[1] The large greenhouse of Malmaison was begun in 1804 for the Empress Josephine by the landscape architect Jean-Marie Morel (1728 - 1810) and completed by the end of 1805 according to plans by Jean-Thomas Thibault (1757-1826) and his partner Barthélemy Vignon (1762-1846).

The greenhouse of Malmaison can be considered the forerunner of the great glass and metal architecture of the 19th century.

It was about 50 by 19 metres (164 by 62 ft) and was divided into two distinct sections: The park was designed in the English style, also by Louis-Martin Berthault, named as landscape designer to the Empress Josephine.

The rooms were partly redecorated in 1828 by the new owner, the Swedish banker Jonas-Philip Hagerman.

After the sale of the estate in lots in 1878, in 1887 the Petite Malmaison became the property of Pascal of the Two Sicilies (1852-1904), Count of Bari, youngest son of Ferdinand II of the Two Sicilies, who lived in his Parisian hotel at 8 avenue Matignon, but died in the Petite Malmaison in 1904 .
