1. Suppose that you’ve already got the HL, the VP, and a road on your canvas. Since the location of the HL and VP doesn’t change when you’re drawing different objects in a same perspective drawing, you don’t need to draw them again.
Otherwise, you always want to start with drawing the HL and the VP when you draw in one-point perspective. X

2. Step 1: Draw the closest side of the box (a rectangle/cube)
Remember that in one-point perspective, surface that face the viewer appear as its true shape, so the closest side of a box would be a rectangle (or a cube) X
Step 1: Draw the closest side of the box (a rectangle/cube)
Step 1: Draw the closest side of the box (a rectangle/cube)
(1) Draw the bottom of the rectangle. Here you need to decide the location and the width of the box. It doesn’t matter where you want it to be. But once you decide its location, you need to compare make its a proper size in relation to the road.

3. Step 1: Draw the closest side of the box (a rectangle/cube)
(2) Draw other edges of the box. Here you need to decide the height of the box. As a house must be higher than the viewer’s eye level (supposed that the viewer is standing on the ground), the top of the must be higher than the HL.
This relates back to what we learned about the HL. Go back to have a revision if you find it hard to understand.

4. Step 2: Draw perspective lines by connecting all the 4 corners to the VP.
Perspective Lines are lines that are parallel in real life but converge (at the VP) in a one point perspective drawing. Creating these perspective lines automatically makes the drawing seem more real and three-dimensional! X

5. X
Step 3: End the box.
(1) Pick a logical place to end the box. Lightly draw the lines that are parallel to the font edges of the cube, of which the endpoints fall on the perspective lines. These lines represent the rear edges of the cube. Notice how these final lines in the back are parallel to their coinciding lines in the front.

6. X
Step 3: End the form.
(2) Decide which lines are visible by imaging solid surface(s) that are closer to the viewer than these lines (the blue part). All edges hidden by the surface should not be shown in the drawing (supposed that the box is a solid one).

7. X
Step 3: End the form.
(3) Only keep the lines that are visible and erase away the rest of the lines that are not visible.
(When you become familiar with the steps, you could skip Step 3-(1) and (2), and directly draw the visible edge(s) at the rear of the cube.)

8. Step 4: Darken the receding edgesX
Step 4: Darken the receding edges
To make the box stand out, you want to make its edges that are visible to the viewer darker than lines that you use in the intermediate steps, like perspective lines (in grey). In this case, you want to darken the edges on the right side of the box that are receding back from the front side.

9. Step 5: Clean up perspective lines.X
Step 5: Clean up perspective lines.
When drawing in perspective you’re always going to end up with some extra lines or lines that are too long.  You can draw all lines lightly first and then ink things later on when you’ve fixed up the drawing. But, you don’t want clean up the HL and the VP until you finish the whole drawing!
