Boffrand demolished the service buildings to the west of the courtyard, replacing them with a new wing for the
Palatine officers. The new wing preserved the style of the old
corps de logis to the east and incorporated vestiges of the
Couvent des Filles-du-Calvaire, founded by Marie de Médicis in 1622. These can still be seen in the winter garden and the
Mannerist interior of the Queen's Chapel. Between the street and the courtyard Boffrand added an entrance screen which connected the old to the new. The focus of the décor was high in the
spandrels between the arches, not in the wall panels as seen with Lepautre. This principle, first employed by
J. H. Mansart at the
Grand Trianon, kept the main part of the wall surface free for hangings, such as tapestries and paintings. The band of ornate spandrels running around the room achieves a unity, which is further emphasized by the slightly vaulted ceiling. Boffrand's decorative motifs, "the linked C-scrolls entwined with palmettes and festoons," are more similar to those of
Jean Bérain than Lepautre. File:Porte du Palais du petit Luxembourg Pl45 Livre d'architecture par G Boffrand - INHA (cropped).jpg|Coach entrance on the rue de Vaugirard from Boffrand's ''Livre d'architecture'', 1745 ==Later history==
