While it’s not in Columbia Heights, this still may be of use to folks in northern parts of the hood: Annie’s Ace Hardware is now open at 1240 Upshur Street NW. It looks to be pretty darn big — 6,500 square feet.
Park View DC has a preview of the shop, and the Post writes about it too. They don’t have a website that I can find, but they do have a Facebook page and Twitter.
Of course, there are already some hardware options closer to our area: Old School Hardware at 3219 Mt. Pleasant Street NW and Cooper Hardware at 3459 14th Street NW. Old School even has online ordering and a blog.
