Two-Point Perspective: A Building

Draw a horizon line. Place two vanishing points far apart on it.

Draw a vertical line below the horizon for the building's front corner.

Connect the top and bottom of the vertical line to both vanishing points with light guide lines.

Add vertical lines for the back edges of each wall. Add windows and a door using the perspective lines as guides.

Erase guide lines and add shading—the wall facing away from the light is darker.
