My model caused by from the intersection of routes in one week. Which is a kite overlapped with trapezium. I think it looks similar to the roof of the Sydney Opera house. If you look at the picture on the paper is similar to the visual side of the model.
The model has a length of 9 inches,height of 4.5 inches, and width of 2.7 inches. The outline of model is the way from door to the TV ,the TV to middle room and the middle room to the area in front of the sofa.
