this is my solution to the round roof problem, I had thought of covering it in tiles or 1x1 cheese slopes to give a smooth finish.
About this creation
the 12x3 wedge plates are fixed together and the 12x2 plates are just held in place, as you add the next level you just add more 12x2 plates. once built it is quite stable. The support structure uses various hinge bricks, plates,and bricks, to create the angles required to fix the exterior plates. Work in groups, fixing 2 plates missing 1 which is fixed further up the build by another set of hinge and brick ring. This was the only way I could achieve these builds as space inside is a problem. Hope this helps.

Did you take any other photos?
If the new photos are of no help, l will try doing a strip down build. They look complex because there can be 2 or 3 separate support builds inside. It might be easier now as there's a new 1x1 hinge plate.
Could you further explain how you built the bigger cone like roof piece? I really like it and I'm thinking about implementing the technique into one of my MOCs. I just can't really tell how to do it with just the few pictures here.
Okay, I was just curious. And I agree, I think a perfectly accurate Hogwarts would be nearly impossible! But, I'm also one of those people that has the basic layout of the castle (in the films) committed to memory. I have a few video-games from a few years ago that show an accurate layout, so that is how I'll be doing mine...for the most part!
I don't know I'll just try to best fit each space, so some interiors won't be where there supposed to be. I think I'v already started with the library as I'v put that above the main entrance. I think it would be very difficult to build an entirely accurate internal/external model. but then again I'm no expert I just build what I think looks good.
to anyone trying this you'll find the use of a rubber band to hold the top of the cone in compression a great help. this can be removed as in 2 of my cones or left in place as in the first one, I must be honest it's a hair band of my daughter's it's black and very fine. I did use a grey lego one with the first one but after 2 failed orders for a black one on bricklink I just started looking around the house.
