I used chocolate cake covering to glue the walls together, which was a genius idea from Susan, which she first used with her Valentine house. The cake covering sets really quickly so you don't need to support it for ages with tin cans, as well as tasting a lot better than royal icing. As always though, the walls never end up straight however carefully I cut them, which doesn't help when it comes to assembling - another good reason to use the cake covering as gaps can be filled more easily.
I bought a pack of cheap plastic Halloween accessories from a pound shop along with some chocolate ghosts, Haribo sweets and chocolate fingers which were used to decorate the structure.
