The Kimera Underground Park, which is the main setting of Billionaires' Bunker season 1, was built on sound stages at Tres Cantos. It took a few months and a lot of set pieces to put together this megaset, which is more than 7,000 square meters.

The set was made to look like it was made in a minimalist style after World War II. It gave the show a tight but luxurious atmosphere. The luxury lounges, spa areas, and secret rooms in the bunker set added to the show's focus on the stress and secrecy inside the bunker walls.
