The exterior of the home is shown as a ranch style, possibly a split-level, but clearly not enough height to accommodate a second storey. Yet interior shots show the main level as only a couple steps down from ground level and a full storey up from there, and even an attic up from there. The exterior and interior are severely inconsistent.
Each time the front of the Brady house is shown as though it were "evening", the same shot is used for "daytime". The evening shot of the house is only darkened. The same shadow that can be seen in the daytime shot in the lower right corner (caused by the roof) is seen on the evening shot.
