Charles de Brie was inspired to start modernisation early in the 16th century, but lack of funds meant the project was halted with only the North Tower completed.
By using Charles de Brie's original plans and the same russet schist and white tuffeau stone, Bautru ensured that there was a continuity of design.
The central halls, two wings and the South Tower were added, with Jules Hardouin-Mansart completing the work of Bautru by building the chapel.
The duke assigned Luciene Magne the task of restoring the château and several features were added, including parapets and cornices.
Descendants of the La Trémoïlle family still own the château, but in the 20th century, it was modernised with cellars and the introduction of electricity.
