1. Perspective Lines
Use the rules on perspective and vanishing point to establish the basic structure of the building. Keep in mind that this house has two front corners. Create the second front by extending one parallel line just above and below each top and bottom line.
On the right side, draw an X from corner to corner of the two vertical lines. Draw a vertical line through its center to determine the height of the roof. When you connect the top of this line with the left point, the roof will be established. To situate the second floor roof, extend a vertical line up from the first floor roof as shown.
