Custom home construction in Los Angeles
A custom home starts with the property, not just a floor plan. Sierra Development handles general construction for new residential projects in Los Angeles and the surrounding valleys, bringing sitework, structural construction, building systems, and finish work into one coordinated scope. Manuel Carrillo is the owner and your contact for discussing the property, available plans, and the build you want to pursue.
Build a scope that fits the site
A flat parcel and a hillside lot create different construction questions. Access, material delivery, excavation, drainage, foundation design, utility connections, and protection of neighboring property all need attention before the construction sequence is finalized. Share the parcel address and any survey, geotechnical report, or architectural and engineering drawings already prepared. We can discuss what information is still needed for a construction proposal.
The plans should also explain how the house will be used. Bedroom layouts, indoor-outdoor connections, garage needs, accessibility goals, storage, and future flexibility affect more than appearance. Discuss these decisions before assemblies and materials are ordered so the proposed scope reflects how you intend to live in the home.
Coordinate the structure and the finish
Foundations, framing, roofing, windows, weather protection, plumbing, electrical, and mechanical systems need to be sequenced before interior finishes. A construction proposal should distinguish the work shown on the plans from allowances, owner selections, and items not yet defined. Cabinets, stone, tile, fixtures, and doors can have different purchasing lead times, so selections should be tied to the construction schedule rather than left until installation.
For hillside construction, review our foundation and pile-drilling services and documented retaining-wall project. Those photographs show actual sitework and outdoor construction; they are not a claim that every proposed home has the same engineering requirements.
Start with a project review
Tell Manuel whether you own the property, have a design team, or are still comparing the feasibility of a new build with a major renovation. Include the desired floor area, intended uses, target investment range, and current permit status. Construction pricing and scheduling depend on the plans, site conditions, approvals, and material selections; a generic square-foot estimate is not a substitute for reviewing the actual project.

Discuss bespoke new homes, additions, whole-home remodeling, hillside construction, pools, and connected sitework with Manuel Carrillo. For a ground-up build, share the property location, available plans, design and permit status, and desired finishes so the entire construction scope can be reviewed from beginning to end.
Questions before you build
Does Sierra Development discuss custom homes & new construction in the surrounding valleys?
Yes. Sierra Development serves Los Angeles, Santa Clarita, Castaic, the entire San Fernando Valley, and the San Gabriel Valley. Send the property location and scope to Manuel Carrillo for project review.
What should I provide for a custom homes & new construction inquiry?
Send the project address or neighborhood, current photographs, available drawings, intended work, and known access or occupancy constraints. Identify design and permit information still pending. A price or schedule depends on reviewing the actual scope.
