Stefano Boeri Architetti, the Italian architecture firm has unveiled designs for the Blloku Cube, a mixed-use high-rise marked by its distinctive energy-efficient cladding. Located in the heart of Albania’s capital of Tirana, the Blloku Cube is a multifunctional center instrumental in the Tirana 2030 master plan — also designed by Stefano Boeri Architetti — that aims to breathe new life into one of the most prestigious districts in the city. The eye-catching cuboid structure was designed to enhance the vibrant district, which was reborn from a former military zone with restricted access into a major city hub flush with shops, bars and restaurants. Blloku Cube will comprise office space stacked atop multiple levels of retail. A Roof Garden Restaurant will occupy the seventh floor. “The identity of the building is strongly characterized by a special cladding, a standout feature that makes it recognizable and unique in the city skyline and, at the same time, highly performing in terms of thermal efficiency, thanks to a ‘double skin’ technological system,” the firm said in a project statement. Energy-efficient glass curtain walls are considered the first “skin,” and the second “skin” consists of a shimmering “sophisticated technological shielding system” made up of anodized aluminum modules carefully angled to filter the sunlight and optimize natural light indoors.
