Event description:
Join us for a guided, behind‑the‑scenes tour of the Cannon House Office Building, one of Capitol Hill’s most significant historic landmarks, following its 15‑year modernization and preservation effort. Led by Julie Pelletier, AIA, NCARB - Architect of the Capitol - and select project team members, this two‑hour experience explores the building’s history, renovation scope, construction challenges, and lessons learned while working in an occupied Congressional facility. Participants will visit unique spaces including the Rotunda, Guastavino Tile Vault, historic hearing rooms, the Cannon Caucus Room, modern fifth‑floor addition, courtyard, and Cannon Commons. The tour highlights how preservation, safety, and contemporary functionality were successfully integrated.
