To be clear I was referring to shared parking with multiple spots. Where I live one underground parking is spanning multiple houses (I go from the parking directly inside), and there are maybe 3 or 4 in total. The provider would do the work "once and for all", considering everything from replacing the transformers for the additional power, to digging up the trenches and installing the upgraded cabling everywhere, and to every parking spot 11KW charger. The assumption behind this is that all the vehicles in the parking might end up charging at the same time (over night) so everything has to be sized for that. The electricity provider normally sells the charger with installation for ~2500E. But that is assuming the end-to-end wiring already supports this. With dozens of chargers to install in the same parking the chances that the rest of the network was already so overspeced and up to the task are slim. The manpower to dig a trench, replace cables and transformers is more or less the same whether you do do it for 10 parking spots or 100. So there's probably a sweet spot between having enough demand to split this between more people but not that much that you need the next level in transformers.
