Windrush Open Model Showcase - Siepmann Realty

The Siepmann Realty Difference

Exceptional Properties. Natural Surroundings.

As you look for a lot for your new home, it is important to explore all your options. More than the school district or proximity to amenities, we encourage you to evaluate what makes the neighborhood you choose truly unique. As the developer behind the most innovative properties and iconic neighborhoods in the area, we’re proud to build places where neighbors become friends and friends become family. We know that no two communities are the same, yet the principles and commitment to quality remain unchanged. These three concepts guide our land development process, and should guide your homesite selection as well:


Running with the dog, watching the kids play in the field behind the house, an evening under the stars on the patio. How do you enjoy peace and quiet? Each community has been designed to draw out the best in life … no matter what that means to you.

Watching the deer along the tree line at dusk, strolling the walking trails, or simply listening to the wind blow through prairie grass … those are the sights and sounds of conservation development. Embracing natural elements and ensuring wildlife and vegetation is protected for generations.

Pulling into your neighborhood 20 years after you first built your home or entertaining friends for the first time in your brand new home – that wow-factor is there. Attention to detail across all homes in a community, guided by good design principals that drive architectural value.

Our Roots in Southeast Wisconsin


The best memories are made in the best neighborhoods. Some of our own family memories date back over 75 years when our grandfather Paul Siepmann’s first subdivision became a reality. Since then, we’ve taken conservation development further than ever imagined. As the developer behind the most innovative properties and iconic neighborhoods in the area, we’re proud to build places where neighbors become friends and friends become family.
