Historic Preservation

Preserving the past for the future

We have a passion for history and want to keep it fresh and relevant for generations.

Respect and revitalize

Throughout our decades-long historic preservation practice, we have respected, preserved, re-used, and revitalized important structures and landscapes through aesthetic sensitivity and technical expertise. Whether navigating complex approvals and historic tax credits, exploring practical, modern solutions for re-use, or achieving sustainability goals, we regard each project – no matter the size – as an opportunity to contribute to the longevity and relevance of our collective past.

Adaptive Re-Use: reclaiming history, creating impact

Re-using existing buildings, especially historic assets, challenges us to innovate for the greater good. Not only is re-use so much better for the planet – think of all the embodied energy that’s saved – but it also creates a positive social and cultural impact for communities. A historic postal facility or commercial bank turned into a neighborhood school, a historic courthouse converted to a community arts facility, or offices repurposed for housing, are all examples of the win-win of sensitive adaptations.
