Thanks for the comments, I think the extension on the front facade add a lot to the set, I also think it looks grander and more what a TH should be. I've not decided on an interior yet, it will have something just need to work on some ideas but any suggestions are welcome.
Its going to be three floors like the original, don't have enough bricks to make it larger at the moment plus a fourth floor might make it look too tall. I've completed the 2nd floor exterior, wanted to add more windows to the sides but need to buy some
