Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Now complete the following example -
Input: In the spring of 1948 Pei was recruited by New York real estate magnate William Zeckendorf to join a staff of architects for his firm of Webb and Knapp to design buildings around the country. Pei found Zeckendorf's personality the opposite of his own; his new boss was known for his loud speech and gruff demeanor. Nevertheless, they became good friends and Pei found the experience personally enriching. Zeckendorf was well connected politically, and Pei enjoyed learning about the social world of New York's city planners.His first project for Webb and Knapp was an apartment building with funding from the Housing Act of 1949. Pei's design was based on a circular tower with concentric rings. The areas closest to the supporting pillar handled utilities and circulation; the apartments themselves were located toward the outer edge. Zeckendorf loved the design and even showed it off to Le Corbusier when they met. The cost of such an unusual design was too high, however, and the building never moved beyond the model stage. Pei finally saw his architecture come to life in 1949, when he designed a two-story corporate building for Gulf Oil in Atlanta, Georgia. The building was demolished in February 2013 although the front facade will be retained as part of an apartment development. His use of marble for the exterior curtain wall brought praise from the journal Architectural Forum. Pei's designs echoed the work of Mies van der Rohe in the beginning of his career as also shown in his own weekend-house in Katonah in 1952. Soon Pei was so inundated with projects that he asked Zeckendorf for assistants, which he chose from his associates at the GSD, including Henry N. Cobb and Ulrich Franzen. They set to work on a variety of proposals, including the Roosevelt Field Shopping Mall. The team also redesigned the Webb and Knapp office building, transforming Zeckendorf's office into a circular space with teak walls and a glass clerestory. They also installed a control panel into the desk that allowed their boss to control the lighting in his office. The project took one year and exceeded its budget, but Zeckendorf was delighted with the results. 
Question: What office building did the team that designed the corporate building for Gulf Oil redesgn after adding more associates?
Output: 


Output: Webb and Knapp
