A couple enlist Butler Armsden Architects and Leverone Design to reimagine their home as a multigenerational meeting point. In 1963, landscape designer Lawrence Halprin devised a master plan for a community that would live in harmony with the natural environment. The resulting Sea Ranch, which stretches 10 miles along the Pacific coastline in Sonoma County, California, is characterized by timber-frame, wood-clad structures that are in dialogue with the local climate and terrain. Sited on a bluff within this pioneering community is the vacation home of a lawyer couple. After purchasing the residence in 2007, they lived in the home as it was for four years, even keeping the previous owners’ furniture. Envisioning a retreat that would accommodate their extended family and guests, they then recruited Butler Armsden Architects and Leverone Design to help guide the project.

Anna Hoover, founder of the non-profit First Light Alaska, sought a "thought refuge, a room with a view to sit and contemplate future projects and reflect on recent travels and interactions, plenty of ‘headspace’—tall ceilings—and the ability to host other artists for studio time," she says. A longtime resident of the Pacific Northwest, Hoover was familiar with the work of Olson Kundig and contacted the Seattle-based firm to design her abode.
