Guild Wars 2

I created a guild and many friends have joined, several were already on a different server.
Everyone else wants to move to the other world, but I read that guild purchases and builds are world specific.
So as the creator of the guild, If I move to another world will everything the guild has built/is building move as well?

you read correctly and I confirm it for you…

you confirm that yes, if I move the builds will move with me?
or that we are screwed and have to leave everything behind?

you read that guild purchases are world specific and I confirm that for you, sadly
