Sierra Development, owned by Manuel Carrillo, handles residential, commercial, remodeling, and sitework construction. Serving Santa Clarita, Castaic, the entire San Fernando Valley, the San Gabriel Valley, and Los Angeles. We also serve Malibu, Beverly Hills, Bel-Air, Pacific Palisades, Brentwood, Santa Monica, Topanga, and surrounding Los Angeles communities.
From a hillside retaining wall to a municipal infrastructure contract, we self-manage the trades so nothing falls through the cracks.
We handle pre-construction, permitting, sitework, structural trades, and finishes under one roof — residential, commercial, or municipal.
Patios, pools, outdoor kitchens, and planted landscapes designed and built as one cohesive outdoor space.
Pile drilling, caissons, and foundation work engineered for steep, difficult terrain across LA's hillside neighborhoods.
Engineered walls built to last — from decorative garden walls to load-bearing structural retention.
Custom pools, spas, and infinity-edge designs — including complex hillside pool construction.
Safe, efficient sitework and demolition for projects of any size, residential or commercial.
Ground-up construction and tenant improvements for offices, retail, and mixed-use buildings.
Public infrastructure and municipal projects delivered with the permitting and compliance experience they require.
Electrical work for new construction and renovations, integrated with the rest of your build.
From preconstruction planning and site preparation through foundations, building systems, custom finishes, and final handover, Sierra Development coordinates the complete construction scope. Discuss custom homes, additions, ADUs and garage conversions, kitchens, bathrooms, whole-home renovation, concrete, excavation, drainage, outdoor living, exterior renovation, and interior finishes alongside our established structural, commercial, and outdoor services.
Every project moves through the same disciplined process, whether it's a backyard or a public works contract.
Budgets, schedules, and pre-construction clarity before a single shovel hits the ground.
Site coordination, safety oversight, and daily progress — with weekly updates and photos so you always know where things stand.
Craftsmanship, inspections, punch lists, and a clean handoff — on the terms we agreed to at the start.
Real jobsite photos, pile drilling, retaining wall construction, and the finished outdoor spaces they made possible. Explore the hillside pool and retaining wall project.
Video from active jobsites, plus reference reels showing the finish quality we build toward. Footage is ambient — no dialogue.

Zero excuses on timelines — we plan for the terrain and the trades before we ever break ground.

We coordinate directly with architects and owners so the finished build matches what was drawn.
Whether it's a family backyard or a municipal contract, the same coordination discipline applies.
Access, staging, and site logistics planned to minimize disruption around the jobsite.
