I recently read reviews on most of the new Harry Potter sets, and I realized that some of them could be used in Castle-building. I just wanted to know what sets you all think are the most Castle-friendly:
Dobby's Release http://brickset.com/detail/?Set=4736-1
Quidditch Match http://brickset.com/detail/?Set=4737-1
Hagrid's Hut http://brickset.com/detail/?Set=4738-1
The Burrow http://brickset.com/detail/?Set=4840-1
Hogwarts Express http://brickset.com/detail/?Set=4841-1
Hogwarts Castle http://brickset.com/detail/?Set=4842-1

Hagrid's Hut has some great wall/tower parts I think Castle fans might like. The Burrow has a lot of nice colors and parts you may find useful for Castle village buildings. I personally thing the Hogwarts Castle is very close to becoming a medieval church, though it is expensive. One solution to the cost of these sets might be if you sell the figures and keep the parts as many people are looking to expand their figure collection for the HP universe. Personally speaking I don't think I'll ever get enough of the color combos of tan, sand green and the bleys.
