Residential Building

The Sigma Group was retained by HSI Properties to provide professional civil engineering and survey services for the State Street Station development. State Street Station is a two-acre mixed-use community located at 7400 West State Street. At the heart of Wauwatosa Village, the building stands four stories tall with 148 luxury units, and 25,000 square feet of ground floor retail. The project includes high-end unit amenities, heated underground public parking, and state-of-the-art common areas.

A key element of the project was coordination with the City of Wauwatosa. Sigma was asked to design the utilities and streetscape that tied into the existing street conditions, while taking into consideration future road work that the city has planned for streets surrounding State Street Station.
