      I also live near the mansion in Venetian PA, it is absolutely much more than 13,000 sqft, I remember talking to people working on it being built and hearing it was closer to 24k sqft. So all the comments about that are correct the 13k was a mistake. There are multiple enormous mansions on that road that are all over 10k and this house literally dwarfs them all. Beautiful home though for sure. I have been inside the entryway on a few occasions and it is truly splendid.

    Are you sure the final PA house is only 13,000 square feet? It looks far bigger!

    I live probably 20 minutes from the bottom estate and I have to truthfully say that it is the most impressive home once you actually drive at a street level and survey the entire land (if you can!).

    The Justabout house is amazing. It is out in the country, but only about 9 miles form the city of Pittsburgh. There are a few others close to it that are fantastic, but this one stands out on this road. There are roads that approach it from a couple different angles, it is truly surreal when you see it. The house next to it is for sale and listed at 12,000 sq ft, so I am thinking this house is closer to 25,000 sq ft. There is another 20,000+sq ft home a few miles away that sits on 135 acreas and has a horse stable as big as the house.

    The last mansion is undoubtedly the best mansion by far from this galore.I don’t
    think that it has only 13,073 square feet, but at least 23.000 sq.feet.
    The exterior is magnificent, while the landscaping is gorgeous.It has to be one of the greatest mansions in the state of PA.

    Fantastic post!!!

      I saw this house when I got lost coming home from Trax. It is amazing, I had to pull over. Does someone famous live there? They should open it up and let people tour. I would pay to see the inside of that place!!!!
