A Landscaper Quoted $5,000. He Built the Retaining Wall for $250

Steep backyard slopes often become nothing more than difficult grass to mow. Reddit user u/Liakada saw something different. Instead of paying a landscaper about $5,000 for a retaining wall, the homeowner spent six weekends reshaping the hill by hand, using leftover stone, reclaimed landscape timbers, divided plants, and only about $250 in new materials.

The project cut a winding staircase into the slope, added a dry-stacked retaining wall, expanded the planting beds, and connected the different levels with new walkways. Most of the cost savings came from reusing materials already on the property or left over from previous landscaping projects.

The backyard already included a flagstone patio, planting beds, and a grassy hillside that separated the lower patio from the upper yard. The slope limited access and left little usable planting space.

The retaining wall started where the patio ended, following the natural curve of the hill instead of cutting straight across the yard.

A trench marked the future retaining wall beside the patio. Soil came out by hand until the base reached solid ground capable of supporting stacked stone.

The excavation followed the entire length of the future wall instead of stopping where the grade appeared level.

The trench continued around the hill, creating space for both the retaining wall and the future planting bed above it. Soil piles grew beside the excavation with each section completed.

The wall alignment created a gradual curve instead of one continuous straight line.

The finished excavation revealed the final footprint for the retaining wall. Different elevations became visible before any stone entered the project.

The curve also established the future location of the staircase leading toward the upper yard.

Large flat stones formed the first courses of the retaining wall. Each piece rested without mortar, relying on weight and careful placement for stability.

The homeowner later described dry stacking as solving a puzzle because every stone required the right shape before the next course could continue.

Additional courses extended the retaining wall across the hillside while preserving a smooth curve. Flat capstones created a clean top edge along the entire length.

The planting bed behind the wall expanded as the new grade replaced the former grass slope.

Landscape Timbers Formed the Staircase

Reclaimed landscape timbers became stair treads climbing through the center of the hill. Wood chips filled each step while stacked stone supported both sides.

The staircase connected the patio with the upper lawn without cutting a steep path through the grass.

The completed project combined retaining walls, stairs, planting beds, and new pathways into one continuous landscape. Shrubs, perennials, ornamental grasses, and young trees filled the former slope.

Only the patio extension came from a contractor. The retaining wall, stairs, planting, and landscaping were completed by the homeowner.

Flagstone Connected Every Outdoor Space

Large flagstones linked the patio with the staircase while a stepping-stone path crossed the lawn toward the new terraces.

The stone surfaces created multiple routes through the backyard instead of leaving the hillside isolated.

The dry-stacked wall became both a structural feature and a visual border between the patio and the elevated garden beds. Gravel behind the wall provided drainage, helping support the stacked stone.

According to the homeowner, only a quarter pallet of additional stone was needed because most materials came from previous projects.

The original backyard relied on a steep grass bank between the patio and the upper yard. Six weekends later, retaining walls, stairs, planting beds, and pathways replaced the unused slope with a series of connected garden spaces.

Could you tackle a $250 DIY project instead of accepting a $5,000 landscaping quote?
