From Blueprint to Keys.
Design & Planning
We work with your architect or our design partners to finalize plans, specs, and materials. Every decision is made before ground breaks — no surprises mid-build.
Permitting & Site Prep
We handle all permits, inspections, and site preparation. Grading, utilities, and foundation prep done right from day one.
Foundation & Framing
Engineered foundation poured to spec. Framing completed with precision — walls, roof structure, and rough-in openings exactly as designed.
Systems & Envelope
Mechanical, electrical, plumbing, insulation, and exterior envelope. All systems coordinated and inspected before walls close.
Interior Finishes
Flooring, cabinetry, countertops, tile, paint, trim, and fixtures. Builder-grade quality control on every finish detail.
Final Walkthrough & Keys
Punch list completed, final inspection passed, and a full walkthrough with you before we hand over the keys.
Why Onyx & Iron
One Contractor.
Every Phase.
Building a custom home means coordinating architects, engineers, framers, concrete crews, plumbers, electricians, and finish contractors. Most homeowners spend months managing that chaos. We eliminate it — one team, one point of contact, one accountable partner from start to finish.
