I subsequently added two more big boxes. Box 5 connected boxes 1 and 6 and box 6 connected boxes 2 and 3. Box 4 was still a stand alone box. I wrote blog posts on this configuration here and here.
The first noteworthy play space was on top of the apparatus. Since the space underneath the boxes was highly constricted, the top of the big boxes became stable platforms for the children to do their operations. That was especially true if they wanted to transport the pellets between large containers and between different levels.
The second noteworthy play space was the floor. In the video below, the child used the floor as a platform for her operation. Again, since the space underneath the boxes was highly constricted, she placed three metal containers on the floor so she could fill them.

However, getting the pellets in her measuring cup to pour into the containers was not such an easy task. The child had to keep her balance as she twisted her torso to reach over the lip of the table and under the box to scoop pellets in her measuring cup.
Another feature of the floor that made it noteworthy as a play space was that, as a platform, it was expandable. Below, the children have taken over the floor space between the apparatus and the cabinets for their play. There was no way they were going to be able to do their "cooking" in the highly constricted space underneath the big boxes over the table.
Play spaces are important to children. The more intriguing the better. Though some play spaces seem to be highly circumscribed, the children find spaces on and outside the margins of the defined play spaces. Those spaces outside the margins are noteworthy because the children create new meaning as they embrace and inhabit them.
