Haha! Hey, it is a 2" 24 track...

So if doing a new build, how would that differ construction-wise from a regular build? I understand using two-leaf walls with rockwool between the leaves, burying pvc conduit for lo-z lines prior to pouring foundation, making sure foundation is separate from rest of new build's foundation with a gap-would any of these best practices in a wholesale NEW build drastically change the cost of a standard new build for any old building? That's the confusion I'm coming to... everyone talks about the cost of retrofitting, but there's not much about a wholesale addition with a separate concrete foundation for isolation.
