They are talking about wrapping a sandwich in a fast food restaurant. I didn't get what they mean by building a crown in this context.

When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

assembling the top part of the sandwich/burger
If you look at the image on this page, you see the heel, club, and crown.
It looks like the "crown" includes things like the top patty, lettuce and bun

I guess you could use “top bun”
But if it’s like a Big Mac in the photo, there is also another burger. You could say “top part”, “top half", or something similar.
| Nice one. Thank you. Could I replace "Crown" by "The top bun"? |
| agree |

: Based on your reference, it's the top bun and nothing else.

| I liked this one. But I don't know if it should be translated this way. |

So just simply
adding the "crown" or top bun to the burger OR crowning the burger with the top bun
