Additions Planning Guide

What Does an Addition Cost?

Every addition is unique, and your vision, materials, and home’s structure all play a role in determining cost. The best way to get a clearer idea of what your project will require is by thinking through the details now—and that’s exactly what this Planning Guide helps you do.

While costs vary, here’s a general idea of what different types of additions typically range:

• Single-Story Addition

  (e.g., expanding a kitchen, adding a family room)

  • $125,000 – $300,000+

• Two-Story Addition

  (adding bedrooms, bathrooms, or a second-floor living space)

  • $200,000 – $450,000+

• Sunroom or Screened Porch

  (enclosed spaces with natural light)

  • $80,000 – $200,000

• Kitchen Expansion or Breakfast Room

  • $140,000 – $250,000+

• Master Suite Addition

  (bedroom, bathroom, walk-in closet)

  • $200,000 – $350,000+

In addition to construction costs, furnishings, finishes, and energy efficiency upgrades can impact your overall investment. At KraftMaster Renovations, we design with the build in mind, ensuring that your addition integrates seamlessly into your home—both functionally and financially.
