#2Seems 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.

When I choose a concrete slab foundation, their price estimate tool gives me a range of £NaN - £NaN. Representing currency as a floating-point value strikes again.

Since it’s a UK company/project they will be primarily comparing to brick costs since that’s what the vast majority of UK houses are (still) built with. They claim comparable cost as brick/block construction. £230/sqm.
They also seem to be touting their accuracy and since plywood is dimensionally stable (well, more so that 2x4s anyway) that’s probably why ply.

#5So, $1M USD for a 1200 sqft DIY house? No, thanks.

It's cut on a cnc router table, which does not handle regular wood very well. The dimensional stability and anisotropic nature of plywood is a better fit for most automated cutting methods. If you try to CNC route most regular dimensional lumber it has pretty bad tearout and splitting unless you use a really fine cutter and go slowly (which takes forever).

did you maybe type 1200 square meters? i'm not getting that price at https://www.wikihouse.cc/cost

The most expensive configuration I can find for that size (111 sq m) is 327,000 GBP on the cost estimator: https://www.wikihouse.cc/cost
Maybe you put in 1200 sq m instead of converting from sq ft?

Typical Javascript strikes again?
