Our sustainable preservation approach honors the past while accommodating change

Historic Preservation

Hennebery Eddy specializes in crafting historically sensitive projects that integrate existing architecture with modern elements to give those stories new life. Our Historic Resources Group is a specialized team of in-house experts that leads historic projects through identification, documentation, planning, and implementation. The group includes LEED-accredited, licensed historical architects and preservation design staff who are cross-trained in materials conservation and architectural history — and who meet or exceed the U.S. Secretary of the Interior’s Standards for Qualifications for Historic Preservation Professionals. Overlaying our firm-wide focus on achieving sustainable goals for all projects, we deliver projects with long-term stewardship in mind.

Our Philosophy Is Centered On Change

The U.S. Secretary of the Interior’s Standards for Rehabilitation recognize that change is often linked to a historic resource’s continued longevity. We seek creative approaches to protect a structure’s historic and cultural integrity while incorporating the inevitable changes into a building’s ongoing story. The result of our approach has been a series of highly regarded, award-winning projects that retain their historic integrity while also providing for long-term use.

Sustainable Preservation

Extending the usable life of an existing building offers enormous savings in energy and raw materials while also providing an opportunity to incorporate modern sustainable concepts. Hennebery Eddy considers historic preservation to be a high level of sustainable design, as it is based on preserving our natural and cultural resources as well as conserving our existing building stock and reducing the amount of embodied energy associated with constructing a new building. We apply the same concepts, processes, and technologies used in new construction to historic building projects — having a positive impact on people and community.

Specialized Programs for Your Project

Our Historic Resources Group has deep experience with all facets of the historic tax credit process, including eligibility determinations, property nominations, existing conditions documentation, Part 2 Applications (description of work), and Part 3 Applications (post-construction documentation). In addition, the State of Oregon has a Special Assessment of Historic Properties program, which amounts to a tax freeze.
