The design: Built for easy entertaining, the living-dining area and kitchen flow together. The table can slip outside for a summer dinner. Three bar stools tuck under the counter. The built-in birch cabinets and slate backsplash match materials used throughout the house.

The twist: The kitchen's countertops are made of a renewable lightweight composite concrete. A split-level counter hides faucet and dishwasher. An extra mini sink in the upper level is handy for icing drinks and washing vegetables.
