In 1742 the Carmes-Billettes began construction of a larger church, They chose the architect Jacques Hardouin-Mansart de Sagonne (1711-1778) grandson of Jules Hardouin-Mansart, the founder the famed Mansard dynasty of architects.

He designed a larger church for Les Billettes which increased the number of worshippers from 960 to 1200. Comstruction of the new church lasted from 1754 until 1758. From the original medieval church only the cloister was preserved. During the French Revolution, the church was closed and sold. The cloister was used as a workshop for carpenters, while the church was used to store salt. In 1808, the Emperor Napoleon authorized the city of Paris to buy the church, which was then transferred to the Consistory of the Lutheran Church, which was looking for a Paris home.
