Expand your living space with a seamlessly integrated addition including complete electrical service, HVAC rough-in, and smart home pre-wiring.
Adding space to your home is exciting, but it comes with significant complexity. A new room or addition needs its own electrical service, HVAC integration, proper insulation, and seamless connection to your existing home's systems. Most homeowners hire a general contractor who then subcontracts the electrical work, HVAC, and other specialized trades - creating a coordination nightmare.
Our integrated approach changes everything. As both a licensed General Contractor and licensed Electrician with extensive experience in home additions, we handle the entire project from foundation to finish. We design the electrical system alongside the structure, ensure HVAC is properly sized and integrated, and pre-wire for smart home features that match your existing setup.
The result? Your addition feels like it was always part of your home. The electrical integrates perfectly with your main panel, the HVAC balances properly with your existing system, and all the finishes match seamlessly. No finger-pointing between contractors, no scheduling conflicts, no surprises.
Whether you're adding a master suite, expanding your kitchen, creating a home office, or building a family room, we handle every aspect with the expertise that comes from being licensed in both construction and electrical work.
The biggest mistakes in home additions happen when systems aren't properly integrated. Here's what sets our approach apart:
We calculate total electrical load BEFORE construction starts. If your existing 100A panel can't handle the addition, we upgrade it during the project - not after walls are closed up. This saves thousands in retrofit costs.
Your existing HVAC might not handle additional square footage. We calculate heating/cooling loads and either extend your current system or add a mini-split. We rough-in during framing, not after drywall.
If your existing home has smart switches or automation, we match the system in your addition. All wiring is done during construction for clean, professional integration without surface-mount conduit.
We match existing finishes, flooring transitions, and trim details so your addition looks original to the house. Our construction experience ensures proper integration at every level.

We evaluate your property, check setback requirements, assess foundation conditions, and design an addition that complements your home's architecture. Electrical load calculations ensure your panel can handle the new space.
Structural engineering ensures your addition is safe and compliant. We prepare comprehensive plans showing construction details, electrical layouts, and HVAC integration. We handle all permit applications and approvals.
We pour the foundation, frame the structure, and tie into your existing home's framing. During this phase, we rough-in all electrical, ensuring outlets, switches, and fixtures are perfectly placed before walls are closed.
HVAC ductwork is installed and connected, electrical circuits are tied into your panel (or new subpanel), and all rough-in work is inspected. This is when we verify everything integrates properly with existing systems.
Drywall, paint, flooring, trim, and all finish work is completed. Electrical trim-out includes installing all switches, outlets, light fixtures, and smart home devices. Everything is tested and verified.
We coordinate final building and electrical inspections. Once approved, we do a comprehensive walkthrough showing you all new systems, smart controls, and maintenance requirements. You receive all documentation and permits.
*Timeline varies based on addition size, complexity, and permit approval times.
