Our Room Addition Process in Coachella
Every room addition in Coachella follows the same proven process we have refined over 17 years of Coachella Valley construction. Here is exactly what to expect when you hire Niem Construction.
Feasibility Assessment & Design
We evaluate your lot, existing structure, setback requirements, and zoning rules, then create architectural plans for your addition that integrate seamlessly with your home's existing design.
Permit Application & Engineering
We submit plans to the local building department, coordinate engineering reviews, and secure all required permits before construction begins.
Foundation & Framing
New foundation is poured to match your existing structure, framing goes up, and the addition is tied into your home's roof line, electrical panel, and plumbing system.
Electrical, Plumbing & HVAC
All mechanical systems are roughed in, inspected, and connected to your home's existing infrastructure. Desert-rated HVAC systems are sized to handle the added square footage.
Interior Finish & Final Walkthrough
Drywall, flooring, paint, trim, fixtures, and finishes are installed. We match the addition's interior style to your existing home so the new space feels like it was always there.
