D.C.’s intercity bus depot, in the parking garage behind Union Station, got a whole lot more interesting last fall after a revamp by Studio Twenty Seven Architecture. The makeover’s standout element is a pair of connected ovoid pods, one an information booth, the other a store. Which happen to be inscribed with a verse from a Death Cab for Cutie song. In Morse code. Indie rock lyrics aren’t the only improbable design element of this odd structure, which opens for business this spring. We got the scoop from the head designer, Todd Ray.
