As recounted in the "The Art and Soul of Dune: Part Two," Patrice Vermette had actually based some of his designs for the Caladan castle interiors on pictures of the Brion Tomb and Sanctuary.

An incredibly impressive - for the time - scene in Dune 1984 involves a Guild Navigator speaking with the Emperor, and later making the journey from Caladan ... state-of-the-art in cinema today ...

For a hefty $89.99 price tag, you get the Caladan Palace building set so you can make your base all fancy. You also get the Stillsuit from 2021's Dune film, plus a digital artbook and soundtrack.
