Activity is picking up at The Davenport, a 109-year-old apartment building in Midtown that was vacant for years. Announced late last year, the restoration project was limited to boring utility work over the winter. These days, the building is teeming with workers clearing junk and gutting the interior, which will be rebuilt as eight apartments of affordable housing. The Davenport expects to be ready in October, but don't forget to keep an eye on its larger neighbor, Cass Plaza. That effort should begin showing similar signs of life any day.
