Thinking about expanding your home? Whether you're looking to add more space, increase your home’s value, or create a more functional living area, a home addition is a great investment. However, before you dive in, it’s important to understand the costs involved. At Kolby Construction, we specialize in high-quality home additions in Charlotte, NC, and we’re here to break down what you can expect when planning your project.
Factors That Affect Home Addition Costs:
The cost of a home addition varies depending on several key factors, including
✔ Size & Complexity – Larger and more intricate designs cost more.
✔ Materials Used – Standard vs. high-end finishes significantly impact pricing.
✔ Labor & Permits – Skilled professionals and required permits add to overall costs.
✔ Location – Prices for labor and materials differ based on local market rates.
On average, home additions in Charlotte range from $125,000 to $250,000, with high-end projects exceeding $250,000.
Cost Per Square Foot
Home additions typically cost between $350 to $500 per square foot. This price includes everything from design and materials to labor. For example, adding a 20' x 18' room addition could cost anywhere from $125,000 to $200,000, depending on finishes and complexity.
Building Up vs. Building Out
When adding space to your home, you can either build up (add a second story) or build out (extend your home’s footprint).
✔ Building Up – Typically more cost-effective, as it avoids foundation work.
✔ Building Out – Offers more flexibility but may require excavation and additional site prep.
Each option has its advantages, and our team at Kolby Construction can help determine the best solution for your home.
