At this home on the Big Island's North Kona Coast, large open spaces for gathering and relaxing are mirrored both inside and out. In the main indoor gathering area, sunshine streams through sliding glass walls and elevated gable windows, illuminating a ceiling of Alaskan yellow cedar planks that express the interior volume of hipped roofs. Columns fashioned from battered-edge black granite and clefted limestone signal passage to the outdoors, where a generous covered lanai acquaints one with the home's ocean views.
