One of the best: the National Association of Realtors headquarters. (Lydia DePillis)

It’s easy to hate on downtown D.C.’s office buidings, squished as they are by the height limit. And some of them are truly heinous. But others—-even the modern ones—-are actually quite handsome, and ought to be recognized. So I’ve spent a bit of time over the last few weeks noticing the architecture downtown, and have narrowed down my completely unschooled, fairly arbitrary judgments to six favorites and six disfavorites. For the purposes of this slideshow, I’ve also omitted from consideration the historic buildings that have endured over the last century, figuring the competition wouldn’t be quite fair.

Here it is. Feel free to disagree!
