This 770 model was made from almond milk cartons, egg cartons and cardboard! The only tricky part I'd recommend skipping was the rounded window.
To start cut out an egg carton into bricks. If you make them all the same size yours will look even better! My daughter wanted to do this step herself. When you paint it, try to paint just the bricks and leave the spaces between the bricks unpainted for more of a realistic touch.
The roof was made by cutting cardboard like in the picture below which I took from another blog.
