We built two pools for two different houses. The first pool we built was in Cincinnati Ohio behind our house in Mt. Airy. In retrospect, the yard was a little too steep for a pool in that case, but we added retaining walls and built it anyway. The backyard in Mt. Airy was a hill, then a small flat area that backed up to the house. It was the first, and so far the only house my wife and I have ever designed and built.
In Indiana, we added the pool to the much larger backyard. Amazing what moving from a crowded, and larger city to a suburb of a smaller city will do for you. The funny thing is, in Indiana, we had to add retaining walls for the pool as well. In Ohio, it was to create a flat space for the pool (who knew pools couldn’t be built on the slant of a hill. Seems strange to me ?). In Indiana it was to have the same flat platform for the pool.
Our Indiana backyard was an undulating set of hills. The retaining wall almost gave us an infinity pool look and feel, except that the wall rose just above pool level. The second retaining wall allowed us to have a nice patio area for the pool. We nearly added a staging area/screened in porch under the deck by the back door of the house, but decided against doing that twice. The first time we decided to wait and the second time we decided we didn’t need it!
