Manor house consisting of a rectangular body parallel to the street, where the main rooms of the house are located, of which three are preserved in their original state.
At the beginning of the 20th century, it was considerably renovated and expanded, with two ground-floor buildings and two attached floors in the middle of the old building, forming a u-shaped courtyard that opens onto a large garden, which is accessed via Carrer del Cardaire (or Sant Fruitós). M. Viñals refurbished the street façade. This is a symmetrical, with a ground floor and two floors, with two higher bodies at the ends. It has balconies on the first floor and a rhythm of gallery-like windows on the second floor. The upper finish is made with a cornice rich in classic ornamental elements following an eclectic style. J. Puig i Cadafalch refurbished the interior: ground floor, grand staircase, rear extension and wrought iron tribune with leaded stained-glass windows that overlooks the courtyard, using his characteristic language of Flemish influence within the modernist style. The 18th-century wall paintings on the main floor and the 19th-century paintings by Alexandre de Riquer in the downstairs hall and main staircase stand out.
Former stately home where Joaquim de Sagrera i Domènech was born in 1777, he is celebrated for his active intervention in the French War and for the importance and expansion of his textile company. During the 19th century, the house suffered some vicissitudes in the rich architectural and decorative heritage it already had. It was deeply refurbished and restored in 1912 by the descendants of the family, who entrusted the work to the two architects mentioned. Some press campaigns and the action of the Museum Board prevented the demolition of the house in 1965. In 1973, with the financial help of the Caixa d'Estalvis de Terrassa, the city council acquired the building and it was destined for a museum. It contains several collections and they continue to restore the 18th-century style of its rooms.
