Frequently Asked Questions
How do you match the new addition to my existing home?
We carefully source matching or complementary materials including roofing, siding, windows, and trim. Our designers study your home's architectural style to ensure rooflines, proportions, and details blend seamlessly. When exact matches aren't available, we design transitions that look intentional and enhance your home's overall appearance.
Do I need to move out during construction?
Usually not. We carefully plan construction phases to maintain livable conditions in your existing home. We create weather-tight barriers before opening any walls, manage dust and debris, and schedule noisy work during reasonable hours. Most families stay in their homes throughout addition construction.
What permits are required for a home addition in Florida?
Home additions require building permits including structural, electrical, plumbing, and mechanical permits. In flood zones, additional documentation may be required. We handle all permitting as part of our service, including plan preparation, submission, and coordination of all inspections throughout construction.
How much does a home addition cost in Northeast Florida?
Home addition costs typically range from $200-$400 per square foot depending on complexity and finishes. A basic Florida room might cost $50,000-$80,000, a master suite addition $100,000-$200,000, and second story additions $200,000+. We provide detailed estimates after our feasibility study.
How long does a home addition take to build?
Timeline depends on size and complexity. A simple Florida room might take 2-3 months, a master suite addition 3-5 months, and a second story addition 5-8 months. Permitting can add 4-8 weeks before construction begins. We provide a detailed schedule during the planning phase.
