Here is a series of three drawings showing the steps of a one-point perspective which is from my book Exploring Perspective Hand Drawing. Above is the finished drawing where the pattern was rendered on the floor, cabinet and chairs. A combination of line and stippling was used to create the different values and textures. Below is the first drawing that was started with the large rectangular shape representing the ceiling and wall lines. A single vanishing point was added five feet up from the floor line and in the center.
The back wall is an elevation that has a scale. The short lines on the left wall each represent a single foot. The furniture and accessories were started with a rectangular or square flat front; the vanishing point was used for the perspective lines; and the depth of the items was estimated.
In this drawing, the pieces were refined in their shapes and details were added. The plant and container were drawn on the cabinet top, the drawers and doors were added on the cabinet, and the chairs were defined. The single vanishing point continues to provide the angles for the sides of these items.
