The Downtown One skyscraper, designed by Dutch firm MVRDV, is set to become Albania’s tallest building, rising 140 m above Tirana’s skyline. Situated on Bajram Curri Boulevard, the 37 storey structure will incorporate a complex structural framework to support its distinctive pixelated facade, which represents a map of Albania. The building’s design includes numerous cantilevered volumes that extend from the main structure, requiring advanced engineering solutions to maintain stability and load distribution.
The primary structural system consists of a reinforced concrete core, providing lateral stability against wind and seismic forces. Steel-reinforced concrete columns and floor slabs support the load-bearing framework, ensuring the necessary strength to accommodate mixed-use functions. The cantilevered elements — projecting blocks forming the pixelated map; introduce additional structural challenges, necessitating the use of post-tensioned slabs and high-strength steel reinforcements to counterbalance their weight and maintain equilibrium.
The facade integrates a modular grid system, with deep structural framing to support the protruding volumes. Some of these units contain outdoor terraces, requiring additional load-bearing considerations to support vegetation and external use. The integration of these features contributes to the concept of a ‘vertical village,’ while also demanding precise calculations to prevent excessive deflections and vibrations in the overhanging sections.
A multi-level basement provides car parking facilities, requiring deep excavation and extensive foundation work to ensure structural integrity. Given the seismic activity in the region, the foundation system employs reinforced concrete piles and shear walls, designed to distribute loads efficiently and provide resilience against ground movement. The integration of modern construction techniques, including prefabrication of facade elements, enhances efficiency and reduces material waste. Downtown One is a key component of Tirana’s ongoing urban transformation, incorporating both architectural innovation and structural complexity.
