In 1905, Bartomeu Terradas Brutau commissioned Josep Puig i Cadafalch to design a house for each of his three sisters, Angela, Josefa and Rosa.

The result was a building reminiscent of old medieval castles, with elements of different architectural trends and various technical innovations, with six pointed towers (crowned by conical spikes), one of its distinctive features which gave the popular name of Casa de les Punxes.

Bartomeu Terradas i Mont, despite leaving his son as heir, did not forget the welfare of the women in the family and left a small monetary fortune divided between the three daughters and his wife.

Moreover, in the representations of the Roman Numerals the four signs of the zodiac associated with the four seasons are added: Capricorn (winter), with horns that symbolize the hunt; Aries (spring), surrounded by flowers; Libra (autumn), with grapes, and Cancer (summer), in the water.

In a phylactery on top of the clock, we read: «Numquam te crastina fallet hora», a phrase taken from the «Libro I» of The Georgics, by Virgilio, which means, ‘tomorrow will never fail you’.

Josefa's property went from Avinguda Diagonal to Carrer Rosselló, in whose rear façade we find another ceramic panel drawn by the same Monserdà, where it represents Sant Jordi slaying the dragon and reads: «Patron Saint of Catalonia give us back our freedom».

Just under this panel, in a strategic position due to the meaning that the figure of Sant Jordi represented, we encounter a sculpted face that results familiar.

The male figure, with round glasses, important hair entries and pouty lips, represents the great author of the project, the architect Josep Puig i Cadafalch.

The construction works were carried out during 2004 and were recognized by the Urban Land Institute Europe Excellence Award as one of the top five European heritage interventions.

On the completion of the construction works of the first of three houses, Monserdà set up his studio-workshop in one of the round ends of la Casa Terradas on the corner of Avinguda Diagonal with Carrer Rosselló Thus, his designs are the decorative elements of artificial stone that fill the façade, the ceramic panels of Sant Jordi, the Angel and the roses, and the design of the windows and elements of artificial iron.

When he finished his education, in late April 1900 together with his brother Josep he opened a workshop of stone cutting and sculpture on the street of Muntaner, 31, Barcelona, called Hermanos Juyol that would soon acquire a deserved prestige.

He was a perfectionist, which led him to review the wax models before sending them to the foundry, or to make mockups of the decorations for the façades of the buildings he was commissioned.

Ramon Eudald Amigó i Dou (Barcelona, 1818–1885), a glass painter, was a great glazier artist and performed very important work.

For example, he collaborated with the architect Joan Martorell in the restoration of the Gothic windows of the church in Santa María del Mar and the University of Barcelona, amongst many others.

In 1900, Casa Ballarín modernized and popularized the forging sector and incorporated mechanized production of serial parts, which were presented in a catalogue and greatly reduced the selling price.

Refurbishments are also being conducted on the ground floor to recover the essence and the main features of the original building designed by Puig i Cadafalch.

The largest tower, occupying the corner of Avinguda Diagonal with Carrer Rosselló, contains three levels and offers a privileged view of the city.

It is also in this tower where one of the great technological advances in the world of architecture is captured, a constructive revolution, in which the architect takes to the extreme the structural advances: the floors no longer rest on vertical support elements, but by hanging steel straps operating tensile loads and transmit the weight of the ceramic circular perimeter walls, making them work in compression.
