Various transformations were effected for the relatives of Pope Clement XII Corsini in the Palazzo Riario alla Lungara, which had been modified for Christina, queen of Sweden in the previous century but later became the Palazzo Corsini alla Lungara, purchased on 27 July 1736 from Duke Riario by Don Neri and Don Bartolomeo Corsini, for 70 thousand scudi. After Christina's death in 1689, her sculpture gallery and her library were emptied. Fuga was called in to pull together the 15th and 16th-century amenagements for the Corsini brothers, works which took from 1736 to 1758 before all was finally completed. The Corsini retained Christina's bedroom just as she had left it, and the "urban" front in piazza Fiammetta had to be left untouched, but the weight of her library had produced cracks in the vaulting below it, and repairs to the existing structure were not finished until 1738. Fuga worked on the garden front of the palazzo, beginning with work on the library wing for Neri Corsini. In 1751-53 he added an identical central block containing a theatrical divided staircase, lit with large windows that looked onto the garden parterres, which had been modified and brought up to date in 1741. Then the two were linked with a ground-floor portico. In the interiors, fuga managed in innovative ways to maintain a separation of the functional service circulation from the suites of parade rooms.
