Sage on Prospect is an apartment building on Milwaukee’s Lower East Side. The project features a conversion of a 1961-built senior-living facility, with one floor removed and two added.

The project is being developed by Dominion Properties LLC as their second property to feature their Sage brand.

The project was designed by Joel Agacki of Striegel-Agacki Studio.

When completed, the project is expected to include 34 apartments.

In May 2015, Dominion began drilling for geothermal wells underneath the parking lot on the north side of the 18,184 sq-ft lot.
