Here are pictures of the mansion, I personally dub “Illinois Behemoth”, completed. It is located on S Braymore Drive in Barrington, IL. I wrote a post on this home a while back and included photos of it still under construction. Well, its definitely completed and looking mighty BIGGG! So, I just got more information as you can see below. It’s address is 1765 S Braymore Drive. It is owned by Gerald Forsythe, who is a businessman and auto racing magnate. On the property records website, it says that the home is between 1.3 and 1.9 stories, whatever that means, and is just shy of 25,000 square feet.
