THE CHALLENGE:

Building a home on a hilly lot can be a challenge—and this Alabama house is a perfect example of making the most of a hilly lot. From the moment John Pearson Homes came onsite to start construction on a 21,000 sq. ft. single family home, it was clear that some serious retaining walls would be required.

However, the aesthetics of the retaining walls needed to enhance the home’s aesthetics. Seeking to minimize excavation as well, the architect turned to Redi-Rock.

THE SOLUTION:

“We basically used Redi-Rock to create the lot for this house. The grade changes were so severe that we needed some massive walls to create a level area around the house,” explained John Pearson of John Pearson & Son Construction, the company that built the home.

Redi-Rock is a large block retaining walls system known for the ability to build tall gravity walls and even taller reinforced walls that will stand the test of time. Since the project required both reinforced and gravity walls, it was a great choice for the project. The architect chose Redi-Rock’s Cobblestone texture to match the aesthetics of the home.

“The house is painted brick and the walls actually touch the house in some places so the Cobblestone texture really looks great with it,” Pearson said. “The owners are very pleased with the look.”

The project included a total of three Redi-Rock walls—two were reinforced to support the house, and the third wall was a gravity cut wall to make room for the driveway.

The reinforced walls stood 30 ft. at their highest point, and the gravity wall stood 12 ft. at its highest point. But even these impressive tall walls are not the focal point of the hardscapes at this project. The most eye-catching portion is the spiral staircase created by two reinforced barrel walls.

The inside barrel wall of staircase was 18 ft. tall and was created using Redi-Rock half blocks to make the tightest possible radius. Each of these half blocks reinforced with geogrid. The 35 ft. tall outside wall of staircase was created using retaining wall blocks at the bottom of the staircase, with three-sided freestanding blocks topped with caps at the top to accentuate the outside rail of the stairway.

THE OUTCOME:

The owners of the home were very pleased with the way the Redi-Rock walls turned out, and for the level lot they created.

In total, the project required 9,500 sq. ft. of Redi-Rock.
