No, I didn't meant /48 per building, it was only the reply to the "building" thing comment, but /48 per customer, as you say. Regards, Jordi

Are you assuming that organizations never subnet inside a building ?
In IPv6 if you want to keep things working, the minimum network is /64, so if somebody want to subnet, you need to give them something bigger, and current IETF recommendations are still /48, as per RFC3177.
There's nothing in the IETF recommendations that says "per building".
So giving a customer a /48, and having that customer assign /56s out of that space to individual buildings, and taking /64s from there to individual LAN networks, is a perfectly workable approach.
