That we're still looking at a decade from now to completion, given that the Burj Khalifa took 6 years from groundbreaking to opening, is a testament to how much of the work of the Sagrada Familia doesn't scale. The challenge isn't "the building" as a structure -- it's that every single surface in (and on) the thing is a unique sculpture. I don't think "cutting corners" as a negative -- it's realistic, if you want to ship. Nobody who said "let's build a new church here" lived to see its completion. It's awesome to see, however impractical for 99% of solutions, the occasions when a "screw time and budget -- this thing is going to be perfect" approach is followed through.
