The Baudelaire home was an expensive property most noted for its large private library that held "books on every subject". In the library, there was once a group of books that Bertrand and Beatrice Baudelaire kept on the top shelf that included an atlas, romance books, and war books. When Klaus, at a young age, managed to get the atlas from the top, but was ruined when he and Violet left the window opened and rain came in. Their mother said the atlas was "irreplaceable." It is heavily implied that these books were related to VFD.
Several dinner parties were hosted in the mansion, in the dining room, with a wooden table that was described as handy for unrolling maps, completing jigsaw puzzles and tracing photographs, though it was necessary to use a coaster underneath a drink so as not to leave a ring on the wood.
Violet also may have her own inventing studio somewhere in the mansion.
The property contained a secret passageway leading to the penthouse apartment of Jerome and Esmé Squalor, 667 Dark Avenue. The purpose of this passageway was to direct members of V.F.D. to a safe place before the schism. This passage is the reason why Jacques Snicket had urged Jerome Squalor to buy the penthouse at 667 Dark Avenue.
- In The End, Ishmael mentions that Captain Widdershins searched the wreckage of the Baudelaire Mansion and discovered the Duchess of Winnipeg's ring, only to lose it later in a storm at sea.
- The creators of the Netflix adaptation once made a mini-version of the mansion and set it on fire.
- In the film, the Baudelaire Mansion is situated at 28 Prospero Place, Boston, Massachusetts.
- There is a street in Herriman, Utah named "Prospero Lane", with a cul de sac branching from it named "Prospero Court"
- The street name "Prospero" is likely a reference to the V.F.D. ship of the same name.
