At the same time the old building is coming down, the 139-unit new Capper Building #2 at 400 M Street is going to be opening its doors to residents. Originally designed as a building for low-income seniors, its profile has been expanded to also include renters who earn up to 60 percent of the area median income (from $38,000 for one person to $54,000 for a family of four). I was given a tour yesterday and got photos of the inside; the first floor has a community room with kitchenette, and laundry, computer, fitness, and conference rooms, and the landscaped interior courtyard also serves as a stormwater management system. The two-bedroom corner units at Fourth and M have some pretty nice views of The Yards and DOT (but I think they're all already spoken for). Twenty of the one-bedrooms and one of the two-bedrooms are for the mobility-impaired. A web site for the building will be launched soon, and there will be a rental office on-site. With Building 2's opening, there are 300 new affordable housing units now available in the Capper Hope VI redevelopment (with Capper Seniors #1 having opened late in 2006), with another 400 to come as mixed-income Capitol Quarter gets underway early next year, and the other mixed-income Capper apartment buildings planned for Second Street loom farther at some unannounced date in the future.
