But the team has not yet given up on the project, and will continue to search for a new venue.
"We can make it, we know that, it's just finding the right place to build it," said Adriaenssens at Barry Callebaut.
Barry Callebaut plans to donate the chocolate for the project, and while the eventual installation would likely provide the company with some publicity, Adriaenssens does not expect to make money from it.
"It's just for fun," Adriaenssens said. "Sometimes that's also possible."
For the architects involved, the project also offers an academic opportunity to explore how material can inform design. A report of their chocolate pavilion development is currently under review in the journal Computer-Aided Design.
