At the entrance to Carrer Jonqueres, Carrer Ortigosa and Carrer Ramon Mas, we find the annex building of La Caixa de Pensions per a la Vellesa i d'Estalvis (Old Age Pensions and Savings Bank). Both buildings, designed by Enric Sagnier, located opposite each other, share many formal characteristics.
The Casal de la Previsió, as it was originally called, is a partially isolated corner building, which touches the back of the Palau de la Música. It uses white Garraf stone for the main façade, combined with tiles on the secondary façades, as does the Casal de l’Estalvi. It also coincides with the latter in the neo-Gothic language of the finishes, although it responds to a much more modern typology close to the new conceptions of office buildings.
The main façade combines rounded walls at the corners and the central body with flat, high bodies with battlements, with a medieval aesthetic. This façade has sculptural ornamentation attributed to Eusebi Arnau. At the back of the building, corresponding to the streets Ortigosa and Amadeu Vives, there is a doorway decorated with reliefs that gives access to the part of the building occupied by large dwellings.
