Why Additions Require The Right Contractor
Additions Are Complex.
Experience Matters.
Structural Engineering
Additions require proper foundation, framing, and connection to the existing structure. We work with licensed structural engineers on every addition project.
Permit & Inspection Management
Additions require multiple inspections: foundation, framing, rough plumbing, rough electrical, insulation, and final. We manage the entire permitting timeline so your project does not stall.
Exterior Matching
A good addition looks like it was always there. Our 3D design process shows you the exterior result before we build it, so the roofline, siding, and windows integrate cleanly.
HVAC Integration
Extending your HVAC system to a new addition requires a load calculation, possible equipment upgrade, and duct work. We coordinate your HVAC contractor as part of the project.
