The idea that periodic replumbing and rewiring and replacing roofing felt costs less overall than a complete rebuild is questionable enough in terms of financial cost, even more so in terms of carbon output cost. Sure, the [carbon] accounting looks a little different if you're having to pull out most of the load-bearing walls to accommodate a change of use and underpin to build on top or considering replacing old masonry with something built to maximise energy efficiency. But rebuilding entire houses to keep up with the latest fads in mobile charge ports and mixer taps is about as good for the environment as "fast fashion"!
