Of course our first submission would have to be NJ, but I had to add this while I still remembered. Anyway, before I start, since this is a house, I cannot tell you what street or around what area it is located. I do not know the house owners, therefore, I can't allow my visitors to harass them.
But that aside, there is a home in NJ that is sort of mushroom shaped, and looks very top heavy. The base of the house is very slendor and long, but at the top, where the attic would usually be, it juts out over the sides quite a bit. The house is white with a grey roof, and the windows are nicely decorated. The other houses in the area are normal shaped, but the area around this house is cleared away, as if to bring attention to it [as if you could miss it], or maybe in case a strong wind comes the top heavy looking structure doesn't tip onto another house!
