Peter Kuttner, Prinicipal Architect at CambridgeSeven, talks about the creation of MBTA stations, focusing on the Porter Square Station. The architects worked closely with engineers, government agencies and community representatives to construct Porter Square Station, which serves both the rapid transit and the commuter rail systems. The goal was to create for this neighborhood a sense of place, and a sense of destination. This visually impressive station is situated 105 feet below ground under the heavily-traveled Massachusetts Avenue.
