The house is a product of the strange obsession of one man — in this case, the son of a former governor — his connections, the film’s powerful director and a company that is trying to evaluate with more care the hundreds of requests it receives a month from people wanting to use its characters and imagery.

Bangerter Homes, which specializes in custom-built dwellings, is marketing the 2,800-square-foot reproduction as “The Disney/Pixar ‘Up’ House,” using stills from the film and the official logos of Disney and its Pixar Animation Studios subsidiary. The listing price: $400,000.

So far, serious bidders are scarce. But over the last few weeks about 27,000 people paid $10 each for a peek inside, with most of the proceeds going to charity.

The man behind the design is Blair Bangerter, a son of Norman H. Bangerter, who served as governor of Utah from 1985 to 1993. The younger Mr. Bangerter first saw “Up” two years ago. A longtime animation buff, he said that he was thrilled that the film gave a starring role to his other passion — houses — and became preoccupied with replicating the colorful Victorian in real life.
