Preserving Special Places

Our work is grounded in a deep understanding of each unique place. We help to preserve, enhance, and celebrate the continued utility of many significant buildings, landscapes, and infrastructure. With our clients, we are stewardship partners for special places and the communities defined by them.

Adapting & Transforming

Revitalizing existing buildings is the most sustainable approach to building. We understand the value of current resources and their context. We preserve the past—transforming and renewing—to support the future adaptability and resilience of communities.

Creating Positive, Lasting Impact

We foster a creative and healthy balance that incorporates the needs of occupants, communities, heritage, environmental systems, and climate.
