Home Addition Contractor
in Anderson, IN.
We build home additions in Anderson, IN — room additions, second stories, in-law suites, and bump-outs that fit the home you already have. Anderson is the seat of Madison County, and we build new homes, additions, and renovations across Edgewood and the corridors east of I-69 — close enough to be home for projects without sacrificing on-site presence. Most additions in Madison County involve careful work with existing structure, foundations, and rooflines, and that's where the difference between a good builder and a careful one shows up.

How we approach home additions in Anderson.
Every home additions project we run in Anderson follows the same proven process — from the first site visit to the final walk-through.
- 01
Room additions
Family rooms, primary suites, and home offices that match the original home in scale, finish, and feel.
- 02
Second-story additions
Doubling your footprint without losing your yard. We engineer the load path and protect what's below.
- 03
In-law / accessory suites
Private suites for parents, adult children, or guests — code-compliant and designed for long-term use.
- 04
Bump-outs & dormers
Smaller-scale additions that solve a specific problem (a bigger kitchen, a real mudroom) without overhauling the home.
- 05
Garage additions
Attached and detached garages, sometimes with finished space above. Sized and finished to match the home.
- 06
Permits & engineering
We handle the structural engineer, permits, and inspections — and we work clean so the existing home stays livable through the build.

How much does a home addition cost in Anderson, IN?
Most home additions in Anderson and Madison County fall between $200–$400 per square foot, depending on whether you're adding to the foundation, going up a story, or extending mechanicals. We give you a detailed estimate after a site visit so the number reflects your actual home — not an industry average.
Can we live in the home during the addition?
In most cases, yes. We zone the work, dust-protect the existing home, and sequence the cut-ins to keep things livable. For larger jobs (whole-floor additions, kitchen + addition combos), we'll talk through whether a short-term move makes sense.
How long does a typical addition take?
Smaller additions (300–500 sq ft) usually run 3–5 months once permits are in. Second-story or whole-wing additions are typically 6–9 months. Design and engineering can add 2–4 months on the front end depending on scope.
Do you handle the architect and engineering?
Yes. We work with trusted architects and structural engineers across Central Indiana, or we'll work alongside yours. For most additions we recommend involving us early so the budget and structural approach line up before drawings get expensive to change.
