What is the name of the production designer for Up?

Ricky Nierva was the production designer for Up.

As production designer, Nierva helped shape the film’s visual world, including its characters’ environments, Carl’s distinctive house, and the landscapes surrounding Paradise Falls. His work helped balance realistic details with the exaggerated, storybook design that makes the floating-house premise believable within the film’s style.

Nierva and the Pixar team conducted research in Venezuela, whose tepui mountains and jungle landscapes inspired the film’s South American setting. The production’s visual development also treated Carl’s house almost like a character, using its changing condition and color to reflect the story and Carl’s relationship with Ellie.

A common mix-up is confusing production design with art direction. Up also credits Daniel López Muñoz as art director, while Ralph Eggleston worked as a lighting art director. Those are important roles, but the production-designer credit specifically belongs to Nierva.
