Entry Description

The crisp, pure sunlight of California’s wine region sparked the concept for this century-old former hay barn–a contemplation on light–while the context of the surrounding vineyards and site-specific art installations challenged WDA | William Duff Architects to provocatively transform the structure for contemporary use. The barn’s wood-slatted shell screens sunbeams, creating ever-changing patterns on the new concrete floors. Internal illumination turns the barn into a lantern at night. Two new opposing glass volumes with mirrored-walls reflect both the spaces within, as well as the outdoors.


William Duff Architects specializes in thoughtful, innovative architecture across the San Francisco Bay Area and beyond. Its elegant design solutions respond to their context with an artist’s understanding of when to use restraint or expression. With capabilities in multiple sectors, WDA is known for an award-winning and diverse portfolio of residential, workplace, hospitality and retail environments.
