No, they aren't transferable.
You could ask the creators nicely to invite you to their server so that you could see their builds in person. But, no, they cannot lend you their builds.
Hmm... maybe with enough incentive you could invite them to your server to put in hundreds of hours and build one for you.
Otherwise, you'll just have to be inspired and build your own. It doesn't have to be fancy for you to feel you have achieved something amazing yourself ;)
