The production design of The Amazing World of Gumball fused two distinct regions: exterior suburban landscapes from Northern California and interior public spaces from London. Below is a breakdown of how physical production sites translated into the show's iconic environments:
| Physical Location | Elmore Counterpart | Primary Visual Markers | Production Era |
