Basement Windows!

I use the pool tool one or two spaces wide, next to a convenient ground floor wall and make sure the basement meets up with it. Then I can place windows all along the pool sides, rather like the side of an aquarium!                  I usually put one of the short fences around the other side of the pool so that nobody swims in it!                                                                                                    It's a useful way of making a swimming pool basement as a snack area too, with tables and seats alongside the large glassed pool windows!
