I happened across this thread when making a model of this for a friends birthday gift. I'll stress that this was a quick job meant to be approx half size, so it's not an exact replica. Although the smaller size is easier to display and has a 'cuter' quality about it. And it was fairly easy to do off the cuff, so a proper replica should be no probs for a dab hand.
The Sticks on the roof obviously look wrong, but couldn't be cut and retain the original shape. Unlike the sticks used for the under window panels, which have a better size. It’s made from cardboard, papier mache, lollypop sticks, matchsticks, glue, and acrylic paint. The pillars are sawn off pencils. Cheap and cheerful. The base it sits on measures 22cm squared.
It was lots of fun to do.
