Like the neighbouring Casa Bruquetas, this building stands on a plot seven metres wide and was rebuilt by Ucha with the addition of two storeys and an attic. As in other houses in the area, the architect created a modernist exterior for a façade with a traditional layout.

Casa Vázquez and Casa Bruquetas are considered to be part of what is known as popular modernism, a variant based on the cladding of the façade of traditional buildings with modernist woodwork. In this particular case, the architect went a step further and used the same decorative leitmotiv of circular shapes on the three levels of the galleries, both in the window frames and in the glass parapets on the first floor. Corbels are also used as unifying elements, which finish off each level and go into the next. The two galleries flanking the balcony on the first floor are finished with an openwork moulding of vegetal interlacing, while on the second and third floors variants of decorative dentils are used.
