Daughters go to college—that's typical. But when they come home for the summer to find their parents now living in the neighbor's house? Not so typical. That's exactly what happened to Sue and John McKinley's twin daughters when their parents downsized to a house just two doors down. "We were already familiar with the home and liked its open floor plan and high ceilings," says Sue. "We just customized the interior to suit our tastes." In their kitchen, the couple worked with designer Suzanne Kasler to combine practicality with style.
