Fairy House Birthday Cake

A friend rang today in a panic, she needed a birthday cake for her niece (her sister had asked her to order and she forgot). As she was buying her niece a fairy door I thought a fairy house would be fun to do. 

It's a chocolate biscuit house, made in an odlums porridge tube, so about a foot high. Everything is edible. P.s. Someone please buy me a fairy door lol, they are cute as a button.
