Architectural Digest has a list of the “26 most Iconic TV Interiors” and it includes at least two McMansions:

The Sopranos memorialized early-2000s New Jersey in all its gritty glory. Perhaps most memorable among fans was the Soprano family kitchen, with its light wood palette, where Tony was often seen in his robe, rummaging for cold cuts. But the show’s production designer Bob Shaw has said he found the office of Tony’s therapist Dr. Melfi the most interesting, because it was round. For a mobster confronting his own mind, there was nowhere to hide…

The rich and beautiful but down-to-earth Cohen family was the family every O.C. fan wished would adopt them—but only Ryan was so lucky! The Italianate McMansion in Newport Beach, California, was actually built on a soundstage—so, that breathtaking ocean view from Ryan’s poolhouse? That was a photo backdrop made by production designer Thomas Fichter, who was also responsible for all the “weather” you ever saw on the show.

I have a lot to say about the Soprano McMansions here.

The home from The O.C. has some similarities to the Soprano’s McMansion: it is in the suburbs and was built (and aired) in the same time period. Yet, the inhabitants of Orange County on the show faced more conventional suburban problems – teenagers stuck in a world of largely successful adults with big houses – compared to the twist of a gangster family living in a well-kept New Jersey McMansion.

Two other thoughts on this list:

-There are at least a few outright  mansions on here, including the impressive setting for Downtown Abbey.

-The brief descriptions do not provide that many insights as the list contains mostly very popular shows. Did the interesting setting help make the shows popular or did the settings become interesting because the shows took off? The list does not really have any failed shows though I imagine some short-lived television shows had some very interesting interiors.
