Lego Hogwarts
It took us the length of the 7 Harry Potter movies, the last Fantastic Beasts (which is as bad as the 2 first), Moana and almost Lightyear (20 minutes left) to complete the build. It was probably the most entertaining mega build that we’ve done so far. If the castle was lighter, I would turn it to show the detail of the many rooms that are included. From Dumbledore’s office to the giant chess board from the Philosopher’s Stone, the attention to details is incredible.
