Love Your Neighborhood? Add On Instead of Moving

In Winona, the math on moving often doesn't work: housing inventory is tight, the neighborhoods people love — near the lake, the river, the schools — rarely have listings, and giving up a location you love for one more bedroom is a bad trade. An addition lets you keep the street and gain the space. We've been building them here since 1987.

Winona additions come with Winona challenges: tight East End and downtown lots where setbacks decide the design, older foundations that need evaluation before anything bears on them, and the trickiest part of any addition — making the new part look like it was always there. Matching rooflines, siding profiles, window styles, and trim is where 39 years of experience shows.

Josh and Justin manage every addition personally, from the first sketch through city permits, weather-tight shell, and finished interior. And because we self-perform the framing and finish work, your addition isn't handed between subcontractors who never talk to each other.

Designed to Disappear

The best compliment an addition gets is nobody realizing it's one. We match foundation lines, roof pitches, siding reveals, and window proportions so the finished home reads as one house — not a house with a box attached.

Winona Addition FAQ

How much does a home addition cost in Winona?
Most room additions in the Winona area run $150–$300 per square foot depending on complexity — a 300 sq ft family room addition typically lands between $60,000 and $90,000, while additions with kitchens or baths run higher. Our Minnesota addition cost guide has detailed numbers, and estimates are always free and written.
How long does an addition take?
Most room additions run 6–12 weeks from groundbreaking; second stories and larger projects run longer. We get the shell weather-tight as fast as possible so your existing home stays protected, and we give you a written timeline before we start.
Can you add on to a house on a small city lot?
Usually, yes — it just takes design work up front. We check City of Winona setbacks and lot coverage rules before drawing anything, and when the lot won't allow building out, we look up: second-story additions solve most tight-lot problems.
Will the addition match my existing house?
That's the job. We match roof pitch, siding profile and color, window style, trim, and interior floor heights so the transition is seamless inside and out. On older homes we source period-appropriate materials — it's the difference between an addition and an add-on.
