Cost Per Square Foot: What You Need to Know When Building a Home in Knoxville

If you’ve ever looked into building a home, you’ve likely heard the term “cost per square foot.” A simple Google search will tell you that the average cost per square foot for new home construction in Knoxville, TN, ranges from $255 to $450 per square foot—a pretty big spread. So what determines where your project will land on that scale?

The truth is, cost per square foot isn’t a one-size-fits-all number. It’s easy to assume that every square foot of your home costs the same, but that’s far from reality. In fact, some rooms cost significantly more per square foot than others.

Where Does the Money Go?

Some areas of your home are more expensive to build than others. Let’s break it down:

  • Kitchens and Bathrooms – These spaces are by far the most expensive per square foot because they require costly finishes, plumbing, cabinetry, countertops, and appliances.
  • Bedrooms, Living Rooms, and Dens – These spaces are generally much more affordable because they don’t require the same level of specialized materials or mechanical systems.
  • The “Box” – The core structure of your home (foundation, framing, roofing, and exterior walls) is relatively predictable in cost. The real variability happens inside.

You Have More Control Than You Think

The great news? You have more control over your home’s final cost than you might realize. Since expensive areas like kitchens and bathrooms drive up the per-square-foot price, strategic choices in these spaces can help you stay within your budget without sacrificing quality.

Here are a few things to consider:
✔️ Prioritize Where It Matters – Invest in quality materials where they make the biggest impact. Maybe that’s a statement kitchen island or a spa-like shower.
✔️ Balance High-End and Budget-Friendly Choices – Not every surface needs to be top-tier. Well-planned design can create a high-end look without the premium price tag.
✔️ Work with a Builder Who Gets It – A knowledgeable builder (like Kairos Construction Group) can help you make smart decisions to get the most value for your budget.
