About PAS

Our Story. Our Vision.

Designing Places That Matter — With You, For the Future

About PAS Architects: We are a purpose-driven adaptive architecture firm rooted in listening — to the land, to our clients, and to the context of every project. Founded by Larry Phong, a licensed architect in both California and Texas, PAS Architects stands as a leading California architecture firm focused on creating sustainable, thoughtful spaces. Guided by passive and adaptive principles, our work as a sustainable architecture firm is about designing places that endure — places that serve people, elevate daily life, and respect the planet. From vision to construction, we build with clarity, care, and long-term impact.

The Spark Behind PAS

“Architecture is a dialogue — with site, climate, and community. I believe our job is to listen first, then respond with care and clarity.”
Larry Phong, Architect
