That might be an object that has been enlarged using the bracket key. It sort of looks like one of the video game systems, but I can't tell what it is for certain. It could easily be something else. Since the pics you attached are from Map view, can you take one or two from the lot and post them here? That might help identify what it is. Objects that get enlarged like that are hard to delete since you have to find the anchor point to grab it. But if you keep trying until you get it to highlight, then you can grab it and delete or resize it back down to normal size.
Another way to deal with it if you have a copy of the lot in your library is to bulldoze the lot and replace it with the copy that doesn't have the enlarged object on it. You can also try saving the lot to your library as it is and replace it with the copy. Sometimes, enlarged objects that extend off the lot as this appears to do, will either delete or go back to the original size when you place the lot again.
Hope this helps.
