/diy/ - Do It Yourself

>>2770036
I've seen ICFs, but I've never thought of doing the inverse. This shit actually looks pretty neat, you could build a fucking indestructible fortress with these all by yourself lego block style and put the rebar in and just pour away... That's basically what we would call a sandwich wall (two layers of masonry filled with insulation in between) all in one block. Getting tradies to build that shit in my corner of Europistan would be 200 bucks a square meter in labor alone for the three separate parts of the wall plus a ton of time wasted meaninglessly. I wonder how much that shit costs because even if it was a third as cheap as actual cinder blocks I'd be thrilled, it'd be a major contender for the material I'll eventually be building my dream house (a neogothic castle Strawberry Hill/Braziers Park style) with.
