Sometimes the distinctive feel of a site forces us to look more closely to fully understand its sway. Here, at the top of a Sonoma ridge, we found a knoll of massive oaks draped in Ramalina lace lichen, also known as Spanish Moss. Beautiful, but also inspiring to us as architects because of the deeply dappled outdoor ‘rooms’ the veils of lichen create.

Enamored by the atmospheric lace lichen shadows cast around this site’s mature oaks, we set out to evoke the essence of those spaces with aluminum and rivets. With help from our enthusiastic contractor, we used a series of metal fins strategically fixed with pop-rivets to create an undulating pattern. The proof of concept, however –even more than the form and beauty of the trellis itself– was in the delicacy of the shadows they cast.
