Question

Firefly ignores structural edits like “add a third floor”

  • I’m using Adobe Firefly image-to-image to remodel a building photo.
  • No matter how clearly I prompt it, Firefly will NOT perform structural changes like adding a new story to a building.
  • What I am trying to do:
  • Take a 2-story townhouse photo
  • Add a full third floor on top
  • Add windows on the new third floor
  • Keep the same camera angle and neighbors
  • What actually happens:
  • Firefly only changes surface textures and colors
  • It ignores instructions like:
  • “Add a third story”
  • “Extend the building upward”
  • “Remove roof and build new floor”
  • The building always stays the same height
  • It behaves like it only supports cosmetic edits, not structural ones
  • I tested:
  • Very explicit prompts
  • Step-by-step construction style prompts
  • “Priority: building height increase”
  • Negative prompts like “no two-story building”
  • None of these work.
  • Expected behavior: Firefly should either:
  • Support structural edits like adding floors, OR
  • Clearly warn users that height/structure changes are not supported
  • Actual behavior: It silently ignores structural instructions and only edits textures.
  • This makes it impossible to use Firefly for:
  • Architectural concept design
  • Adding floors
  • Massing studies
  • Vertical extensions
  • Please clarify whether this is:
  • A bug
  • A model limitation
  • Or a missing feature that needs to be labeled clearly
  • Right now it looks like a bug because Firefly accepts the prompt but does not follow it.

Hello @canis_aleu,

Thank you for your message. 

Firefly is generally not good at architectural changes or counting. What you are doing encompasses both of those.  I have had more luck with Nano Banana using it to add floors or make other architectural changes, if your use case allows for that model to be used.

Thanks,
