Lluís Domènech i Montaner (1849-1923), the great modernist architect, continued the work on Palau Montaner, after Josep Domènech i Estapà, the building's first architect, left the project due to disagreements with the property owner. Despite the creative freedom that the building's owner, the publisher Ramon de Montaner i Vila, granted to Domènech i Montaner to build his family mansion, the architect decided to continue the work from the frame built by his predecessor, to include ornamental elements and to extend the planned eaves to soften the severity of the lines and give it character.
