About this 3D model

A friend of mine was having a house warming party. I couldn't think what to give him as a gift, so I found his house on Google street view and made a model of it as a money box. I had to guess what the back looked like from the aerial view. I don't know how common this type of house is, but someone else might want a copy. The bottom has a coin operated (ironic) bung to open it.
