The sawdust has cleared and the doors are open at the new Roche Bobois  showroom in River North. It’s located in the same building just across the hall from the old space, but it’s got a decidedly more contemporary feel (think slick cement floors and dropped soffits). But it’s the size that matters here—the 10,000-square-feet space is triple that of the former, and it can now house an expanded range of Roche Bobois’ furniture and accessories. Look for the new management to host a grand opening party in January (date TBD), and for an intriguing collaboration with fashion designer Sonia Rykiel to debut spring 2011. For now? There’s a bevy of cool, custom designs from both the Les Contemporains (contemporary) and Les Voyages (eclectic international) collections to be snapped up just in time to elicit some serious envy from your holiday guests.
