Welcome. We are an architecture and interiors studio that believes in the power of thoughtful design to better connect us to the built environment, the landscape, and each other. Our process is equal parts creativity and pragmatism –so that our work draws out the strongest potential of any site, the resources at hand, and ultimately, the experience of our clients. Design is both a process and an adventure; we see ourselves as both your partner and guide. We look forward to hearing from you.

Leit House:
Blackened volcanic rocks, surprising in their lightness, inspire the distinctive roof of this Sonoma fire-site home>

Millions of years ago, the fiery volcanoes of Sonoma Valley spewed hot magma across the landscape. As the lava cooled, the eruption’s gases became trapped, forming porous cavities instead of crystallizing into dense stone. In 2017, fire transformed this landscape again, revealing the ancient igneous rocks still strewn across the burnt, yet strangely beautiful and resilient, landscape.

Green House

The original home designed by Frank Lloyd Wright’s protégé, Aaron Green and built by Echler Homes in 1966, is a modern masterwork in Palo Alto, California. Remaining preserved in time by its original owner until 2019, its new owners, a young couple with two young children and one on the way, needed additional space and amenities. But how to update and extend Green’s low-slung complete thought for a new era and new growing family?

Lichen Trellis:
The delicate shadows of lace lichen inform a sun shade>

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.
