The Clay House is supposed to be Bread

Whilst re reading the story of Hansel and Gretel by the Brothers Grimm, I realised the house is completely made of bread! How do you show that, how would u make something solid enough to be believable as a house, whilst still being made of soft edible bread. Well it was by chance when looking at 18th century German Cottages I found The Clay House in Leshten, Bulgaria. I've also discovered there is a virtual tour of the building. It is made of Flintstone/Clay well to me that does have a few of the qualities I imagine the Witch's Bread House would have, this below is the interior:

Excuse the TV, but it is that dusty brown and the shaped of the bench and house is nearly perfect as a reference to the house. Also it helps seeing the whole thing in 3d so here is the link to the Virtual Tour; http://www.rentbyownerbg.com/offer/1918/

Also found these as extra elements that I want to just keep till I make up a mood board:

Well this is officially the beginning of the research for this Visualisation project.
