If the story of Newark’s revitalization is all about buildings, Hall, a 60-year-old principal at a charter school here, is living inside one of its newest characters. Her eclectic, fifth-floor apartment is one of the residential units in Teachers Village, a $150 million, mixed-use project financed through a consortium of private and public investments and blessed with mammoth government tax credits. The development lives along five blocks of Halsey Street, just off of the city’s main thoroughfare and was designed to convert into residents some of the 6,000 teachers and administrators who commute to this city of 280,000 each workday.
