Add Space Without Moving

Love your neighborhood but need more room? A home addition might be the perfect solution. Instead of going through the hassle and expense of moving, you can add the space you need right where you are. At Realtree Construction, we help Nashville homeowners expand their homes with additions that look like they were always part of the original design.

Whether you need an extra bedroom, bigger kitchen, home office, or expanded living space, we handle every detail from design to final walkthrough. We've been building home additions across Middle Tennessee for years, and we know how to do it right.

Why Build a Home Addition?

• Stay in Your Neighborhood

  You love where you live. Your kids are settled in school. You know your neighbors. Why leave if you don't have to?

• Avoid Moving Costs

  Moving is expensive and stressful. Realtor fees, closing costs, moving trucks, time off work – it all adds up fast.

• Get Exactly What You Want

  With an addition, you design the space to fit your exact needs. No compromising on someone else's floor plan.

• Increase Home Value

  A well-designed addition adds significant value to your Nashville home. You're investing in your property.

• More Affordable Than You Think

  Depending on what you need, an addition can cost less than buying a bigger house in your neighborhood.
