Cellular Construction
Mr. Dan Plumbob
Patche & Splinte, Architects
Dear Mr. Plumbob:
We are pleased to inform you that we have chosen your firm to
design our new Megalopolis factory. As you know, I have always
been fascinated by the biology of cells. Therefore, I have decided
to model our new factory after the cell of an animal.
Your job is to design each part of the factory so that it
represents a cellular structure. I have faith in your firm’s ability to
complete this project.
Sincerely,
