The Agell House, due to its proportions, takes on a stately character. The typology adopted brings us closer to the characteristic of medieval palaces, since the square plan generates a courtyard in the middle and, around it, a gallery. The arrangement, on two of the building's flanks, of two towers that protrude from the volume recalls fortified palaces. The building, with two floors, has a hip roof of flat lace tiles, and with a barbican supported by panels. The semicircular porch that gives access to the entrance is surrounded by Ionic columns that support an open terrace on the first floor. On the opposite façade there is a porch terrace, on the central gable of which there is a relief of an almond tree, emblem of the original owner's family. The arrangement of the main access; the appearance of terraces and porches where Ionic columns alternate and, in others, semicircular arches, give the building certain medieval and, at the same time, classical echoes. In the openings, the application of sgraffitos with filigree details (the work of Joan Mirambell) and on one of the sides the arrangement of a built-in bench with the back of decorated tiles (the work of Francesc Domingo) have just given the building of a nineteenth-century character. This bench is tiled with ceramic borders and floral motifs, and at the top there are three designs. In the one in the centre, an almond tree with the inscription "L'Ametler, arbre de Catalunya" appears. The side drawings show a girl with a basket of flowers and a farmer. As it was an isolated tower, it was the architect Rubió i Tudurí who designed the extensive garden structured geometrically by topiary art, and let the eleven hectares of forest that surround the property grow more spontaneously. The tower was built on an extensive rustic property very close to the old chapel of Santa Elena d'Agell, mentioned already in the 10th century, and the Mas de "Ca l'Arnó", today called "Cals Frares" (1235), which for a few years was the manor of the property. Since the 18th century, the land was owned by the family of Teresa Amatller i Cros (1873-1960), daughter of the prestigious chocolatier, who was the promoter. A first project is due to Josep Sala i Comas, but in 1918, it was Lluís Bonet i Garí who took charge of it. In 1943, Antoni Amatller gave the house to the Women's Section, which used it for a hostel. Recently, the Generalitat de Catalunya acquired the house and conditioned it to function as a hostel for colonies. The works of rebuilding roofs, restoring and consolidating façades and adding a new building were directed by the architect Agapit Borràs. Currently, the building is part of the national network of social hostels in Catalonia.
