425 Grand Concourse is the largest Passive House (PHIUS) project in North America to date. This new mixed-use and mixed-income development create 277 units of affordable housing. The two-story base houses a medical facility, supermarket, community support space, and a new student services center for CUNY Hostos—each also designed by Dattner Architects.

The building offers residents a wide variety of amenities including a recreation room, landscaped roof terrace, a lounge space and fitness room, laundry rooms, and bike storage.

This benchmark sustainable project provides a model for healthy living environments in a district with one of the worst childhood asthma rates in the country. Each apartment’s living room and bedrooms directly receive filtered, ventilated air, increasing interior comfort and air quality. The project’s expansive windows provide abundant amounts of daylight into the apartments while balancing the window-to-wall ratio that is critical to achieving Passive House performance levels.

The project balances the critical need for affordable homes and the need for a high-quality and attractive development that promotes street activity. As a gateway to the Bronx’s historic Grand Concourse, one of the Bronx’s great boulevards, the new development anchors this important corner and enhances the Mott Haven neighborhood.
