The building “La Galera” was built in 1865 and occupies a whole block of the Gumà building expansion in Vilanova i la Geltrú, the first major urban growth around the old town of the two original centres of the city. Close to Plaça de la Vila and Rambla Principal, this unique building was promoted by Joan Samà. A rich Indian man in La Habana who was able to accumulate an important property asset in Vilanova, like this housing block that is known to be the Civil Guard station for decades, but also for hosting other social headquarters and relevant cultural entities. La Galera thus describes, an absolutely atypical structural infrastructure for a multi-family residential built in the middle of 19 th century, where apart from a bearing perimeter façade, two longitudinal walls of three heights are constructed forming a large system of arches. Our proposal has been based on making these walls composed of arches visible, turning them into the focus of the house and adding them value as structural rhythm.
