In 1842, a sawmill with an adjoining home was built on Lake Nagawicka; about 45 minutes west of Milwaukee. By today’s standards, its nineteenth-century style — featuring natural stone and brick with rustic wooden beams — would be considered a charming addition to any neighborhood.

Unfortunately, time had taken its toll on many of the home’s critical structural components. The Mill Street home’s developer saw an opportunity to reclaim and revitalize its special character by putting Spancrete the heart of the new, sustainable structure.

Using a wide variety of precast solutions helped preserve the integrity of this historic home for generations to come.

Spancrete precast products help the home obtain optimal energy efficiency. The first and second floors, as well as the garage, are built with hydronic piping in the precast floors to heat the home. Hydronic piping is a thin and flexible tubing that runs through precast panels and connects to a home’s standard boiler. The concrete is heated, like a heating pad, and retains that heat, slowly releasing it over time, keeping the whole environment warm in the process. That delivers a staggering amount of energy efficiency, reducing heating consumption and cost.

The home’s driveway and sidewalks also offer environmental benefits, as they are made from Spancrete RePlenish pervious concrete, which creates additional drainage to help prevent flooding and direct water flow to restore water supplies. It can withstand up to 500 inches of rain an hour, allowing water to naturally flow into the earth. It also will withstand freeze and thawing.

The completed home combines stunning, rustic aesthetics with modern features, fits perfectly into its surroundings and delivers the sustainability homeowners seek in new construction. Mill Street is proof of the benefits and versatility of Spancrete precast components for new home construction.
