Perhaps The Sun isn't the best source of information for HN.

You can't trust amazon to sell an SD card why would you trust them to sell a house? How long until amazon's search promotes dozens of Chinese companies each with an unpronounceable name selling knockoffs made of pressed wood soaked in formaldehyde and painted with lead.

It's just a framing kit made of spf lumber. The rest of the house is left to be sourced.

Yep. From the page (capitals are original):

"THIS KIT IS NOT A COMPLETE HOUSE. YOU ARE BUYING A DOME FRAMING KIT Only! THIS ITEM IS NOT IN STOCK AND REQUIRES A 6 MONTHS LEAD TIME."

And we've come full circle, with the ordering of house kits, as one could do in the 1800s from the Hudson Bay Company, from Eatons and Sears.

So what is the minimum cost 1k sq ft home with septic tank? Guy there is quoted as saying he can build for $10k. Sounds like bullshit.
