  • What types of home additions do you offer?

    We design and build a wide range of additions, including:


    • Room expansions (bedrooms, living rooms, etc.)
    • Second-story additions
    • Sunrooms and enclosed porches
    • In-law suites or guest quarters
    • Garage conversions and bonus rooms

    Each project is tailored to match your home’s style, structure, and your specific needs.

  • Will I need to move out during construction?

    Not always. Many additions can be completed while you remain in your home, especially if the work is isolated to one area. However, for major structural changes or second-story builds, temporary relocation may be recommended for safety and comfort.

  • Do I need permits for a home addition?

    Yes, most home additions require building permits to ensure compliance with local codes and zoning laws. We handle the permitting process for you, including:


    • Submitting plans to the city or county
    • Coordinating inspections
    • Ensuring all work meets safety and structural standards
