I'm pretty confident that house will be standing in some form for another 70+ years. Most of the crap they build these days not so much..Very true!
If some doesnt understand the best example I use is the old frog bricks they used then v now. The former a few hits with a mallet hammer and it would struggle to dent it, the latter would smash a fist size hole through the wall. One almost like a small concrete block, the other mostly just air.
