The type of perspective normally used for drawing architectural exteriors showing two sides of a structure is called Two-Point Perspective.

Here are the steps to draw in two-point perspective:

1. Start by drawing a horizon line across your page. This represents your eye level.

2. Place two vanishing points on the horizon line, one on the far left and one on the far right. These points represent the 'distance' in your drawing.

3. Draw a vertical line anywhere between the two vanishing points. This will be the corner of your structure.

4. From the top and bottom of this line, draw two lines going to the left vanishing point and two lines going to the right vanishing point. These lines represent the sides of your structure going into the distance.

5. Decide how far back your structure goes and draw a vertical line between the two lines going to each vanishing point. You should now have a basic box shape.

6. You can add more details like windows, doors, and other architectural features by using the same principles. Always remember that lines going horizontally will go to one of the vanishing points, and lines going vertically will be straight up and down.

7. Once you have all your details, you can go over your drawing with a darker line and add shading to give it depth and realism.

Remember, practice makes perfect. The more you draw in two-point perspective, the better you'll get at visualizing and drawing it.
