Professional Home Additions in La Crosse, WI—KO Construction

Why Build an Addition Instead of Moving?

Moving can be a major headache—not to mention expensive and emotional. When you love your neighborhood, have built memories in your home, and enjoy the benefit of a low mortgage interest rate, why uproot everything?

Building onto your existing home is a smart and practical solution.

It allows you to:

• Stay in the neighborhood and school district you love
• Avoid the stress of house hunting and moving costs
• Keep your current mortgage and interest rate
• Customize your space to fit your exact needs

With KO Construction, you don’t have to compromise. You get the extra room you need, with the quality you deserve—right where you are.
