What kind of concrete construction are they using? Straight up reinforced concrete? Or something like ICFs? Or maybe mortar joined cinder blocks? Do you maybe have some links I could read up about that?
As for brick veneer, I dunno really about its durability. It definitely is less susceptible to decay than traditional wood siding, but I don’t think it’s any better than cement fiber cladding, or other modern non-wood materials. Additionally, if anything goes wrong with it, I think it’s much harder to fix it in a seamless way, unlike other most types of siding, where you can just repaint them after repair. I have it on half of my house, and I can’t say I’m a huge fan.
Interesting note on the brick veneer. Even if they are not structural I think they are more durable than other types of siding.
