WIP - Manoir des Beauvais in its medieval state

This is a WIP project. I want to create a short web documentary about the Manoir des Beauvais, located in Dol de Bretagne, Brittany, France.
This rural mansion was erected in the XVth century and stayed in its rough state until the mid 60s, when it was classified as a Historical Monument.
As the town of Dol expanded quickly at that time, the mansion was "swallowed" by the urbanization. It was bought by the town and was heavily restored. Unfortunately, several dependencies were destroyed in the process, and the mansion itself was modified quite a lot.
It is now used as Dol's Youth and Cultural Centre.
My intent here, based on the most ancient photographs and maps available, is to recreate the mansion in its rural/ancient state, then to create a short video about its history, stressing the differences between the original and the current state of the mansion.
Here, the mansion was modeled in traditional polygonal method, with Blender, and textured in 3D Coat. The final animations will all be done in Blender.
