Amazon just needs to sell DIY houses now.
Imagine if the house came as a series of 3/4" plywood sheets, pre-marked with cut lines; you cut out the pieces, then they are assembled slot/tab style into a home using an instruction booklet (plus glue, nails, insulation, etc to complete). Almost like a flat-pack home delivered in a 40 foot container or a flatbed trailer.
That could be the "base model"; there could also be a model where you purchase a custom 4x8' bed CNC router table. Feed it "blank" 3/4" plywood sourced locally, and it cuts out the parts from plans "in the cloud" or in some other manner. Parts are assembled in the same manner.
Final level (?) might be an on-site crew to assemble it, if you don't have the skills or time to do so yourself.
Only thing you'd have to supply otherwise would be a foundation; this could potentially be concrete slab, or maybe wood or other material raised above ground on pylons cast from concrete or made of native materials (or, maybe it too could be included in the kit?).
Kinda pie-in-the-sky, but the concept of building such a house has been prototyped (first saw something like this in the book about the MIT Fab Lab), the software and hardware all exist; in theory you could DIY this whole solution if you wanted to today (you'd have to create your own custom home design, though - that's where it would be tough).
There'd also be the maze and potential rejection of homeowner's insurance for non-standard construction (similar to what people building straw-bale or rammed-earth houses face), or rejection for the same due to strict codes on construction allowances for the home site...
...which is probably why it hasn't been done yet.
I think self-assembling DIY house would be a huge game changer.
You can only build in/live in homes that are "up to code", which they've written to be compatible with only the types of homes that they build.
In the name of public safety or whatever.
RVs, mobile homes, etc are all illegal to live in in many counties and towns. Local ordinances enforced by crooked small town cops and officials.
If it didn't exist, there would be no real reason to live in an apartment or house. Most people's needs are wayyyyy below that cultural standard.
hopefully I'm not murdered for this post
