Just by a few inches at the most.. maybe one brick worth. The row of 8 houses were built on a gradual slope, with the private road running down hill to a drain at the bottom of the road. So they are all slightly lower than the last as they go down the road, with ours being the 3rd from the bottom. The house to our other side, which we are not connected, is quite a bit higher though, maybe 3 bricks worth, and they didn't flood.
