When NBC launched an American version of the hit UK show The Office, it started with a short 6-episode season. These episodes were filmed in an actual office building, and used both interior and exterior shots. When it was clear that the show would be a hit, they decided to move to a proper studio.
Scranton Business Park
Chandler Valley Center Studios is located in Panorama City, just west of North Hollywood. The studio has 2 soundstages, so the production built a near exact replica of the original office layout. The building housing Stage 2 became the exterior of the Scranton Business Park, and was featured in most episodes. The exterior and parking lot is instantly recognizable to any fan of the show.
First Christian Church of North Hollywood
Most episodes were filmed in the studio, however a number of episodes were filmed on location. One of these episodes was Phyllis’s wedding, which was mostly filmed at the First Christian Church of North Hollywood. You may recognize the church from shows like Young Sheldon and 7th Heaven. This is where you could see Michael pushing Phyllis’s father’s wheelchair down the aisle, and where he prematurely announced them as being married on the altar steps.
While the show was not filmed in Scranton, the show tried to stay true to the geography. Many local place names were mentioned during the show. The famous “Scranton Welcomes You” sign featured in the opening credits has been replaced, but the original sign has been on display in the Steamtown Mall. The mall, which was mentioned numerous times on the show, also featured a small The Office gift shop, and Dwight’s Bobble Head could be seen on the elevator. This was several years ago so I can’t confirm if these are still there.
