To design the museum, Wright created more than 700 sketches until the final draft of the project was official. Wright spent 16 years working on the design, but he died before the building was completed. His design created a lot of arguments as many people did not like it. One person said it looked like "an indigestible hot cross bun", and another said it looked like "an inverted oatmeal dish." Some artists thought that the curved walls and ramps would make it impossible to hang their paintings properly.
