Engineering for homes where nothing is standard.
With 25+ years of experience, we deliver coordinated, permit-ready engineering solutions for homes where nothing is standard. From full Mechanical, Electrical, Plumbing, Fire Alarm, Fire Sprinkler (MEPFS) solutions to partial scopes. We navigate complex constraints and code challenges with clear options, defined tradeoffs, and cost visibility.
Our involvement does not end at permit. Through plan check and construction, you continue working directly with the partners and receive fast, informed responses when questions, changes, or site conditions arise.
Based in Los Angeles and Newport Beach • Licensed in 20+ states
Are rigid engineering, slow revisions, and limited construction support creating costly delays on your residential project?
We help avoid:
-
Limited flexibility when design intent, site constraints, and cost all need to be balanced
-
Slow response to client-driven changes, causing redraws, re-coordination, and schedule drift
-
Permit-only involvement that leaves construction questions, substitutions, and field conditions unresolved


The NEECO & Arakelian Mission
William and Miro founded NEECO & Arakelian to deliver the level of engineering partnership high-end residential projects demand: hands-on partner involvement, clear accountability, and responsive support from early coordination through construction and turnover.
For architects, interior designers, builders, and homeowners, the result is fast resolution when field conditions shift, with close coordination around custom layouts and architectural details.
