This month's Over The Top award goes to:
Xanadu on Oberlin
You know the one.
Just so you know, that 1.23 acre tract is zoned R-6, which allowed the 13,022 (heated) square foot house to use a maximum footprint. You can see how that looks quite easily by tracking the depth and girth of this project from the road.
This property changed hands twice, first in 2003 and then again in May 2005. Looks like the occupancy permit for this single family home will be coming up soon, the landscaping has begun.
To help you with perspective, 3 doors down is St. John's Baptist Church, which weighs in at 2 acres and 16,773 square feet.
