1730 Pennsylvania Avenue

Washington, DC | 2009

Our renovation at 1730 Pennsylvania Ave. integrated performance, design excellence and execution to repair the failing façade of a high–profile building only steps away from the White House. A structural evaluation revealed that the stone cladding was unstable. For the client, Tishman Speyer, it was an opportunity to change the image and metrics of this commercial office building with a catch: the building's tenants could not be displaced. 

Our focus on performance was defined by a number of criteria: daylight and vision, increased façade performance by decreasing air and water infiltration, and decreased envelope surface area for both initial cost and long–term maintenance. The project is a successful case study for improving our aging buildings. It advocates that good design is good business: investing in existing buildings to improve metrics, image and increase profitability.
