The Barcelona firm Arquitectura-G – headed by Jonathan Arnabat, Jordi Ayala-Bril, Aitor Fuentes, and Igor Urdampilleta – designed this 1,000-square-meter block containing four flats and two duplexes. Carrer Praga bends toward the interior of the plot, forming a courtyard with plants onto which balconies at different altitudes open. The gesture results in a building that has no rear, but instead an urban exterior that brightens up and airs all the units. The circulation core is a small tower that generates interferences enriching the residential typologies, prioritizing use flexibility by means of movable dividers.
