Adding a second story to a ranch house requires collaboration among architects, structural engineers, contractors, and building professionals. Architects design the addition and ensure its design integrity, while engineers assess structural feasibility. General contractors coordinate the project, while specialized contractors handle tasks like framing, roofing, and window installation. Building professionals improve comfort and efficiency through interior design, HVAC, electrical work, and insulation. The Zoning Board ensures compliance with local ordinances, protecting community integrity.
