Local development watchers have noted the closure and gutting of Sky Nails across from the yuppied-out Flats at Atlas on Bladensburg with interest, wondering whether it won’t become a new condo building with ground floor retail, considering how quickly the eastern end of H Street seems to be on the ascent. But alas! According to broker Gregori Stewart, who handles quite a bit of property in that immediate neighborhood, it’s destined to be a single-story 7-11. Hey, at least it’ll be useful when Eastbanc gets around to redeveloping the CVS across the street.
