Kick-the-can. Ghosts in the graveyard. Flashlight tag. The best childhood memories are made in the best neighborhoods. At Siepmann Realty, we’ve been developing subdivision communities and family memories since 1943. Our grandfather, Paul Siepmann, built the first Siepmann community on 80 acres of farmland in Brookfield, which was primarily sold to veterans returning from World War II. The tradition continued with our father, Ron who transformed the concept of Planned Unit Development (PUD), later called cluster developments, and now referred to as Conservation Subdivisions. Under our father’s leadership, Siepmann Realty Corporation became nationally known for this creative style of development. Since then, siblings Jim, John, and Karen, have taken conservation development further than ever imagined. Partnering with the Waukesha County Land Conservancy to protect our natural resources, and bringing architectural foresight to our development. We’ve set the standard for community amenities. 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. Residential land planning and neighborhood development has been our company’s focus since its inception. Over the years, our team has developed over 100 distinctive and award-winning neighborhoods such Tree Tops in Germantown, Hawksnest and Stillmeadow in Delafield, Steeplechase and Broken Hill in Pewaukee, and Preserve at Hunter’s Lake in Ottawa.

The 2000s
What is going on in the new millennium?
“Over the last 25 years we have built two homes in Siepmann Developments and most recently built a home on a private lot with Ascent Custom Homes. There are several words that come to mind when we think back on our experiences. The first is consistency. We found the same attention to detail, whether in the development of the subdivisions or in the building of our current house with Ascent. The second is communication. Our current house was built on a difficult lot and Ascent embraced the challenge. They made a extra effort to keep us up to date and aware of everything that was going on. The third is honesty. There was never a time in any of our endeavors that we didn’t have complete trust that they were being upfront with us. We highly recommend Siepmann Realty/Ascent Custom Homes and consider each of our experiences as very positive.”
“Siepmann developments bring “HOME” to a community. As a homeowner and a builder, I love to be part of a Siepmann community. The details they put into their subdivisions are second to none! We love the fact that Siepmann strives for the very best architectural standards, because homeowners alike are ensured that the home built next door to them will be of the same high-quality architectural caliber that you come to expect in all Siepmann subdivisions.”
“Using progressive design techniques, Siepmann Realty has achieved its development goals according to local ordinances, while creating much greener neighborhoods where residents can enjoy trails, woodlands, meadows, ponds, and much more. These park-like settings and environmental habitats have stood the test of time, maturing very beautifully and creating great places to live for many future generations to come.”
“In my long experience across the country, I believe that Siepmann Realty is absolutely unique among residential developers in terms of its deep commitment to, and continuing implementation of, its philosophy of conserving quality upland (not just the unbuildable areas) through the subdivision process. While some other firms state this kind of approach among their corporate goals, the leadership and staff at Siepmann Realty take this very seriously, as one of its core guiding principles. This is not idle talk and promises – the proof has been in the pudding, so to speak, with more than 1,700 acres permanently preserved as common open space over the past several decades — much of which would have been converted to suburban lawns by most other developers.”
“I have had many successful transactions with Siepmann Realty in my 27 years as a Realtor. I can always count on good communication, attention to detail on contracts, and great negotiating skills. Siepmann developments hold their value and are sought-after places to live. It is always a pleasure to sell a lot or a home in a Siepmann development.”
“When my wife and I were looking to build our “dream home,” we spent a lot of time looking at various properties and found Siepmann’s developments to be unmatched in the use and amount of open, natural spaces, and high-quality design and construction of common elements. If we were going to build our dream home, then we wanted it to be in our dream neighborhood, which we found with Siepmann. We loved that we could chose our own builder, and we wanted to avoid the “cookie cutter” look that we saw with other developers. Aside from the great layouts and abundance of open space, we chose Siepmann because of the great features they tend to include in their projects, such as paved walking trails, ponds, and clubhouse and community pool. Last, but not least, we wanted to protect our investment by building in a high-quality development, and Siepmann’s developments are recognized as some of the best in southeastern Wisconsin.”
A Creative & Artistic Approach to Land Planning
The Siepmann Difference
“How will it look when it’s done?” That’s a common question we are asked about our communities. Sometimes it can be hard to picture a neighborhood with roads, homes, landscaping, and maturing trees shortly after development. That’s why we invite you to ride-along with one of our team members through other Siepmann subdivisions…so that you can see and feel for yourself what a sense of community looks like when all the pieces come together.
