The design is integrated into the landscape as an extension of these gestural landscape walls. The retreat is hidden-in-plain sight with a roof that mirrors the planted ground plane but simply lifted at one end. The Prow’s vectoral shape references the concept of motion as the campus is the epicenter for a plethora of transportation modes spanning across land, sea, and air. The structure’s wing form symbolizes Expedia Group’s mission to aid in the art of travel. Approaching from within the campus, one is met by two black portals positioned within a single-story stone wall.

Inside, one is surrounded by a singular room crafted from natural materials. The northern and eastern walls are solid, while the southern and western walls are glazed — framing panoramic views of Mount Rainier and Elliot Bay. The glazing opens to a floating deck covered by a 50-foot cantilevered roof plane. Indigenous Pacific Northwest materials define the palette, creating a biophilic space honoring the region. The walls are constructed from the same stone as the riprap found along the Elliott Bay shoreline, while the floors and ceilings are crafted from local Douglas Fir trees.

The steel structures and rough sawn cedar siding are stained or painted black, highlighting the warm wood and stone.
