More space, same address. Alpha Construction designs and builds home additions that integrate seamlessly with your existing home — veteran-owned, NARI award-winning, and photo-documented from the first call to the final walk-through.
A home addition is the biggest structural project most homeowners will ever take on — and the one where a disciplined builder matters most. Alpha Construction handles the full scope: design, permitting, foundation, framing, and every finish, all managed on one structured process with clear communication at every stage.
From a single room addition to an expanded main living area, we build additions across Austin and the surrounding metro that look and feel like they were always part of the house.
Every addition starts with how your family actually lives. These are the projects Austin homeowners bring to us most often:
In a market like Austin's, moving often means trading a neighborhood you love — your schools, your commute, your street — for a bigger mortgage somewhere else. A well-built addition lets a growing family stay put and shape the house around their life instead of starting over.
Austin lots come with real constraints: setbacks, impervious cover limits, trees worth protecting. That's where planning discipline pays off. We walk the property, talk through what your lot allows, and design an addition that makes the most of the space you already own.
The mark of a good addition is that nobody can tell where the old house ends and the new one begins. We carry that standard through the entire build — foundation and structural work tied correctly into the existing home, exterior lines and materials that continue the original design, and interior finishes matched from flooring to trim to paint.
From structural work through finish selections, every decision is made before work begins, so the addition reads as one home — not a project stapled to the side of one.
