How I did Nago's Animation Object

Nago's animation was so easy a cave man could do it. Nago didn't put a lot of effort in his animation. Well that's nago. His only good at art and Basketball. Hahaha just kidding,but no seriously. It was very easy. How I did nago's animations was:
Step1. First but a cube 9 by 10. The height has to be 1 unit. It has to be on top of the grid.
Step2. Second you have to make 8 rectangles. They have to be all the same. They have to be 2 by 1/3. The height has to be 6. The rectangles have to be put in the corners. Two for each corner.
Step3. The roof of the building is a triangle. It has to cover the  rectangles.
Step4. Cover the rest of the grid with grass.
