Building a better future together
Our sustainable stewardship.
Through preservation, adaptation, transformation, and renewal, we contribute to the health and well-being of people, communities, and the environment.
PROOF IS IN THE Practice
Driven by Performance
Performance analysis is a creative, rigorous, and critical part of our process. We apply expertise and innovative tools to achieve high-performing buildings.
Setting the Bar
Our certified professionals in frameworks such as LEED, Passive House, WELL, Living Building, and the AIA Framework for Design Excellence drive projects forward to achieve measurable sustainable results with lasting value.

Carbon leadership
We’re carbon action advocates and thought leaders. We support and participate in COP26, Architecture 2030, Carbon Leadership Forum, Zero Net Carbon Collaborative, and other climate initiatives.

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.
