Permits have been filed for a 37-story, 384-unit tower in East Harlem as part of Sendero Verde, a massive mixed-use complex developed by Jonathan Rose Companies and L + M Development. The site’s newest building is set to rise at 1681 Madison Avenue and measure just over 385,000 square feet. Floors five through 36 of the Handel Architects-designed building will contain 12 apartments each; offices and retail space will occupy the first three levels, as CityRealty learned. A fresh pair of renderings of Sendero Verde highlights the winding central landscaped path, nonprofit DREAM’s charter school and the extensive community space planned for the development.
