What a lovely idea for a local history project. The students would love this and the fact that it would be entered in to a competition would serve to really motivate them. I love the idea of the students visiting places that they are going to build to get a real sense of the scale and size of the buildings and it is brilliant that they can visit this so easily. I think it is also a fantastic idea to have the NPC characters to represent some of the people that are involved in the building. this is definitely something i will do in future projects. The kids would love dressing and designing these characters. I would love to see this finished video at the end of the year if you get around to making it please let me know. Well done.
