More room, right where you need it.
Room additions, second-story builds, in-law suites, and full-wing expansions across the Ohio Valley — engineered, permitted, and finished by one team.
Grow into the home you already love.
Selling and moving is expensive, disruptive, and rarely gets you exactly what you want. A well-planned home addition adds the space you actually need — an extra bedroom, a bigger kitchen, a first-floor primary suite, a home office, an in-law suite — while keeping the location, neighbors, and memories you already have.
Steel Valley handles design, engineering, permits, foundation, framing, mechanicals, and finish work under one project manager. Your addition matches your existing home in siding, trim, and rooflines so the finished house reads as one.

Frequently asked questions
How long does a home addition take?
Most single-room additions run 3–5 months; larger second-story or wing additions run 5–8 months. Timelines depend on permits, engineering, and structural scope — we commit to dates at contract signing.
Do you handle architecture and engineering?
Yes. We work with local architects and licensed structural engineers to produce stamped plans for your permit and your project. You get one team from concept to close-out.
Will you match my existing house?
Yes — siding, trim, rooflines, and interior finishes are matched to the existing home so the addition reads as original. Where matching isn't possible, we design a clean architectural transition.
Can additions be financed?
Yes. Larger additions are often paired with construction loans or home equity financing. Through Hearth you can pre-qualify for smaller phase-based projects in minutes.
