You don't have to start levelling them up at the same time. If you collect resources often enough, you can start building new 800k building every 34.6 hours (11 farms) or 31.7 hours (12 farms), or even faster if you're in alliance.

So, yes, you could build all four shrines at the same time, which saves quite a lot of time.
