The road to commercialization, page-26

I don't see a reduction in brick stacks.
All I see is a reorg.
Note along back fence of top picture there are 2 long rows tightly packed, and in the bottom picture there is a large collection 6 deep and 15ish long
Someone keen can count them if you like. But it isn't possible to tell how high they are stacked so it is all a bit moot.
Me, I'm convinced there isn't a significant difference.

In any case, surely the 10 houses that will be built will not be built with used bricks.
Unless only the 10th "Full Home Structure" is a commercial build on a real site, and the other 9 are merely built, torn down and built again out the back of sultana rd. Looks like in the IPO documents that it could be possible to read it this way.
