Hillside specialists for Southern California's most demanding properties.
We turn challenging slopes into refined outdoor living — caissons, retaining walls, pools, hardscape, and integrated landscape, engineered end-to-end by one team.
One integrated team. Architecture, hardscape, landscape, and outdoor living.
Most slope work fails because it's handed off between trades. At Vitoli Builders, the engineers who stabilize the hill are part of the same team that designs the patio, the pool, and the planting. The result: cohesive environments that hold up to the land, the weather, and the way you actually use the yard.
Three disciplines, one design-build studio.
From the foundation up — slope engineering, then the outdoor living layer, then the planting and finishing details that tie it all together.
Hillside Engineering
Caissons, retaining walls, slope stabilization, drainage. The structural backbone of every hillside project.

Outdoor Living
Resort-level pools, terraces, patios, and entertaining spaces — designed for the way Californians live outside.
Outdoor Living
Landscape & Garden
Hillside landscaping, native and drought-tolerant planting design, garden walls, and finish carpentry.
Landscape & GardenBefore us: an eroded, unusable slope. After: a multi-tiered landscape you actually live on.
A typical Vitoli hillside starts as a steep, patchy incline with poor drainage and no clear footing. We design and build the terracing, the retaining walls, and the planting in one continuous process — stabilizing the hill, gaining usable square footage, and turning what was once neglected ground into the most loved part of the property.
- Engineered foundations — caissons, footings, and drainage sized to the soil report.
- Terraced retaining walls in stone, concrete, or block to match the architecture.
- Erosion-controlled planting with native and Mediterranean species.
- Integrated lighting, irrigation, and finishing details — one team, one timeline.
Properties where the land is part of the challenge.
We've spent years on Southern California's harder lots — hillside homes, estate remodels, and luxury new builds. If your property is straightforward, you may not need us. If it isn't, you do.
Hillside Homeowners
Reclaim the slope. Add usable yard, view decks, and a structurally sound landscape that lasts.
Hillside Homeowners
Luxury Residential
Estate-grade design-build — pools, hardscape, masonry, and planting for high-value Southern California homes.
Luxury Residential
Estate Remodels
Re-engineer aging hardscape, replace failed retaining walls, modernize pool decks, and restore the original architectural intent.
Estate RemodelsBuilt for the parts of Southern California other contractors won't touch.
Hillside expertise, not hillside guesswork
Caisson foundations, engineered retaining systems, and slope analysis are core competencies — not subcontracted afterthoughts.
One team, one timeline
Architecture, masonry, pool, and planting under one contract — no GC handoffs, no schedule gaps.
Engineered drainage
Every hillside design is paired with a drainage plan sized to local rainfall and soil percolation.
Materials chosen for the land
Stone, concrete, decomposed granite, and planting palettes that hold up to Santa Ana winds, drought, and Mediterranean climate cycles.
Calabasas-local
Headquartered on Calabasas Road, we work the canyons, the foothills, and the estate corridors we drive every day.
I don't really even know how to describe the transformation to our yard — I don't think that I could have, in my head, imagined how much better it would look after Rob worked his magic.
From the first site walk to the final planting.
Site walk & scope
We meet on the property, read the slope, and map the constraints — drainage, access, setbacks, views.
Design & engineering
Architectural drawings, structural detail for retaining and caisson work, and a finish schedule for materials and planting.
Construction
One crew, one timeline. Foundations and hardscape first, then pool and finish trades, then planting and irrigation.
Handover & care
Walk-through with care instructions, irrigation schedule, and a seasonal punch list so the work matures the way it should.
Bring us the difficult property.
If your lot needs an engineer and a designer — and a builder who can do both — let's talk.
Walk the property with us.
Tell us a little about the lot — we'll set up a site walk, look at the slope, and tell you what's actually possible. No pressure, no upsell.
