Daddy pig's office/work building is a location in Peppa Pig. It does not have a specific name. It is located somewhere in Britain and Daddy Pig, Mrs. Cat and Mr. Rabbit work here. Peppa and George have visited this building in the canon episode "Daddy Pig's Office", as they explore what Daddy Pig and his colleagues do for a living at work. Daddy Pig gets paid for working here as does everyone else who works here. Miss Rabbit also works there as the receptionist.
In Peppa's Adventures: Next Generation, a grown up Peppa Pig works here with the Goblin serving as the boss. A grown up Rebecca Rabbit also works as the receptionist now.
