Location scouting

Today I spoke to my teacher about how I would like to shoot some of my trailer at Wallington Hall as it is a grand house and how it reminds me very much of Harry Potter. As it is an old house I think it would be a creepy location and will improve my trailer. I plan to email them to see if I am allowed to film there as I am unsure due to it being the national trust. I also spoke to my teacher about filming in the Newcastle library as there is a spiral staircase. I will go and see if it is a good place to film as I have never been to that library before, if I think it will be a good place to film then I will also ask if I can shoot some footage there too.
