Designed by dIONISO LAB, this house is located in Póvoa de Varzim, Portugal, a city profoundly related to the sea and fishing. The house is simple… it is organized in a vertical and hierarchical way. The social areas are on the inferior floors and the private areas on the superior levels. To achieve great visual amplitudes and dynamic interconnections between spaces, the interior was structured in half floors. The width of the plot decided the stair. In fact, it became the heart of the house. A wall painted with Blue Klein emphasizes its importance and continuity through the spaces. The intimacy is guaranteed by stainless steel panels, perforated with the “siglas poveiras”. These symbols are a proto-writing system once used as a way of communication and to mark personal and fishing belongings. Also, they were hereditary and constituted an important family legacy that was transmitted by inheritance through generations, evolving with new combinations.
