I don't disagree, Mscbryk. But my point was that whoever created the 1991 scale-model had the foresight to add that additional wing (which doesn't exist on the real Greystone Mansion) and to include a tower room.
Neither the wing nor the tower were ever seen on the 91 series, yet they existed -- waiting for a chance to be seen and used. So, one has to assume they were created for future storylines that may have "needed" an abandoned wing of the mansion or a tower room. I only threw-in speculation about Adam, Quentin, and Jenny because these characters had been inhabitants of the various abandoned parts of Collinwood. I wasn't really speculating that the 91 series would actually get to these particular storylines. Still, the designer of the scale-model was obviously thinking ahead.
On the other hand, I believe Dan Curtis was planning to "get to" the Quentin storyline much quicker than most of us might suspect. Adrian Paul in an interview just before (or perhaps, just after) the cancellation, admitted that he would be playing Quentin in an upcoming storyline, likely to be initiated during the series' second season.
As much as I enjoyed Adrian Paul in the series, I though it was MUCH to fast to begin the Quentin storyline. And I believed that Quentin should probably be played by an actor not-before seen on the show.
All of that aside, originally I was really just asking if others had seen the scale model and had noticed the tower room and extended wing.
