Being a huge fan of basically anything that John Hughes was involved with, I was excited to see the neighborhood. The Home Alone house and the house in Uncle Buck are actually located on the same street, but in different suburbs that are right next to each other. It's easy to find the location of the houses because of Google. We also passed through Evanston, which is the suburb where Sixteen Candles was filmed, as well as Uncle Buck.
Once we got to Winnetka, we found the house right away and parked outside of it. It's a very nice house, as are the other houses in the neighborhood. I thought that the house would have been taller up close, but I think it appeared taller in the movie because of the angles it was filmed at. I took a couple pictures of it, which can be seen below:
We ended up going and ringing the doorbell of the house. The owner answered the door and we asked him a few questions. He was extremely nice and told us a lot of information. Billy was interested in whether the owners already had the treehouse that was in the film, but we were told that it was made for the movie. He pointed across the street to show us the Murphy's house, where Kevin runs to near the end of the film and gets caught by Harry and Marv. He then gestured to the house next door to him and said it was the old man's house and explained that the front of that house had been changed. We didn't recognize it and we were surprised at how large it appeared! It looks massive up close! I would have taken pictures of these other houses, but my phone was about to die. It was a spontaneous choice to go look at the house after we went out for dinner, so maybe I'll go another time and be ready to take pictures.
