firm + people

Based in New York City’s Lower East Side, Paul A. Castrucci Architects (PCA) is a mission-driven firm on the leading edge of sustainable, equitable, and community-centered architecture.

Situated at the intersection of affordable housing, climate resilience, and community activism, our work is driven by the need to create impactful change. For over 30 years, PCA has tackled systemic challenges with thoughtful, holistic solutions, designing human-centered environments that uplift and sustain communities of all sizes.

We specialize in designing healthy, high-performance buildings, integrating Passive House principles to foster environmental restoration, renewal, and a legacy of stewardship within the urban fabric.

With a client-centered approach, we ensure each project reflects the unique needs and aspirations of the people and communities it serves. We believe in architecture as a force for good—enhancing everyday life and laying the foundation for stronger, more connected communities.

Our robust, functional, contextual designs and advocacy efforts have earned recognition from leading organizations such as Northeast Sustainable Energy Association (NESEA), AIA Committee on the Environment, Greenbuild, NY Passive House Conference, and the NYC Department of Design and Construction (DDC).

Our work has been featured in respected publications such as The New York Times, Oculus, Dwell, The Architect’s Newspaper, Inhabitat, and Green Building Advisor. Among our accolades are three New York State Energy Research and Development Authority (NYSERDA) Buildings of Excellence Awards, honoring our dedication to designing resilient, climate-friendly multifamily buildings that prioritize health, equity, and sustainability for residents and their communities.
