This ultramodern $3 million home in Potomac, Maryland, is all drama from exterior to interior, with a drop-level dining room, slanted floor-to-ceiling windows, multiple kitchens and intricately tiled, geometric-shaped rooms. To top it off, the residence comes with two pools, a spa and a gazebo. Listing by Jonathan D. Taylor and Maxwell E. Rabin, TTR Sotheby’s International Realty
