Unless you've been busy planning your NCAA bracket for the past 12 months, you've probably noticed that workplaces have completely transformed. (And if you were working on your brackets, they're probably all busted now anyway.) Most firms are shrinking footprints, eschewing offices for open-floor plans, and some are even ditching the office altogether for co-working hubs like WeWork (we recently snapped one of the firm's DC locations).

Crystal City, Va. was once a drab home to government agencies and defense contractors, but is now reinventing itself as a haven for tech firms. Vornado, the neighborhood's biggest landlord, is leading the charge with DesignLab, a full floor of six tech-focused spec suites each designed by a different architect. (In the RTKL-designed space, we snapped the firm's Nathan Ferrance, Dennis Gaffney, Liz Wozny, and Matt Karner.)
