Your building functions as a single unit but comprises countless moving parts and pieces—sometimes even multiple buildings. Our design teams are built to mirror this structure. With expertise across all functions and facets of design, we inject the design process with knowledge, collaboration, and partnership.
Highlighting and reinvigorating historic character and significance is a craft that demands careful and thoughtful design solutions. Cushing Terrell’s team of historic preservationists is equipped with knowledge of the most granular aspects of the built environment — aspects that transcend a moment in time.
Historic Buildings Reimagined
Our teams can advise on the adaptive reuse of buildings, an approach that values a structure’s original look but revitalizes it with a new purpose. The benefits of adaptive reuse are:
- Maintaining cultural heritage by repurposing properties for current needs.
- Reducing a community’s carbon footprint by maintaining some existing materials. Adaptive reuse of a building may save 50 to 75% of embodied carbon.
- Minimizing urban sprawl by using existing structures that often make up a city’s core.

“Every new project presents an opportunity to grow as a professional and improve our firm’s processes. We are constantly working to bridge the past and the future, using new technologies to study, preserve, and improve old buildings.”

A Full-Service Team
Cushing Terrell’s Historic Preservation team offers a wide range of historic preservation design, reporting, and planning services throughout the United States.
Our in-depth expertise covers materials and systems, building behavior and pathologies, historic materials and their uses and resiliency, and how weather and other outside factors impact both structural integrity and character-defining features. This knowledge provides our team with a substantial background for constructing and implementing preservation plans.
We offer full architectural services for all phases of architectural and engineering projects including preservation, restoration, rehabilitation, adaptive reuse, reconstruction, and sensitive new contextual design.

Collaborative and Technology-Enabled
Much of our historic preservation work occurs in parallel with Cushing Terrell’s other disciplines. We collaborate with architects, building envelope specialists, structural and civil engineers, electrical and mechanical engineers, and interior designers to bring forward unique solutions specific to each project’s needs.
From ground-penetrating radar to 3D building scanning, advanced in-house technology solutions help us fully understand the project at hand. We constantly seek out opportunities to incorporate new technologies, testing, and computer modeling into the planning and documenting stages of our process.
