The skinnySCAR project shows how forgotten empty spaces in the city can be used. Each city has neglected spaces that can be upgraded to complete the urban fabric while creating possibilities for new forms of urban living for the adventurous ones. As young architects, Gwendolyn Huisman and Marijn Boterman saw the potential and challenge of a narrow gap with extreme proportions in an old Rotterdam neighborhood. In 2012 they started the process to buy the plot that was not for sale, and recently finished the entire interior themselves.The extreme proportions of the plot, only 3.4 meters wide and 20 meters deep, resulting in a stacked open typology while it was a constructional challenge. Being this narrow and long in relation to the height, a massive foundation and load bearing structure were needed. Hence an elegant solution of two parallel reinforced concrete slabs was introduced in the interior of the house. This way the openings in the facades were not limited by the constructive constraints. In order to create tranquil living spaces, the architects have clustered all supporting functions that a dwelling needs, as well as these concrete slabs and installations, in two vertical volumes in the center of the house. These volumes are detached from the side walls to emphasize the 13-meter deep interior and create unexpected vistas in all directions between the different spaces. The staircase is designed in such way that it enhances these special qualities. The archite...
