Civil building located on the sea front of the town, oriented in such a way that it has a view of the sea. In the design of the building, much importance is given to the front, which is the only one with decoration.

The complex has a rectangular, elongated and narrow floor plan, and consists of a ground floor, two floors and a roof.

In front of the access door a small porch stands out, on two pillars and two pilasters, which supports the balcony of the upper floor. The second floor is organised by means of six small windows in the shape of a semicircular arch.

The decoration is the most interesting element. It follows a historicist style, with special reference to the Middle Ages with large mouldings, plant elements, chimeric animals and heraldry, represented by the Catalan shield in the centre of the façade.

House between partitions with a rectangular plan set back from the street plan with a front yard. It consists of a semi-basement, ground floor and two floors with a flat roof that can be used as a rooftop.
The main façade, facing south, is generated from a symmetrical composition with two axes of symmetry on the ground floor and first floor. On the ground floor, which is at a higher level than street level, the entrance porch with built-in dragons stands out, which is the base of the balcony on the first floor. This balcony extends across the width of the façade and has two openings with sculpted stone dust guards decorated with floral motifs. In the middle of the two openings is the sculpted coat of arms of Catalonia.
The window with handle on the ground floor and the semi-circular arched gallery on the upper floor are also noteworthy. Crowning the façade is the stone sill of the roof, with a decoration of plant motifs and terracotta vases on the sides.
The finish of the façade consists of floral sgraffitos on a yellow background.
The interior mixes different historicist styles specific to the time. On the ground floor there is a living room, a dining room and a neo-Arabic style interior courtyard covered with a glass skylight. On the second floor there is a large music room presided over by a French piano from 1849, a bathroom and a bedroom made of jacaranda wood. Upstairs there is a studio bedroom made with boat furniture.
The furniture, stucco walls and ceilings, made of Cuban mahogany wood, are the work of Josep Ribas, and the rest of the interior decoration by Josep Canudas.

The Matas family gave this house to their daughter, Eulàlia Matas, on the occasion of her wedding to a member of the Sanahuja family. For the Matas, it was their way of showing their economic power and it seems that they considered paving the floor with silver.
