I went passed the area again today and took a photo.

The cul-de-sac is called Northfield Gardens (I've lived close by for > 40 years, it's been called that by everyone all the time). You can see in the photo that although there's car access to the first two houses, there's no car access to any of the other houses in the cul-de-sac. It's foot path only.
