The groundbreaking was just held in July of 2023, at which time the developer, Neighborhood Development Company stated, “The project is truly green, with construction being completed with environmentally conscious technologies as well as offering the opportunity for eventual occupants to realize significant savings in utility costs and minimize their carbon footprint” ( The 4-story building has a partial concrete podium over ground-floor parking.
