Welcome to OSA!
We’re a design-led architecture and design practice based in California, driven by curiosity, collaboration, and a deep respect for context. At the heart of everything we do is a passion for creating thoughtful, enduring spaces that celebrate the connection between people, place, and material.
Our projects range from intimate, custom residences to public and cultural spaces. Whether we’re designing a coastal home or a welcoming hospitality venue, every project starts with listening—to our clients, the community, and the unique character of the site itself. We pay special attention to light, craftsmanship, and how spaces feel, ensuring our designs feel authentic, responsive, and enhancing to those who live, work, or gather in them.
We believe architecture should be both poetic and practical. That’s why we blend refined aesthetics with environmental responsibility and a strong focus on wellness and livability. Sustainability isn’t just a buzzword for us—it’s woven into our process. We design buildings that age gracefully, respect their surroundings, and contribute positively to the world around them.
At OSA, we’re committed to creating spaces that tell meaningful stories—spaces that feel grounded, generous, and full of life.
