Located in the district of Gràcia, this house is located on a plot in which the south façade faces Mare de Déu del Coll Street, while Pineda Street faces the north façade.

Casa Sansalvador is not really a house, but a set of constructions designed by Josep Maria Jujol, which were never finished. Of the main house, only the foundation and the beginnings of the walls were built, which are still visible. The finished parts are the doorman’s house, the stables, the garden and the two fences on the street. The farm currently has access from Mare de Déu del Coll Street, in the lower part of the farm, from where you can access the facilities. The north access faces the unfinished house and is unused.

The element that organises all these constructions is a staircase that starts at the lower access and makes an upward journey through the entire estate, passing through the roofs of the stables, the garden and the remains of the house until reaching the upper access. This staircase, made up of different independent sections, gradually adapts to the topography changing direction and construction types depending on the area it crosses. The most elaborate section is the lower one that starts at the street portal and goes up between two exposed brick factory retaining walls covered with ceramic pieces and under a metal pergola.

The façade is asymmetrical, it follows the slope of the street and locates the two main entrances as free openings created in the smooth wall without any compositional modulation. The entrance to the stables has an irregular polygonal lintel and exposed brick jambs that are also irregular. The staircase is based on a toothed triangular arch of exposed brick which is richly ornamented with ceramic elements and sheltered from the rain by an eaves finished with two alternating levels of tiles. On the upper floor of the volume on the right, there are two windows surrounded by a band of exposed brick with geometric shapes and wooden shutters. The set of elements of the façade reminisces a certain Arabic inspiration.

The roofs are flat with walkable roofs. The main body has a brick lattice rail with ceramic details and the double height body has a tracery rail which is probably by another author.

On the slope of the garden and above the buildings there is the access to an old mineral water mine with supposed radiological and medicinal properties that the doctor decided to commercialise under the Agua Radial brand. This reason caused Sansalvador to decide to build grottoes to access the well that would bring the water to the bottling plant, as well as a romantic garden that would integrate them into a natural environment.

This space stands out architecturally because it includes an oval window and a hall with two parabolic arches containing a vault with a paraboloid surface. Artistically, we must highlight the careful work of the sgraffitos that appear punctually around certain architectural elements, combining floral motifs and dreamlike forms. The complex wrought iron grills of the entrances and complementary elements are also noticeable.

This construction constitutes a good typological example. It has an exterior or landscape interest rather than an interior one. It is a rarity for being one of the few works of Jujol's maturity in the county town, except for the Planells House and the Jujol School in Riera de Sant Miquel Street.

The house was not finished because during the construction of a well the owner discovered the medicinal qualities of the water, so he decided to begin its exploitation under the name "Agua Radial".

In 1932 they abandoned the works.

Refurbishment: 2007. Architect: Francesc Gruartmoner. In this project, some caves were uncovered, where presumably the well that wanted to be economically exploited was located, which run through the subsoil of the estate through several branches. Although most of the exposed stone appears as a product of the excavation, Jujol designed several parabolic arches of exposed brick with a structural function.
