Grow Without Moving

More room, in the home you love.

Outgrowing your house doesn’t have to mean leaving the neighborhood, the schools, and the yard you’ve put years into. A thoughtful addition gives you the space you need where you already are — and when it’s built right, you can’t tell where the original house ends and the new work begins.

What We Add

Single & multi-room additions

A new family room, a bigger kitchen, a main-floor bedroom — built onto your existing footprint.

Second-story additions

Double your living space without losing your yard — a full level up, engineered and permitted.

Primary-suite additions

A private master bedroom with a walk-in closet and a spa bath — a favorite for resale value.

Sunrooms & bump-outs

Covered patios, sunrooms, and bump-outs that bring light and breathing room to the main floor.

Why Red Umbrella

An addition is only as good as the seam.

Matched, seamless lines

We match the existing rooflines, siding, and trim so the addition reads as original, not bolted-on.

One accountable crew

Framing, electrical, and finish under one master craftsman — no juggling separate trades.

Energy-smart construction

Stick-frame or SIP, with a tight, well-insulated envelope that keeps the new space comfortable.

What it costs

Home addition pricing

Additions are priced by scope and square footage — a bump-out, a primary suite, and a full second story are very different projects. A free on-site consultation with Bari gives you an honest, specific number for your lot — no obligation.
