There is a law concerning (obviously) national monuments but also "classified sites." These can be old famous cafés, buildings or all sorts of other things. When a site is "classified," you cannot touch any part of the classified décor, although you can put up walls to mask it (and it is amazing how many places have done this -- there are often treasures hiding behind sheetrock in France). But frankly, the walls shown above have no historical or artistic value, as far as I know -- not even a "Haussmannian" façade. So some other rule is at work here, because I sincerely doubt that it will save any money for the construction company to work behind these walls and windows instead of pouring new concrete.
Ah Kerouac, it wasn't posh enough for the bankers, you know how they like to spend our money. Note the building down the street which looks like a pile of galvanised buckets. designed by the same man who "designed" the Beaubourg centre. Cynical, moi

Mossie, I saw a video recently demonstrating the fine control of these monsters. The machine was just like the one in the last photo. The operator trundled it up to a table set in the rubble of a demolition site,then tipping, twisting and manoeuvering the jaws, made the machine open a water bottle and pour some water into a delicate glass and raise it in a "cheers" to the building project.
