This is a collaborative work with Noobricks.
The HP Castle Platform is composed of a 48×32 base and some mini builds that can be combined with the 2022 Harry Potter Hogwarts Castle sets to form an enclosed castle structure similar to the medieval theme.
The official sets you would need to combine are 76386, 76387, 76389, 76398, 76401 and 76402.
Most of the structures from the official sets are not changed so that it would be easy to change them back to the original set up, if you want to. For those that have minor changes, there are no parts that are added or removed so that they can be returned to their original build, if you decide to.
The total pieces required is 345 pcs. and the structure is 15.1 in. wide x 12.1 deep x 23 in high when completed.
