Headquartered on the Pacific coast and engaged globally, KAA Design Group has been shaping residences since 1988. Founded in Los Angeles, the firm has spent nearly four decades crafting homes that honor both tradition and innovation -weaving architecture, landscape, art, and craft into a singular and enduring vision.

​

Our work is rooted in the conviction that architecture and landscape are inseparable. We approach every commission holistically, shaping land, light, structure, and garden as one composition. Buildings are not placed upon sites; they emerge from them -formed by climate, materiality, and the rhythms of daily life. This integrated design approach remains one of our defining principles and enduring differentiators.

​

Over the years, we have become known for sculptural, site-responsive residences that dissolve the boundary between indoors and out. Our homes are conceived as personal sanctuaries  -heirloom structures grounded in clarity of form and warmth of material. They are crafted to gather families, frame views, welcome nature, and elevate everyday experience.

​

This philosophy is articulated in our monographs, Residing with Nature (Rizzoli, 2024) and California Contemporary(Princeton Architectural Press, 2018), which explore our belief that beauty is essential to human happiness and that thoughtful design can deepen one’s connection to place.

Led by founding principal Grant Kirkpatrick, FAIA, and partner Duan Tran, AIA, the firm thrives on collaboration -between client and designer, architecture and landscape, tradition and forward thinking. From Montecito to Manhattan Beach, Napa to Cabo, Dubai to Japan, our work reflects a fluid practice equally at home in local neighborhoods, regional landscapes, and international contexts.

​

At its core, KAA Design does not simply design houses. We design environments for living -rooted in California’s creative spirit and guided by a timeless dialogue between people and nature.
