[4] From 1695 he succeeded Giovanni Antonio de' Rossi as architect of the Monte di Pietà in Rome and finished the work on its chapel by 1700 where the dome is decorated to his design.
From 1709-12[1] Bizzaccheri was the architect of the Palazzo di San Luigi dei Francesi in Rome[5] and from 1712-19 he worked for the Tribunale delle Strade.
Bizzaccheri was never assigned any major tasks but nevertheless played an important role in the transformation of the borrominesque vocabulary into the language of Roman rococo.
This is exemplified by the facade of Sant’Isidoro a Capo le Case, his most distinguished work, which he constructed from 1704-05 using the extant staircase and portico.
The chapel was begun by Mattia de Rossi in 1690 and finished by Bizzaccheri from 1694–96 in tones that would determine the colour scheme of the rest of the church in the mid-18th century.
