APT DC is now accepting presentation abstracts for the 2026 Fall Symposium, which will take place at the Alexandria History Museum at The Lyceum in Alexandria, Virginia, on Friday, September 11, 2026. This year's theme is Adaptive Reuse: Policy in Practice.

Since its creation in 1976, the Federal Historic Tax Credit has shaped the nation’s built environment and changed how Americans view historic landmarks and neighborhoods. The federal historic tax credit, along with a number of state tax credits, has incentivized the reuse of historic buildings across the country.

Former warehouses, textile mills, railroad stations, firehouses, hospitals, banks, office buildings, and even gas stations have been saved from demolition and converted to new uses that continue to serve their communities. Thus, rehabilitation/adaptive reuse has become one of the most popular and visible aspects of historic preservation in the United States.

50 years later, the 2026 APT DC Symposium seeks to explore various aspects of the rehabilitation treatment’s theory and practice – through both its development and utilization over the past 50 years, but also its future application.

Historic millwork expert Brent Hull provides a one-of-a-kind, comprehensive reference of millwork elements found in historic homes from the 18th to 20th centuries. His latest book, Millwork: The Design and Manufacturing of Historic Millwork from 1740–1950 is organized by type of millwork for ease of reference and includes rare illustrations, hard-to-find drawings, and diagrams from the 19th century, many of which are sourced from out-of-print catalogs in Hull’s private collection. This presentation will explore the classification and definition of doors, windows, moldings, mantels, paneled walls, built-ins, and other millwork elements through a historical lens.
