interesting, where would one have to look to learn and/or get the necessary data to pull that off?

i might just want to do that for my own private use (or i might be okay with law infringement).

probably start with finding out who owns / manages the building you want to use (public record, company reports)

if they like your project and see some value in it for themselves, they might even give you the contact of the designer / architect to get files
