I have the game and I've looked everywhere and, you can't build one
Yes, if you go to the bank in Diagon Alley you will see that it says 'bonus level' and it will also say Lego builder part 1 of 4.
No, they stopped on the first Lego Harry Potter game for some reason. I was dissapointed.
Go into Gringott's bank where you have to learn how to build levels and play bonus levels.
Harry Potter and the Chamber of Secrets has an ATOS grade level of 6.7.
It's in Diagon Alley after you complete the first level.
When you beat a Bonus Level in Gringotts, pick the Level's Lego brick up again. It will let you build your own level over that one.
There are many Harry Potter games so be more specific
You break a barrel and then you build a broom and you go and clean it up
You can buy it, and teachers know how to do it.
i think its level 4
The last level is the end of the game. Which part of the level are you having trouble with? The giant at the gate? Remember your cloak....
Level up
