Ray and Maryann Costa need to remodel their kitchen. Both know they need much more work space and cabinet storage. Michael Payne outlines the problem areas: the built-in breakfast nook, the cabinets and what type of materials to use for the counters and floor. He draws a plan for the Costas' kitchen that will expand the space by removing walls. When finished, it's a spacious, elegant room with lots of natural light, more storage and an airy quality.
