This is my SketchUp interpretation of “The Brady Bunch” house. The entry area comes from some research information, but the rest of the house is purely estimated. The house used for the television series was not a backlot set, it was an actual location house. I have an architectural book with some information for a similar split-level house, and I used it as reference to the design.
A house of this general shape is usually a split-level, meaning that from the front door one would go up only half-a-level to the bedrooms and down half-a-level to the garage/playroom/basement. The main living/kitchen/dining level would be off to the right (in this illustration), mid-way between the other two levels.
Of course, the interior was portrayed on screen as a standard two-story house. If one would try to stack the two levels, seen on screen, the upper level would cantilever oddly off to one side. The set design created a house of nearly 4,000 square feet, while a real house of this size is likely around 2,000 square feet. As huge as the interior portrayed on screen would be, there would be nothing under the forward facing gable roof (to the left side) of the house. The style of this house would be called contemporary (even if it is now only contemporary to the late 60s and early 70s).
I’ve chosen a SketchUp rendering style that has the feel of an architectural rendering (since dad, Mike Brady, was an architect). The clouds and logo were added in Photoshop.
