizations.

This looks cool, I'm just wondering if something like this would pass a building inspection in the US?

I would hope the open-source nature of it would mean the designs would evolve until they would pass a building inspection in the US, but I also know nothing about building inspections in the US.

Hi, architect here. Wikihouse has been chasing many of the dragons we've been collectively chasing in AEC[0] for... a long time. Seriously I wish I had time to reply to every single comment here because there are a lot of excellent critiques (not just of WH). It shows what kind of communication problem we have in AEC that even the critiques that HAVE good answers within their weelhouse aren't adequately addressed by…

I've been hoping someone with the right knowledge would do a public update to the Segal method. The stuff that's widely documented wouldn't meet modern code or work as well with modern materials, but that's probably fixable. There also was apparently significant refinement to the methods over time based on lessons from the field and changes in available materials, also not well documented. The core idea still seems good though and with updates it could be an answer for how to lower the cost of backyard cottage type construction.

They claim "If your project is in the UK, USA or Netherlands, we can connect you with a WikiHouse structural engineer" [1], so probably?

Or perhaps if you're prioritizing things other than maximally efficient use of materials? It seems like they're prioritizing standardization, especially of methods, more than almost anything else. AFAICT we have far more excess material than excess labor, so it doesn't seem particularly crazy to me?

“It is freezing honey” “I know dear, but the house was built efficiently”

Not very apt; The accusation here is that the insulation use is overkill, which just means you are installing (and paying for) more material to yield the same performance as less material.

Seems pretty expensive to make everything out of pure plywood. Does anyone have a sense of how cost compares to 2x4's plus drywall? I assume either construction method will need exterior cladding and insulation.

You're correct - but wait until you meet their other friend "milling the panels." Doing it out of plywood is one increased level of expense and difficulty - machine and operator time is an exponential multiplier. Think about it - you're taking a system that could be a guy with a table saw ripping a piece of ply in a minute tops and turning it in to a guy standing and watching a mill run through a piece of ply in who…

Not only that, but in order for the assembly process to work the modules must apparently be "fabricated to millimetre precision". At a certain point, wouldn't this inevitably mean that the QA process would result in some of the yield having to be discarded as unusable after it's manufactured? Seems like a lot of waste compared to conventional methods using (literally) run-of-the-mill lumber and someone's design expertise, though I guess the argument is that architectural expertise doesn't come cheap and using a "framework" scales better in that respect.

In a stick built house you're paying a lot of labor. Material prices are not that much. For example, the material list for a 3 bedroom house is 130k. https://www.menards.com/main/building-materials/books-buildi... Say the land is 130k in your region. You won't find 3b houses for less than 360k. If you're looking at not so cheap builders, it will be 500k. I think there's a revolution coming in the way we build houses,…

For stick frame houses, around 10-15% of the cost is framing. Finishes account for the bulk of the cost.

well yeah, because everything is so bespoke: plumbing, electrical, windows, doors, drywall, trimming. I hope to see some kind of evolution of housing where these things are not installed by skilled labor somehow.
