The Joaquima Vendrell house is located on the corner of Carrer Vallhonrat and Passatge Prunera. It is a block of flats between partitions consisting of a ground floor, a mezzanine, six floors and a rooftop. There are five flats per floor, of about 76 m2, with an uneven distribution. The façade is articulated from the corner, rounded and symmetrical.
On the ground floor, the openings follow a regular rhythm and have the jambs marked by a plain moulding that ends in a rectangular piece in the form of corbels that support the lintel. The main door, located in Vallhonrat street, has a broken frame. This level has a stone slab facing, unlike the upper levels, which are plastered and painted.
From the first floor onwards, the façade folds into a triangular shape following two longitudinal axes on Carrer Vallhonrat, and another two on the Passatge Prunera. On these two façades, all the openings, which follow a regular rhythm, are lintelled, and on the first and fourth floors there is a continuous balcony that follows the triangular shapes. This fourth floor is crowned by a cornice and from this level onwards, the plane of the façade recedes diagonally, which means that from the top floor only the triangular bodies are visible from the street and, as they do not recede like the rest of the wall, they remain in the form of a tower.
The rounded corner has a tribune protruding from the mezzanine and acts as a balcony on the first floor. On the first, second and third floors there is a projecting cubic volume, the upper one less than the other two, and here there are windows. On the second and fourth floors there are balconies running around the corner, while on the third floor there are two balconies and the corner is left free. The fifth floor has no balcony, but is crowned by a cornice. The top floor is left as if it were a tower, as are the triangular bodies of the other two façades.
The facing is painted white except for the triangular bodies, balconies, the tribune and cornices, which are painted red. This play of volumes, emphasised by the use of colour, shows the influence of expressionism and cubism in the construction of the building.
