Fans of the series who follow Steve Martin on Twitter probably aren’t surprised to learn that “Only Murders in the Building” was filmed on location in New York City, specifically on the Upper West Side. The actor chronicled part of the production process on his social media.
According to Seventeen Magazine, a luxury apartment building called the Belnord stood in for the exteriors of the fictional Arconia building, which is based in turn on the actual Ansonia building. The Ansonia was once a boutique hotel, but now is a condominium with residential space for New York-based students at the American Musical and Dramatic Academy. Interior shots and lobby scenes were shot on a soundstage and not within the Belnord.
According to Untapped Cities, Central Park, The Dakota building, and various streets around the Upper West Side all appear in “Only Murders in the Building,” making the show an honest Gotham experience.
