Although fans know the address of the house to be 11222 Dilling Street, the number on the curb has been changed to 4222 for this series.
The footage of the front of the house utilized throughout the show's 5-year run was shot shortly before The Brady Bunch (1969) debuted. The interiors were created on a soundstage and bore absolutely no resemblance to the rooms inside of the real house.
The tall green vase on the pony wall by the front entrance is an original set piece from the show. It was located in a storage locker on the Paramount lot.
Some of the decor was donated by devoted fans through a scavenger hunt posted online. They included the orange grapes decoration on the coffee table, and the curio cabinet.
