Home Additions in Waco, TX

When your family outgrows your home, moving isn't the only option. A well-built addition gives you the space you need in the neighborhood you already love — often for less than the cost of buying and relocating.

Grace Custom Contracting & Design has been building additions for Waco and Central Texas homeowners since 2014. We handle the whole project: design, permits, foundation, framing, and finish work, all under one contract.

Types Of Additions We Build

  • Room additions — bedrooms, home offices, sunrooms, and expanded living areas built to match your existing structure
  • Second-story additions — added square footage without giving up yard space
  • Restaurant build-outs
  • Accessible additions — ground-floor suites, widened doorways, roll-in showers, and step-free entries
  • Garage conversions and expansions
  • In-law and guest suites


Accessible & VA-Funded Additions

Not every contractor will take on a grant-funded accessibility project. The paperwork is demanding and the build specifications are strict.

We do.

We've completed VA grant-funded accessible additions for Waco-area veterans, coordinating with program requirements from application through final inspection. If you're working with a Specially Adapted Housing grant, a HISA grant, or another accessibility program, we can walk you through what's involved.


Areas we serve


Waco, Hewitt, Lorena, Woodway, Robinson, China Spring, McGregor, and surrounding Central Texas communities.

Addition Costs in Waco

Every addition is priced on its own scope, but the variables that move the number most are:

  • Square footage and complexity — a simple bedroom addition costs far less per foot than a second story requiring structural reinforcement
  • Foundation work — Central Texas soil conditions often require engineered foundation solutions
  • Utilities — extending HVAC, plumbing, and electrical to new space
  • Finish level — standard versus custom cabinetry, flooring, and fixtures
  • Permits and inspections


Our Process

  1. Consultation — we visit your home, discuss what you need, and assess what's structurally possible.
  2. Design — plans that integrate with your existing home rather than looking bolted on.
  3. Permits — we handle City of Waco and county permitting.
  4. Construction.
  5. Final walkthrough — we don't consider it finished until you do.
