What does a home addition cost?
Home additions are the most significant projects we build and you deserve a straight answer before you ever pick up the phone.
Starting around $150,000
Sunrooms, 3-season rooms, and mudroom bump-outs. Beautifully designed and fully integrated with your home.
$400,000+
Primary suite additions, in-law suites, kitchen expansions, 2nd-story additions and large-scale whole-home transformations.
Here’s what drives the investment:
☑️ Structural & Exterior Work: Foundation, framing, roofline integration, siding, windows and doors all have to match or improve what’s already there.
☑️ Design Selections: Adding square footage that looks and feels like it was always there with cabinetry, trim, flooring and lighting that integrates seamlessly is our specialty.
☑️ In-house Architecture & Design: Unlike many contractors, we handle design, architecture, and engineering under one roof. That expertise is built into your project from day one not billed separately when surprises come up.
☑️ Permits & Municipality Coordination: Wisconsin additions require careful navigation of local codes and inspection timelines. We manage all of it.

Why an Addition?
When you love your home’s location and don’t want to move, an addition is the solution. Whether you have a growing family or want to modernize the layout, the Kowalske team will work with you every step of the way. We have worked with many homeowners to reconfigure their main floor living area. Convert a small bathroom to a spacious luxury bathroom. Add a sunroom, mudroom, home office, or expand your kitchen for entertaining.
Home Addition Challenges
The Kowalske team works with you from planning to building. We have a team of in-house professionals to guide you every step of the way, from design to architecture to finish carpentry. Home additions require exterior work and you can count on Kowalske for siding, doors, windows, garage doors, porches, decks and roofing. With so many options, the possibilities for your home addition are unlimited.
Design Considerations
The Kowalske remodeling team specializes in adding aging-in-place features. A home addition can create a space that better works for your family. You may need a zero entry shower, a more spacious kitchen, or a mother-in-law suite addition. Or maybe your parents plan to move in with you and your home is not accessible. Most homeowners hope to live in the comfort of their own home well into retirement.

What Our Customers Are Saying
“Their team delivered impeccable customer service, craftsmanship, and clear communication throughout the project.
The entire staff was not only professional but also friendly, making the process enjoyable and their user-friendly app kept us well-informed and organized.
Our designer was outstanding, turning our vision into reality. Kowalske transformed our master bath, family room, kitchen, and added a beautiful sunroom. Our head carpenter was warm, efficient and looked after the project like it was his own home.”
– Lauren (Mequon)
“My home is “unique” and presented many challenges. The lead designer I worked with was amazing. She very quickly got a sense of my style and wishes and I was blown away by the design ideas presented to me.
The online software (Buildertrend) was very easy to use, was consistently updated, and allowed me to view updates to the schedule, keep track of billing & payments, and to communicate with members of the team. I have a few additional projects in mind and will most likely use Kowalske K&B.”
– Michelle (Dousman)
