When Patrick Barrett built his striking, hilltop home in Des Peres 15 years ago, he loved everything about it. The gorgeous stone architecture had a timeless European appeal. The views of the surrounding countryside were spectacular. There was one thing, however, he hated. The ugly 15-to-20-foot retaining wall that was designed to re-enforce the hillside to install a swimming pool just outside the home’s walkout lower level. Not only was it unattractive, as the father of five active children, he viewed the drop off as dangerous.
