About Loos Homes
Loos Custom Homes is a family-oriented homebuilder based in Johnson Creek, Wisconsin, founded by Greg Loos in 1997. With a background in carpentry and a commitment to quality craftsmanship, Greg built the company on the belief that homes are more than just structures—they’re places where families grow and memories are made. Over the years, Loos Homes has become known for building dozens of homes annually across Southeastern Wisconsin, between Milwaukee and Madison, with a focus on transparency, integrity, and personalized service.
The company prides itself on its straightforward pricing, strong customer relationships, and a responsive team that guides clients through every step of the building process.
