Considering that award-winning architect David Jameson's M.O. is to bring interesting architecture to the District, it's no surprise that the home he once called his own is equally stunning and unique. Jameson hasn't lived in this four bedroom tetris game of a house since 2011, but his contemporary stamp is all over it. Glass plays a huge role in the exterior, there's a small raised garden and two swimming pools, and of course, the layout is anything but boring. Ask is $2,195,000.
