'[11] He hosted the Duke of Buckingham, who came to escort Henrietta Maria to England, at the Hôtel de Chevreuse.
He commissioned the royal architect, Clément Métezeau, to design a Parisian townhouse, the Hôtel de Chevreuse, constructed 1622–1623 on the Rue Saint-Thomas-du-Louvre on a site now part of the Cour Napoléon of the Louvre.
