I just saw this on DCist, the Nevin Kelly gallery has moved from U Street to the Highland Park building at 1400 Irving St NW. The gallery folks told DCist that "they will be open by appointment only until the new year, when they'll host an open house to introduce everyone to their new digs, followed by regular business hours again."
The gallery doesn't have a storefront and are in one of the first floor units, and they hope to use the building's common areas and such as reception and exhibition space. Seems like kind of a weird set-up, but I have yet to see it, so who knows.
This is the first art gallery in the neighborhood (if you don't count BloomBars, which is more of an art space), and I hope we can see more.
Here's their website.
