The small Oval Boudoir adjoining the Bedroom, which once used to be draped in muslin and therefore called the Canopy, was redecorated in accordance with Voronikhin's design to match the Bedroom, with its stucco facing on the walls, its painted garlands of flowers, etc.

Both the interiors are good, examples of the vogue for flowers characteristic of the beginning of the nineteenth century. Floral wreaths and festoons are to be found not only ,in the wall and ceiling painting, but also in the upholstery of the furniture, in the design of draperies and carpets. Growing flowers in jardinieres and cut flowers in vases, used in great profusion, strengthened the effect of floral motifs in interior decoration.

The Oval Boudoir opens onto a portico with six marble columns, also built by Voronikhin, to which Rossi later added a porch with a wrought-iron railing and awning, decorated with flowers and plants and offering a charming view of the flowering shrubs and the paths of the Private Garden.
