Design-Build for Homes & Development
Infill, ADUs & Modern Multifamily
Onyx General Construction blends architecture, construction, and quiet development insight into a unified design-build process. From ADUs and fourplexes to small multifamily infill projects, we focus on thoughtful site use, zoning-aware planning, and precise execution that fits the fabric of Los Angeles neighborhoods.
A Modern, Development-Aware Approach
Onyx General Construction blends high-end design-build capability with a quietly integrated understanding of small-scale development. Our work extends beyond residential renovations into thoughtful solutions for ADUs, duplexes, fourplexes, and infill opportunities throughout Los Angeles.
With an emphasis on clarity, feasibility, and architectural restraint, we help shape projects that feel purposeful and well-considered—aligned with the evolving fabric of the city and the people who live within it.
Integrated Build & Development Insight
At Onyx, our design-build approach naturally extends into small-scale development. We understand the nuances of infill lots, ADUs, and compact multifamily sites—how layout, zoning, and feasibility quietly shape long-term value.
From fourplex configurations to strategic additions, our team blends architectural clarity with practical construction insight—helping homeowners and investors unlock the full potential of their properties.
Urban Development with a Grounded Perspective
Our experience in design-build construction gives us a grounded perspective on urban development. Whether it’s an ADU, a four-unit building, or a modest multifamily concept, we focus on thoughtful site use, efficient planning, and refined execution.
Onyx approaches each project with the same intent: create structures that feel considered, durable, and well-integrated into the fabric of Los Angeles neighborhoods.
Quiet Capability in Urban Development
Beyond residential remodels and additions, Onyx supports clients exploring development at the smaller scale—ADUs, duplexes, fourplexes, and infill lots tucked within established communities.
We bring design discipline, permitting knowledge, and construction precision to projects where every square foot matters. The result is a balanced, understated approach to building and development in Los Angeles.
