In Arlington, Va., larger lots are increasingly hard to find, so when a local couple landed one, they saw an opportunity to take advantage of the site with a wide, open floor plan and 12-foot ceilings. The contemporary Arlington home spans 6,500 square feet and was built and designed by architecture, interior design, and build firm ODE Design. Most homes in this neighborhood sit on tight lots and tend to make use of vertical space, says Yuri Sagatov of ODE Design.
